Battery Statement
RF Code warrants all tags to be free from defects in materials and workmanship for a period of one (1) year.
Based on the ratings and specifications from the battery manufacturers, RF Code develops usage models to calculate the
life of the active RFID Tags. Like all models, there are assumptions and approximations involved. The values are to be
taken as engineering estimates and not as guarantees of performance.
In most asset tag deployment scenarios, RF Code tags with a 10-second beacon rate have a useful life of 5-to-7 years.
In most sensor tag deployment scenarios, RF Code tags will typically have a useful life of 3 or more years. Exposure to
extreme temperatures will shorten the battery life of any sensor tag.

Introduction and Overview
RF Code Active RFID tags are battery-powered RF transmitters that attach to items that need to be tracked, located and
identified. Every tag broadcasts its unique ID and a status message at a periodic rate (that is programmed at the factory).
With a modular design and low price, tags provide an economical solution to a wide variety of problems. RF Code's
patented communication protocols allow for very high tag densities. Large populations of tags can be deployed in highly
scalable asset tracking environments.
The read range for every RF Code Tag can be up to 300 feet, with the exception of the M131 Thin Tag, which has a read
range of up to 150 feet. However, read ranges are dependent upon the deployment environment because of specific
building materials and construction features, various obstructions, and other factors within the environment that can
decrease read ranges. For more information, refer to the RF Code Support Knowledge Base Article:
http://support.rfcode.com/customer/portal/articles/922012
RF Code tags operate at 433.92 MHz; they are one-way, transmit-only communicators. Patented RF Code communication
protocols were designed to provide reasonable protection against harmful interference. Every RF Code tag is powered by
a single coin cell (“watch”) battery (CR2032). Tags operate with a very low duty cycle and therefore have long battery
lives (typically 5 years with a 10-second beacon rate).
While most RF Code tags broadcast their status every 10 seconds*, each message is extremely short; therefore, each tag
has an actual total transmission time of less than 10 seconds per day. However, tag broadcast frequency does vary
slightly by tag type, as some send messages less often or more often. For more specific information about the
characteristics of each tag model, refer to the tables of M-series and R-series tags.
RF Code currently offers two series of Active RFID tags that work in conjunction with the RF Code line of Active RFID
Readers and RF Code enterprise class software to meet many different tracking and monitoring needs. RF Code offers MSeries and R-Series Tags. These series offer several models that provide different alert features such as motion and
tamper options. The M-Series tags operate at 433 MHz and are designed for general use in equipment and personnel
tracking. The R-Series tags also operate at 433 MHz, but are specially-designed with sensors and/or specific form factors
for IT assets. The R-Series tags are used for environmental monitoring in conjunction with RF Code Environmental
Monitoring Solutions for Data Centers as well as for tracking rack-level equipment and for monitoring equipment racks
and personnel with the use of RF Code M250 Readers.
In addition to the two series of tags (M and R) available from RF Code, many tag models have an identical or similar
version provision with infrared capabilities for use with RF Code Room and Rack Locators to provide even more precise
determination of asset location. IR-enabled tags monitor their environment for incoming IR signals and periodically
report both their own unique ID and IR location codes received from Room or Rack Locators. Since the location of IR tags
is determined via the IR room code, there is no need for performing complicated signal strength calculations to
determine tag location.
Most tag models can be customized to support a broad range of integrated sensors in order to monitor tag status.
Motion activated tags can be programmed to operate at two different beacon rates: slow (every 10 seconds) when the
tag is stationary and faster (every 2 seconds) when the motion sensor is activated (to provide immediate notification
when objects are moving). 2 second beacon rates are for use in safety and security applications. Tamper switches can be
installed to trigger an alert if a tag is removed.
IR tags are designed to be deployed in concert with RF Code IR Room Locators. IR-enabled tags monitor their
environment for incoming IR signals and periodically report both their own unique ID and IR location codes. Motion
activation allows the tag operate at 2 beacon rates: slow when the tag is stationary and faster when the motion sensor is
activated. This provides a method for rapidly locating mobile assets with room-level accuracy.

Using RF Code Tags in Data Centers
Typical RFID applications include item tracking, inventory control, asset management and physical security. A specific
example is the tracking of servers and network equipment in the data center. The impact of RFID on IT systems depends
on three factors: the power of the transmission, the distance from the emission source, and the type of equipment in the
path of the transmission. Transmission power is strictly regulated by governments to ensure that IT devices can coexist
with RFID systems. Part 1 of the US FCC Part 15 mandates that a certified wireless device may not cause harmful
interference. Moreover, most IT equipment is enclosed in a metal casing that is RF-opaque to UHF transmissions at 433
MHz. RF Code tag transmissions do not penetrate the metal casings of typical IT equipment.
RF Code systems do not have any negative affect on IT equipment in a data center or in similar environments like
telecommunications centers. Over two million (2,000,000+) RF Code tags have been deployed in the past decade, with
more than 100,000 tags mounted directly on IT servers. There has never been a report of data loss or degradation in any
storage or security device due to the presence and/or operation of RF Code tags and readers.
General Cleaning Procedures for RF Code Tags
RF Code’s Active RFID Tags are water-resistant to sustain repeated wipe-down procedures and they are robust with
respect to daily cleaning with PDI sanitary wipes or similar products. Use a soft, slightly damp cloth, but avoid the use of
window cleaners, solvents or abrasives. The enclosure and internal battery are rated for operation up to 70 degrees
Celsius. Tags should not be subjected to elevated temperature cleaning cycles such as a dishwasher, pressure washer or
autoclave. Cleaning instructions for specific tag models are provided in sections of this document specific to those tag
models.

R-Series Tag – General Use and Deployment Instructions
R100 IT Asset Tag
The R100 IT Asset Tag is designed for use with U-mounted racked assets.
R104-i IT Asset Tag
The R104-i Tag is designed for use with rack-mounted assets and should be
deployed in concert with RF Code's A740 Rack Locators and A750 Room Locators.
Mounting R100 and R104-i Tags
To mount R100 and R104-I Asset Tags, follow these guidelines and instructions:
•
Place the tag directly on the surface of the asset; do not attach it to the bezel.
•
Mount all tags consistently on each type of asset.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
9
•
Trim the tongue of the tag if necessary to more properly fit mount the tag with your rack configuration.
However, do not trim the adhesive completely from the tag or it will no longer stick to the asset.
•
Remove the adhesive backing liner from the tongue and apply adhesive side down to the surface of the asset.
The tag adhesive bonds when force is applied, rather than by air activation. The tag should be forcibly pressed
down on the surface of the asset with 15 pounds of force for more than two seconds. The ideal adhesive application temperature range is 60°F (21°C) to 100°F (38°C). Application is not recommended if the surface
temperature is below 50°F (10°C) because the adhesive becomes too firm to adhere readily. R104 tags should be
installed with the IR lens side down (label side up).
Active RFID Tags: Features, Specifications, and Deployment Guidelines
10
•
Tags should be installed on an asset where the tag is located at least three inches away from the IR strip or side
of the rack for use with the A740 Rack Locator. This will allow the tag to receive a maximum coverage from
multiple IR LEDs. It will also help to prevent the asset tags themselves from blocking a significant amount of any
IR LED’s transmission coverage.
R110 Flex-Mount Tag
The R110 Flex-Mount Tag is designed for flexible mounting on assets such as blade
servers and tower equipment.
R114-i Flex-Mount Tag
R114-i IR Tag is designed for use with rack-mounted assets and is deployed in concert
with RF Code's A740 Rack Locators and A750 Room Locators.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
11
Mounting R110 and R114-i Flex-Mount Tags
To mount R110 and R114-I Flex Mount Tags, use one of the following two methods:
A. Remove the adhesive backing liner and apply the adhesive side down to the surface of the asset.
B.
Alternatively, for a flexible mounting option, slide a zip-tie through the slot on the top of the tag and then
through an opening on the asset to be tracked. Then, close the zip tie and trim the tail of it, if necessary.
NOTE: R114-i tags should be installed with the lens side facing equipment (label side out), with the tie wrap inserted
through the tag hole that is positioned furthest from the IR lens. (i.e.; tags lens positioned towards bottom).
NOTE: R114-i tags should be installed with the tag placed at the same distance or plane in reference to the IR strips
installed for use with the A740 Rack Locator. Optimal rack configurations will have tag mounted where there
is a slight bend downward when attached to the asset.
NOTE: R114-i tags should be installed on an asset where the tag is located, at least three inches away from the IR
strip or side of the rack. This will allow the tag to receive a maximum coverage from multiple IR LEDs. It will
also help to prevent the asset tags themselves from blocking a significant amount of any IR LED’s
transmission coverage.

R120 Door Tag
The R120 Door Tag is designed for security applications monitoring room and rack doors. The tag is installed on the door
or door frame. Once installed on the door frame the R120 will monitor and report the door status, enabling you to track
attempts to access equipment within the racks.
Mounting R120 Door Tags
To mount R120 Door Tags, follow these instructions and guidelines:
1.
Position the magnet on the frame of the door in proximity of where the R120 Door Tag will be positioned.
2.
Remove the adhesive backing liner from the magnet or use the supplied screws to attach the magnet to the
corner of the door frame.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
13
3.
Remove the adhesive backing liner of the Door Tag and apply it to the corresponding corner of the door or
equipment rack door. The tag adhesive bonds when force is applied, rather than by air activation.
NOTE: The tag should be forcibly pressed down on the surface of the asset with 15 pounds of force for more
than two seconds. The ideal adhesive application temperature range is 60°F (21°C) to 100°F (38°C).
Application is not recommended if the surface temperature is below 50°F (10°C) because the adhesive
becomes too firm to adhere readily.
The R120 Door Tag must be mounted in such a way that the right or bottom edge of the tag is in close proximity to the
magnet. Otherwise the tag may not be able to sense the magnet and could indicate the door is open when the door is
actually closed.
Right-Side Positioned Magnet: In this tag mounting configuration the magnet is positioned to the right of the R120 Door
Tag within 1/2” of the tag in order to ensure proper readability and to avoid tag reporting errors.
Install the R120 Door Tag on the inside of the entrance door, near the top of the door. Make sure the magnet is within
1/4” of the door tag, and near the indication arrows that are printed on the door tag label (Figure 3).

R130 Dry Contact Tag and R131 IR-Enabled Dry Contact Tag
The R130 and R131 Dry Contact Tags are designed to be paired with a wide variety
of dry contact sensors to allow real time monitoring of the sensors' state. Typical
applications of the R130/R131 include but are not limited to use with fluid
detectors, IR motion detectors, alarm relay contacts, moisture sensors, and door
switches. When connected to a device with dry contact outputs, the tag will report
the current open or closed state of the dry contact device. The R131 has an onboard IR sensor and is designed for tracking large, valuable assets that may
periodically move between locations (such as laboratory freezers, bio freezers, and refrigerators). Dry contact devices
have terminals that are either “closed” or “open” to indicate that a condition is normal. When something happens, such
as an interruption of power, the dry contact terminals indicate an abnormal state for the device. Until now, the standard
for monitoring this state change has been done with wired dry contact systems, with cables and wires linking the dry
contact monitoring system to a power source. Such wiring is not only expensive, it’s rigid and if the equipment is moved,
the cabling has to be redone.
Once connected to a dry contact device, the battery-powered R130/R131 will monitor and report the open and closed
state via RF transmissions. While in steady state, the tag will report the dry contact status once every 10 seconds. When
the dry contact state changes, the tag will immediately broadcast three beacons at 0.5 seconds apart with the new dry
contact status then return to beaconing the new condition once every 10 seconds.
R130/R131 Tags have a minimum switching time of 200ms for both open and closed state transitions. Meaning, the tags
are only intended to be used with devices that will be in the open or closed states for more than 2/10ths of a second. If
the dry contact device switches from one state and back faster than 200ms the tag will not report the state change.
IR-enabled tags are designed to be deployed in concert with RF Code’s IR Room Locators. These tags monitor their
environment for incoming IR signals and periodically report both their own unique ID and IR location codes. This provides
a method for rapidly locating mobile assets with room-level accuracy. Since location is determined via the IR room code,
there is no need for deploying multiple overlapping readers or performing signal strength calculations or triangulation.
The R130/R131 tag should be mounted on top of, or within a few feet of, the dry contact equipment. The R131 tag ships
with an integrated 8-foot 24 AWG stranded cable that can be cut to length. Tags can be mounted using either the
industrial-strength adhesive backing or by using the supplied plastic screw mount. The tag enclosures are impact resistant
and temperature stable. R130/R131 tag battery life is typically 5 years.

R135 Fluid Detector Tag
The R135 Fluid Sensor Films attaches to an RF Code active RFID sensor tag via a three meter cord. This provides maximum
flexibility in sensor tag placement. Information captured by the sensor tag is instantly broadcast, providing real-time
monitoring and alerting about environmental conditions at a site. The R135 tag is designed to be deployed in a variety of
challenging environments to monitor areas such as floor or ceiling mounted pipes, areas under or above a raised floor,
for monitoring water delivery systems and chillers, and for use with air conditioning units and walls.
R135 Fluid Tag Details
The R135 Fluid Sensor Tag is a real-time liquid detection sensor that eliminates the need to wire or cable a data center for
liquid leak detection capabilities. Combining thin-film technology with RF Code’s wire-free environmental monitoring
technology, the sensor provides the ability to deploy liquid detection wherever vulnerabilities to conductive liquids
threaten valuable assets. The unique qualities of this thin-film sensor make is easy to deploy this sensor in a variety of
previously difficult to monitor areas such as:
•
Floor-mounted or ceiling-mounted pipes
•
Vulnerable floor areas including areas under or above a raised floor
•
Water delivery systems and chillers, including those found under raised floors in older data centers
•
Air conditioning units and walls
Mounting the R135 Fluid Tag
RF Code recommends using one of the mounting methods described below:
R135 Fluid Tag Pipe Wrap Mounting
In this mounting method, you will attach the R135 Fluid Detector Tag around the surface of a pipe or other rounded
structure to monitor for fluid leaks. When doing so, follow these guidelines and instructions:
•
Apply the adhesive pad that was supplied to the back side of the sensor connector.
•
Remove the release liner from the back of the adhesive pad and position and press firmly to apply the sensor
connector on the pipe.

Remove the release liner from the back of the adhesive on the sensor film and wrap the fluid sensor film around
the surface of the pipe with the top side (side with the holes) pointing away from the surface of the pipe.
Ensure that you do not overlap the sensor film.
•
Secure the sensor film to the pipe by zip-tying around the sensor film and pipe at periodic intervals across the
length of the sensor film.
•
Although the sensor film is flexible and allows for bending, take care to avoid creasing or pinching the sensor film
as this can cause the film to not work properly.
R135 Fluid Tag Wall Mounting
When mounting the R135 Fluid Tag to a wall, follow these guidelines and instructions:
•
Position the R135 Tag on a wall near the pipe above the sensor connector.
•
Apply the adhesive pad that was supplied to the back of the tag.
•
Remove the release liner from the back of the tag and press firmly to mount the tag to the surface of the wall or
use screws to screw the tag and mounting bezel to the wall.
Tie-Wrap Mounting
If mounting the tag in an area where it could potentially be bumped or snagged, you may want to use a strain relief
method with the supplied tie-wrap and tie-wrap mount in order to position the sensor connector wire in such as way that
if snagged, the wire will not be ripped from the tag.
Flat Surface Mounting
In this mounting method, you will attach the R135 Fluid Detector Tag to a flat surface such as a floor or wall. When doing
so, follow these instructions and guidelines:
•
Remove the release liner from the bottom side of the sensor film and position the sensor film on the section or
floor. Press firmly along the surface of the sensor film ensuring that there are no bubbles or kinks in the sensor
film and that it is smoothly flattened against the floor or wall surface.
•
Apply the adhesive pad that was supplied to the back side of the sensor connector. Remove the release liner
from the adhesive and position the sensor connector on the floor or wall. Press firmly to adhere the connector.

•
Run the connector wire up or along the wall or surface. Apply the adhesive pad that was supplied to the back
side of the tag. Remove the release liner and press firmly to mount the tag to the wall or use screws to mount
the tag using the screw mount bezel.
•
If mounting the tag in an area where it could potentially be bumped or snagged, you may want to use a strain
relief method to position the sensor connector wire in such as way that if snagged, the wire will not be ripped
from the tag.
•
Please note that the tag must be mounted in such a way where it will have an unobstructed proximity to the
reader to ensure a correct detection beacon. For example, if mounting the sensor film under a raised floor, the
tag will most likely need to be mounted above the raised floor in order for beacons to be detected.
•
The R135 Fluid Sensor is designed for detecting fluid in areas where fluid is not a normal occurrence. The sensor
should not be used in any application where the sensor is normally in a wet state and is required to a report dry
state as an alert condition. After the Fluid sensor has become wet it should be dried and retested for proper
operation.

NOTE: Although the badge tag has been tested and shown to work properly while carried in a wallet or pocket, the best
read-range is achieved through using the lanyard mount, keychain clip or clothing clip method.
The R142-I Badge Tag is ideal for deployment in hospitals when used with A760 Proximity Locators. The deployment
configuration enables hospital administrators to know when health staff enter and exit rooms in order ensure that
patients are seen in the most efficient and effective manner. When used with hand sanitation dispensers, the R142-I
badge tag helps to ensure that hospital staff properly attend to personal hygiene in order to minimize the transfer of
potentially harmful micro-organisms between rooms and patients.

R150 Temperature Tag
The R150 Temperature Tag monitors and reports the ambient temperature in its immediate environment. The R150 is
designed to report temperature within + /- 1°C, (1.8°F), in environments ranging from -20°C to +70°C. It can be used to
monitor the temperature within individual racks or to monitor the temperature in different areas of a data center.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
21
R155 Humidity-Temperature Tag
The R155 Humidity-Temperature Tag monitors and reports the relative humidity and ambient temperature in its
immediate environment. It is designed for use in environmentally-sensitive areas, such as IT data centers. This affordable
sensor tag is mounted in an impact resistant polycarbonate enclosure with strong adhesive on the back of the case. The
tag has reliable performance with an operating range from -20°C to +70°C and 0% to 95% RH. In temperature-controlled
settings, such as offices and data centers, the sensor has an accuracy of +/- 0.3°C and +/- 2% RH (typical).
Mounting R150 and R155 Sensor Tags on Assets or Walls
When mounting R150 and R155 Sensor Tags, follow these guidelines and instructions:
•
If mounting on an asset or wall, ensure that the surface of the intended asset or wall is clean and dry. The tag
should be forcibly pressed down on the surface of the asset with 15 pounds of force for more than two seconds.
The ideal adhesive application temperature range is 60°F (21°C) to 100°F (38°C). Application is not
recommended if the surface temperature is below 50°F (10°C) because the adhesive becomes too firm to adhere
readily.
•
If mounting on a wall, take care to avoid mounting near windows as this will impact the tag’s ability to accurately
monitor temperature. Avoid mounting the tag directly to a metal wall surface or in direct sunlight because this
can affect read-range and temperature.
•
RF Code advises mounting the tag in a vertical orientation where the cut-out for the humidity sensor is vertical
or mounted in such a way that the sensor is pointing down to prevent dust and debris from gathering in the cutout and creating humidity reporting errors.
•
Avoid mounting tags close to the ground as this may negatively impact read-range.
Mounting R150 and R155 Sensor Tags on Racks
To mount this tag in or on a rack, use one of the recommended mounting positions discussed below.
NOTE: The R150 Rack Temperature Tag and the R155 Rack Humidity-Temperature Tag must be mounted in a position
that will allow the sensor on the tag to monitor the temperature of the surrounding area of the assets that you
would like to monitor.
•
To mount this tag on the door of a rack, remove the release liner of the adhesive backing of the temperature tag
and press the tag firmly into place centered on the outside of the rack door.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
23
•
To mount this tag in a using a zip-tie, you will need to have a lanyard bezel (optional). Slide the zip-tie through
the lanyard bezel and find and appropriate place on the outside of the rack to secure the end of the zip-tie.
NOTE: For more information on deploying R150 and R155 in a data center for environmental monitoring, refer to the
following RF Code Support Knowledge Base article and document here:
http://support.rfcode.com/customer/portal/articles/976954
Installing Sensor Tags in Network Closets
For best read range, mount sensor tags at least five (5) feet from the floor and so they are not shrouded by metal, i.e., do
not install sensor tags inside equipment racks, such as half-way from front to back or on enterprise computing equipment
within the racks.
An example minimal server room deployment is shown below:
A. R155 Temperature-Humidity tags (A) are on the outside of equipment racks to monitor equipment intake and
exhaust air.
B.
The R150 Temperature Tag (B) is placed to measure AC supply temperature.
C.
The R120 Door Tag (C) is mounted on the inside of the room entrance door to monitor unauthorized room
access.
D. The reader (D) is mounted on the cable tray between the racks being monitored.

Install one R155 Temperature-Humidity Tag on the front side and one on the rear side of the equipment rack, or one
sensor each on the front of rack containing critical equipment. If the racks have mesh doors, install the tag on the outside
of the rack door. If the racks do not have doors (e.g., open racks or two-post racks), affix the tag anywhere near the IT
equipment about five (5) feet above the floor. Affix the tags using the adhesive pads or the zip-ties and the lanyard
mounts included in the bundle.
NOTE: Do not affix the sensor tags to the IT equipment directly.
Install one R150 Temperature Tag near the AC supply for the room, preferably in the air stream, or mount it in another
area of the room where you want to monitor ambient air temperature.
Sensor Tag Deployment in Data Centers to Monitor RCI
When placing sensor tags in a data center in order to monitor RCI, follow these guidelines:
Attach your tags to the outside of rack doors using either the attached adhesive or optionally the lanyard bezel and a zip
tie that is included with the tags. The former method (using adhesive) allows easier replacement of the sensor battery
when necessary and requires a smaller footprint. The latter method (using the lanyard bezel) is often just a personal
preference of data center managers. With both methods, attaching the sensor tags to the outside of the rack doors
provides the best read range.
For RCI metrics, RF Code’s minimum recommendation is that you place at least three temperature tags on the front (top,
rd
middle, and bottom) of every third (3 ) rack door. However, for the most accurate and granular data, you should place
three temperature tags on the front (top, middle, and bottom) of each and every rack. If the racks have no doors, attach
the sensors to the inside wall of the rack.
Figure: Three sensors (depicted as blue rectangles within red frames) mounted on the outside of every rack door.
Active RFID Tags: Features, Specifications, and Deployment Guidelines

Active RFID Tags: Features, Specifications, and Deployment Guidelines
26
Figure: An R155 temperature-humidity sensor mounted on the inside of a rack (left side of photo) near an R104-I IT Asset
Tag (right side of photo)
An RF Code best practice is to place temperature sensors at the top and bottom and a temperature-humidity sensor in
the middle of the rack door. While not specifically necessary for RCI metrics, using temperature-humidity tags gains you
visibility to humidity levels as well as to heat in the server racks and rows, which further enhances your ability to monitor
and manage your data center environment.
NOTE: Do not mount tags on hot surfaces, such as directly on a reader or on a server chassis; doing so can cause them to
report inaccurate data.
R151 Tethered Temperature Sensor Tag
As an alternative to using the R150 Temperature Sensor Tag, the R151 form factor can be deployed in environments
where the RF transmitter (tag) module is mounted in open space while the temperature sensor is installed inside RFblocking enclosures such as a metal ductwork or refrigerators. Mounting is easy and flexible; the tethered sensor can be
routed into difficult to reach places, such as above a suspended ceiling or inside HVAC air ducts.

Temperature Sensor Calibration
RF Code R150, R151 and R155 sensor tags have temperature-sensing components that are calibrated at the factory
during the manufacturing process. These are silicon-based chips that don’t require field calibration or re-calibration over
time. As the ambient temperature moves toward the extremes, sensor accuracy decreases slightly. The chart below
illustrates this concept.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
28
The precision of the reported temperature data is also important. Temperature sensor data is handled by multiple RF
Code components as part of the overall solution that includes RF Code Readers and RF Code software (Zone Manager and
Asset Manager). The following table shows the data precision for each product.

Temperature Sensor Performance in Typical Data Centers
Data center temperatures typically range from about 60° to 110° F (15° to 45° C) with a relative humidity range of 30% to
60% RH. In this environmental range, the sensors for the R150, R151 and R155 deliver their best, most accurate
performance. This is true because the calibration coefficients are selected to ensure the most accurate readings in this
specific range. The most accurate sensor is the R155 Humidity & Temperature Sensor that provides better than one
quarter of one degree Celsius accuracy in the typical data center temperature range, including allowance for quantization
error.

R160 Differential Air Pressure Sensor Tag
The R160 Differential Air Pressure Sensor monitors and
reports the differential air pressure reading between two
points. It is typically installed under raised floors in data
centers or in critical areas in hospitals where
positive/negative air pressure is needed.
R160 Air Pressure Tag Details
The R160 Differential Air Pressure Sensor is used to
measure air pressure difference above vs. below a raised
floor, in a room vs. hallway (patient room monitoring), or between other areas in a data center. It reports its unique ID
along with the sensor data observed by the tag to an RF Code fixed reader and then to the RF Code software stack (first
to Zone Manager and then to Asset Manager). It includes 8 feet of flexible tubing to achieve physical separation between
the +/- sensor terminals.
The R160 sensor can be mounted with strong adhesive on the back of the case, or via hardware/screws or zip-ties
through the mounting holes.
Mounting R160 Tags

Overview of RF Code PDU and CDU Sensor Tags
RF Code offers PDU and CDU sensor tags for specific families of PDUs and CDUs offered by our partners. The following
sections offer some specific Instructions and guidelines for these similar configurations. All power data collected from the
rd
PDU by the sensor tag flows to the RF Code readers, then to Zone Manager, and finally to Asset Manager and other 3 party applications. Tags connect to the PDU/CDU via an integrated 7-foot cable with an RJ-12 or RJ-45 connector, as
appropriate.
Powered by a replaceable coin cell battery, the R170 tag will perform reliably in any data center environment (the tag’s
specified operating temperature range is -20 to +70 degrees Celsius). R170 tag cases are impact resistant and
temperature stable. The R170 tag operates with a very low duty cycle that translates to long battery life (typically > 5
years). Featuring a low-battery alert, the tag will continue to report PDU operational data for at least three months
following this alerting.
Each tag broadcasts its unique ID and a portion of the PDU data once every 10 seconds using RF Code’s patented
communication protocol. The Asset Manager software presents all of the collected power parameters and computes
additional attributes from this data to provide a complete picture of power utilization. Power attributes can be visualized
via live table and map views, interactive graphing, and scheduled reports and graphs.
R170 PDU Sensor Tags only receive information from the PDUs. The tags do not allow any commands to be received by
the unit, hence no outlet switching or other actions are possible through the tag. This means the RF Code wireless
solution does not compromise power security.
Active RFID Tags: Features, Specifications, and Deployment Guidelines

R170 PDU Sensor Tag Operational Notes
The following notes about the general operating characteristics of PDUs and PDU tags should be taken into consideration:

Allow at least two hours for power information to become available in the RF Code software due to the time
delay inherent in collection and transmission of data, which helps to ensure its accuracy and usability.

Missed beacons will cause further time delays in the reporting cycle so they should be eliminated as much as
possible by proper positioning of the tags.

High levels of noise and/or tag densities in the deployment environment may require the installation of
additional readers in order to assure successful delivery of data from the R170 to Zone Manager and
subsequently to Asset Manager.

R180 4-20mA Sensor Tag
The R180 4-20mA Sensor Tag is designed for deployment with industrial process control equipment, devices, and sensors
that use 4-20mA current loops. This enables wireless transmission of industry-standard 4-20mA sensor readings for
specialty and industrial applications.
R180 4-20mA Sensor Tag Details
The 4-20 mA current loop is a common method of relaying sensor information in monitoring applications with a need for
analog sensors. The 4-20 mA sensor is a device used to measure physical parameters (such as temperature, pressure,
speed, liquid flow rates), with 4 mA representing the lowest end of the sensor range and 20 mA representing the highest
sensor reading. The R180 Sensor Tag allows the 4-20 mA monitoring data to flow over the RF Code radio frequency
infrastructure. Data transmitted from the sensor tags is captured by the RF Code reader infrastructure and relayed to the
rd
RF Code software (Zone Manager/Asset Manager) or into other 3 -party applications. The 4-20 mA current loop readings
can be visualized in Asset Manager via:

Live table and map views

Interactive graphing

Scheduled reports and graphs

Alerting and thresholding
Active RFID Tags: Features, Specifications, and Deployment Guidelines
38
These tags report their own unique ID and a portion of the 4-20 mA loop current value once every 10 seconds using RF
Code’s patented communication protocol; this results in three (3) sensor readings per minute.
4-20 mA supported specifications:

1.25 uA resolution

±0.5% accuracy

100 ohm resistance

Loop supply not included; the sensor must provide the power (or a separate power supply is required)
The R180 ships with an 8-foot 24 AWG stranded cable that can be cut to fit or spliced.
Powered by three (3) field-replaceable coin cell batteries, the R180 tag will perform reliably in an operating temperature
range from -20 to +70 degrees Celsius. R180 tag enclosures are impact resistant and temperature stable. The R180 tag
operates with a low duty cycle that translates to long battery life (typically > 5 years). Featuring a low-battery alert, the
tag will continue to report 4-20 mA data for at least three months following this alert.

Mounting Instructions for Standard Form Factor Asset Tags
The following mounting instructions apply to M100, M102-I, M131, M171, and M172-i asset tags:
1.
Ensure that the surface of the asset is clean and dry.
2.
Remove the liner backing of the adhesive and apply firmly to the surface of the asset. The tag adhesive bonds
when force is applied, rather than by air activation.
3.
Press the tag down on the surface of the asset with 15 pounds of force for three (3) seconds or longer.
NOTE: The ideal temperature range when applying these tags with adhesive is 60°F (21°C) to 100°F (38°C). Do
not try to mount these tags with adhesive if the surface temperature is below 50°F (10°C) because the
adhesive becomes too firm to adhere readily to the asset surface.

Attaching M163 and M163-i Wristband Tags
To attach an M163 or M163-i wristband tag, perform the following steps:
1.
Slide a standard single-use ¾” wristband through the slots at the base of the tag.
2.
Ensure that the wristband is on the backside of the tag (opposite side of the tag label) and slide the end of the
wristband through the slot at the top of the tag.
3.
Wrap the wristband around the wrist of the person who will be wearing it and then close the clasp to secure the
tag.
NOTE: Please take care when attaching the wristband; ensure that it is comfortable to wear and still securely
attached so that it will not slip-off.
4.
If necessary, trim the wristband.
M163 and M163-i Wristband Tag Construction and Cleaning Information
M163/i Wristband Tags can be regularly and repeatedly exposed to warm soapy solutions. Tags will withstand normal
bath and shower regimens, wipe-down and cleaning procedures. The wristband is disposable, but the tags are designed
to be cleaned periodically or when necessary. When unused, tags should be stored in dry conditions.
The enclosures for the M163 family of active RFID wristband tags are injection-molded from polyvinyl chloride
(PVC) Novablend 2677 (manufactured for RF Code by PolyOne Corporation). CLINI-TECH® disinfectant (by Medtrol) is a
recommended cleaning agent (containing n-Alkyl dimethylbenzyl ammonium chloride and n-Alkyl dimethylethylbenzyl
ammonium chloride both at a concentration of 0.105% per volume as the active ingredients).
To clean M163/i Wristband Tags, follow the instructions in the next section.

Precautionary Notes

Diluted chlorine bleach (up to 1:10 bleach solution ratio, or 5000 ppm available chlorine) may be used for tags
that have been exposed to certain infectious diseases. Use of higher bleach concentrations is not recommended;
please refer to hospital infection control policies.

The tag enclosure and internal battery are rated up to +70 degrees Celsius (158 °F). Do not subject tags to
elevated temperature cleaning cycles such as a dishwasher or autoclave.

The enclosure is sealed via ultrasonic welding. If the tag is subjected to sustained loads under harsh or hostile
environmental conditions, the enclosure may show signs of environmental stress cracking.

The propagation of cracks over time can result in cosmetic and functional defects (e.g., broken seal, water
penetration, electronic failure).

Do not clean with window cleaners, solvents or abrasives. Exposure to certain chemicals, including ammonia,
highly concentrated alcohol solutions (e.g., 100% isopropyl alcohol) and oil-based products (e.g., mineral oil,
vegetable oil) can accelerate the stress cracking process.

Customers are encouraged to evaluate product performance and fitness for use in their operating environment
before deploying large populations of tags.

M172 Durable Tag
The M171 Durable Tag is designed with a sealed, water-resistant, crush-proof, temperature-stable enclosure for generalpurpose asset tracking. The durable enclosure provides protection in harsh environments where liquids and/or extreme
temperatures are potential hazards.
M172-i Durable Tag
The M172-i Infrared Durable Tag is identical to the M172 with the addition of on-board infrared (IR) and motion sensors.
When used with the A750 Room Locator, these tags provide room-level location accuracy.
M172 and M172-i Durable Tag Details
Durable M172 tag labels are sealed on the inside of the clear polycarbonate enclosure via sonic-welding. This protects
both the label and the electronics from moisture and fluids. M172/i Tags can withstand salt water splashes, cleaning
solutions, germicides, disinfectants, etc. Powered by a coin cell battery, the tags will perform reliably in extreme
temperature environments (from -20 to +70 degrees Celsius) and after exposure to high humidity and/or to extreme hot
and cold cycles.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
46
M172 and M172-i Durable Tag Deployment
The M172 and M172-i Durable Tags are particularly well-suited for hospital asset tracking. The tags can be deployed on
expensive medical equipment so that these valuable assets can be located quickly for use in life-saving and other
situations.

M172-I Durable Tags deployed on a wheelchair and underneath a patient bed.
Cleaning M172 Durable Asset Tags
The M172 Durable Asset Tag enclosure is injection molded from polycarbonate (PC) thermoplastic polymers.
Polycarbonate is a very durable material, with high impact-resistance and can undergo large plastic deformations without
cracking or breaking. This polymer is highly transparent to visible light and has better light transmission characteristics
better than many kinds of glass.
Tag Enclosure Sealing
The tag enclosure is sealed using an ultrasonic welding process. If the tag is subjected to sustained loads under harsh or
hostile environmental conditions, the enclosure may show signs of environmental stress cracking. The propagation of
cracks over time can result in cosmetic and functional defects (e.g., broken seal, water penetration, electronic failure).
Any product containing plastic material is susceptible to time-dependent viscoelastic cracking. Exposure to certain
chemicals [including ammonia, highly concentrated alcohol solutions (e.g., 100% isopropyl alcohol) and oil-based
products (e.g., mineral oil, vegetable oil)] can accelerate the stress cracking process. Customers are encouraged to
evaluate product performance and fitness for use in their operating environment before deploying large populations of
tags. RF Code, Inc. warrants all tags to be free from defects in materials and workmanship for a period of one (1) year.

M174-i IT Asset Tag (shown with red tab installation tool)
The M174-i Infrared IT Asset Tag is designed for use with rack-mounted assets and should be deployed in concert with RF
Code's A740 Rack Locators and A750 Room Locators to provide room-level and rack-level location accuracy. M174-I tags,
which are 40% smaller than R104/R114 tags, are deployed using one of a variety of “tabs” that is appropriate for the
application. Different tab form factors facilitate the tagging of otherwise difficult-to-tag items. Another benefit of the tab is
that the asset tag is easily reused by simply replacing the tab with a new one.
OTAB-i010 - Flag tab (R100-type)
The Flag tab shown above is typically used on rack-mounted IT assets and can be considered a reusable version of the
R104 IT Asset tag.
OTAB-i020 - Thin Loop Tab (Feed-Thru)
The Thin Loop Tab shown above is typically used on small, difficult-to-tag IT assets such as blade servers and can easily be attached to
handles of IT assets.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
48
OTAB-i030 - Thumbscrew tab
The Thumbscrew tab, as the name implies, is designed to be mounted on the thumbscrew of difficult-to-tag items such as switch gear.
M174-i IT Asset Tag Details
M174-i enclosures are made of black IR-friendly plastic. The tag contains four IR sensors to receive IR from any direction.
The low profile tag accommodates several tab form factors (sold separately) so that the tag can be installed on a wide
variety of assets. A 10-second/50-second beacon rate maximizes scalability of the asset tracking solution in crowded
environments such as data centers.
M174-i IT Asset Tag Deployment
All tabs can be installed into the M174-i tag by using the included installation tool. The thumb-sized installation tool can
be used as a lever to open and close the M174-i enclosure so that the tabs can be inserted or removed. Tabs are keyed so
that they can only be inserted one way. Once installed, the tabs can withstand a pull force of about 10 lbs. before
breaking. In most situations, it is easier to mount the tab on the asset and then attach the M174-i to the tab.
Alternatively, the M174-i can be mounted on the tab and then the tab can be mounted to the asset. In summary, the
deployment method may be a matter of personal preference.
M174-i Installation tool
To mount M174-I IT Asset Tags using the Flag tab (OTAB-i010), follow these guidelines:
•
Place the tag directly on the surface of the asset; do not attach it to the bezel.
•
Mount all tags consistently on each type of asset.
•
Trim the tongue of the tag if necessary to more properly fit mount the tag with your rack configuration.
However, do not trim the adhesive completely from the tag or it will no longer stick to the asset.
•
Remove the adhesive backing liner from the tongue and apply adhesive side down to the surface of the asset.
The tag adhesive bonds when force is applied, rather than by air activation. The tag should be forcibly pressed
down on the surface of the asset with 15 pounds of force for more than two seconds. The ideal adhesive ap-

plication temperature range is 60°F (21°C) to 100°F (38°C). Application is not recommended if the surface
temperature is below 50°F (10°C) because the adhesive becomes too firm to adhere readily.
•
If possible, tags should be installed on an asset where the tag is located at least three inches away from the IR
strip or side of the rack for use with the A740 Rack Locator. This will allow the tag to receive a maximum
coverage from multiple IR LEDs. It will also help to prevent the asset tags themselves from blocking a significant
amount of any IR LED’s transmission coverage.

M175 Rugged Tag
The M175 Rugged Tag is designed with a sealed, water-resistant enclosure for general-purpose asset tracking in harsh
outdoor or environmentally exposed locations. A 10-second/50-second beacon rate maximizes scalability of the asset
tracking solution in crowded environments.
Deploying M-Series Asset Tags for Distributed Asset Tracking
Laptop computers, desktop computers, printers, and copiers are all considered distributed assets. Depending on the type
of distributed asset that you want to track, follow the recommendations below specific that or those asset types.
Attaching Asset Tags to Laptop Computers
RF Code recommends that the M131 Thin Tag is used for tracking laptops and other portable digital devices. RF Code
recommends that you DO NOT use this tag for mounting on objects that have dense metal surfaces such as desktop
computers. The metal surface has been found to diminish signal transmission and read-range for this tag. This tag has
been tested to work properly when mounted anywhere on the surface of the lid of the laptop but it is recommended for
troubleshooting purposes that all tags are mounted consistently in the same place among all of the laptops that you
intend to track.
Attaching Asset Tags to Desktop Computers
Use the R100 Tag or the M100 Active Tag (or the M102-i Infrared Tag) for tracking desktop computers. The tag should be
placed on the upper portion of the tower, toward the back and opposite to the power supply cable in order to get the
best signal and read range.
Active RFID Tags: Features, Specifications, and Deployment Guidelines
53
Attaching Asset Tags to Printers or Copiers
Use the R100 Tag or the M100 Active Tag in order to track printers and copiers. Mount these tags on the upper portion of
the asset for the best read-range and signal transmission. Mount the tag on a flat surface in order to ensure good
adhesion.
