Overview
1.1. Introduction
The IAM-100 is a system that combines sensor and monitoring features
in an integrated unit. It is a stand-alone system used to detect gases in
an area, room, zone, airspace or airflow.
The IAM-100 can be expanded into large gas detection systems using
the optional IAM controller.
Up to 16 IAM-100s can connect to an IAM controller. The controller
shows any sensor in alarm and has relays for control purposes. These
controllers can be connected to each other enabling the construction of
large gas detector systems.
1.2. Applications
The IAM-100 is an ideal solution for gas detection in the following
occupied spaces:
•
•
•
•
•
hotel rooms
conference rooms
apartment blocks
office buildings
air conditioned spaces
•
•

IAM-100 and Controller Manual
Section 2.
Placing Sensors
2.1. General Guidelines
NOTE: This instrument can be equipped with a semiconductor
sensor for the detection of refrigerant, combustible and VOC
gases. Semiconductor sensors are not gas specific and respond
to a variety of other gases including propane exhaust, cleaners,
and solvents. Changes in temperature and humidity may also
affect the sensor’s performance.
The IAM-100 and optional controller (if applicable) should be positioned
carefully to avoid mechanical damage (from moving machinery, doors, etc.)
and thermal extremes (close to heaters). Units should not be placed
unprotected in direct or strong drafts/airflows and areas where water or
moisture is present unless an appropriate enclosure is used.
Avoid routing sensor cabling outside of premises, or between buildings via
overhead cables. Also, sensor wiring should be kept a minimum of 20 in (500
mm) from the main power supply and telephone cables.
When connecting the main power supply and/or sensor cables ensure a
second strain relief is used. Use a cable tie inside the enclosure within 1 in
(25mm) of the cable termination.
NOTE: The IAM-100 and optional controllers must be located
within the appropriate wire lengths from the central control unit (if
used).
In all cases the sensor supplied is designed for maximum sensitivity to a
particular gas. However, in certain circumstances false alarms may be
caused by the occasional presence of sufficiently high concentrations of
other gaseous impurities. Examples of situations where such abnormalities
may arise include the following:
•
•
•
Plant room maintenance activity involving solvent or paint fumes or
refrigerant leaks.
Accidental gas migration in fruit ripening/storage facilities
(bananas - ethylene, apples - carbon dioxide).
Heavy localized exhaust fumes (carbon monoxide, dioxide,
propane) from engine-driven forklifts in confined spaces or close to
sensors.
An optional response delay may be activated to minimize the possibilities of
false alarms.
10
6209-9000 Rev 1
IAM-100 and Controller Manual
2.2. Machinery Rooms
There is no absolute rule in determining the number of sensors and their
locations. However, a number of simple guidelines will help to make a
decision. Sensors monitor a point as opposed to an area. If the gas leak
does not reach the sensor then no alarm will be triggered. Therefore, it
is extremely important to carefully select the sensor location. Also
consider ease of access for maintenance.
The size and nature of the site will help to decide which method is the
most appropriate to use. Locations requiring the most protection in a
machinery or plant room would be around compressors, pressurized
storage vessels, refrigerant cylinders or storage rooms or pipelines. The
most common leak sources are valves, gauges, flanges, joints (brazed or
mechanical), filling or draining connections, etc.
•
•
When mechanical or natural ventilation is present, mount a
sensor in the airflow.
In machinery rooms where there is no discernible or strong
airflow then options are:
Point Detection, where sensors are located as near as
possible to the most likely sources of leakage, such as
the compressor, expansion valves, mechanical joints or
cable duct trenches.
Perimeter Detection, where sensors completely surround
the area or equipment.
•
•
•
•
For heavier-than-air gases such as halocarbon and
hydrocarbon refrigerants such as R404A, propane, and butane
sensors should be located near ground level.
For lighter-than-air gas (e.g., CH4), the sensor needs to be
located above the equipment to be monitored on a bracket or
high on a wall within 12 in (300 mm) of (or on) the ceiling –
provided there is no possibility of a thermal layer trapped under
the ceiling preventing gas from reaching the sensor.
With similar density or miscible gases, such as CO or CO2,
sensors should be mounted about head high (about 5 feet
[1.5 m]).
Sensors should be positioned just far enough back from any
high-pressure parts to allow gas clouds to form and be detected.
Otherwise, a gas leak might pass by in a high-speed jet and not
be detected by the sensor.
6209-9000 Rev 1
11
IAM-100 and Controller Manual
•
•
•
Make sure that pits, stairwells and trenches are monitored since
they may fill with stagnant pockets of gas.
If a pressure relief vent (PRV) pipe is fitted to the system, it may
be a requirement to mount a sensor to monitor this vent pipe. It
could be positioned about 6.5 ft (2 m) above the PRV to allow
gas clouds to form.
For racks or chillers pre-fitted with refrigerant sensors, these
should be mounted so as to monitor the compressors. If extract
ducts are fitted the airflow in the duct may be monitored.
2.3. Refrigerated Spaces
In refrigerated spaces, sensors should be located in the return airflow to
the evaporators on a sidewall (below head-high is preferred), or on the
ceiling, not directly in front of an evaporator. In large rooms with multiple
evaporators, sensors should be mounted on the central line between 2
adjacent evaporators, as turbulence will result in airflows mixing.
2.4. Chillers
In the case of small water- or air-cooled enclosed chiller units mount the
sensor so as to monitor airflow to the extract fans. With larger models
also place a sensor inside the enclosure under or adjacent to the
compressors.
In the case of outdoor units:
•
For enclosed air-cooled chillers or the outdoor unit for
variable refrigerant volume and variable refrigerant flow
(VRV/VRF) systems, mount the sensor so as to monitor airflow
to the extract fan. With large units also place a sensor inside the
enclosure under or adjacent to the compressors.
In the case of non-enclosed outdoor units:
•
•
•
12
If there is an enclosed machinery section then locate a sensor
there.
In the case of units with enclosed compressors, mount sensors
in the enclosures.
Where you have protective or acoustic panels mount the sensor
low down under the compressors where it is protected by the
panels.
6209-9000 Rev 1
IAM-100 and Controller Manual
•
•
With air-cooled chillers or air-cooled condensers with nonenclosed condenser sections it is difficult to effectively monitor
leaks in the coil sections. With some designs it will be possible
using an airflow sensor to monitor airflow to the start–up fans in
the front or rear sections.
If there is a possibility of refrigerant leaks into a duct or airhandling unit install a sensor to monitor the airflow.
Weatherproof sensors should be used for unprotected outdoor
applications.
2.5. Air Conditioning (Direct Systems VRF/VRV)
For compliance with EN378, at least one detector shall be installed in
each occupied space being considered and the location of detectors
shall be chosen in relation to the refrigerant and they shall be located
where the refrigerant from the leak will collect. In this case refrigerants
are heavier than air and detectors should have their sensors mounted
low, e.g., at less than bed height in the case of a hotel or other similar
Category Class A space. Ceiling voids or other voids if not sealed are
part of the occupied space.
CAUTION: Monitoring ceiling voids in a hotel room would
not strictly comply with EN378.
Do Mount In-Room Sensors…
Don’t Mount Sensors…
…at less than the normal heights of the
occupants. E.g., in a hotel room this is
less than bed height (between 8 and
20 in [200 and 500 mm] off the floor).
…under mirrors.
…away from drafts and heat sources like
radiators, etc.
…at vanity units.
… to avoid sources of steam.
…in or near bathrooms.
IMPORTANT: Carefully consider ramifications of using too few
sensors. A few extra sensors could make a significant
difference if a gas leak occurs.

4.3. Remote Sensor Head Installation
If you do not wish to surface mount the IAM or need to match room
decor, Bacharach can supply a remote sensor with a decorative
faceplate (standard finish is brushed stainless steel). The remote sensor
is mounted in an electrical back box 44mm deep to which the faceplate is
fitted.
IMPORTANT: Cleaning the decorative faceplate should be
limited to light dusting. It should not be sprayed with
cleaning/ polishing aerosols.
NOTE: For remote sensor configurations, the sensor is
mounted on a small remote sensor board that connects to
the IAM-100’s main PCB via a 4-wire connecting cable.
6209-9000 Rev 1

Step
Instructions
1
Remove the connector from the sensor PCB to feed the
cable through conduit, the IAM-100 enclosure knockouts, and
the remote sensor board back box as needed.
6209-9000 Rev 1
IAM-100 and Controller Manual
Step
Instructions
2
Immediately refit the connector to the sensor board in the
back box. The IAM-100 and its corresponding remote sensor
must be kept together as they are calibrated together and are
a matched pair.
To prevent mix-up, do not remove the sensor boards from a
number of units at the same time unless you:
• label the individual “pairs”, or
• ensure you verify that the serial number on the main
PCB and the remote sensor PCB are the same when
re-installing.
3
If construction is in process, fit a standard plastic blanking
plate immediately after you install the sensor in the back box
to avoid dust or damage to the sensor. You can fit the
faceplate when construction is completed.

Functional Tests and Calibration
6.1. Overview
NOTE: The IAM-100 is calibrated at the factory. After
installation, a zero adjustment maybe required due to
differences in environmental conditions.
IMPORTANT: If the IAM-100 is exposed to a large leak it
should be tested to ensure correct functionality, and the
sensor replaced if necessary.
To comply with the requirements of EN378 and the European F-GAS
regulation, sensors must be tested annually. However, local regulations
may specify the nature and frequency of this test.
CAUTION: Check local regulations on calibration or testing
requirements.
IMPORTANT: The testing and/or calibration of the unit must
be carried out by a suitably qualified technician, and must be
done:
•
•
in accordance with this manual
in compliance with locally applicable guidelines and
regulations.
Suitably qualified operators of the unit should be aware of the
regulations and standards set down by the industry/country
for the testing or calibration of this unit. This manual is only
intended as a guide and, insofar as permitted by law, the
manufacturer accepts no responsibility for the calibration,
testing, or operation of this unit.
The frequency and nature of testing or calibration may be
determined by local regulation or standards.
EN378 and the F-GAS Regulation require an annual check in
accordance with the manufacturer’s recommendation.

IMPORTANT:
Failure to test or calibrate the unit in
accordance with applicable instructions and with industry
guidelines may result in serious injury or death. The
manufacturer is not liable for any loss, injury, or damage
arising from improper testing, incorrect calibration, or
inappropriate use of the unit.
IMPORTANT: Bacharach recommends annual checks and
gas calibration. Calibration frequency may be extended
based on application, but should never exceed 2 years.
IMPORTANT: In applications where life safety is critical,
calibration should be done quarterly (every 3 months) or on a
more frequent basis. Bacharach is not responsible for setting
safety practices and policies. Safe work procedures including
calibration policies are best determined by company policy,
industry standards, and local codes.
There are two concepts that need to be differentiated:
Bump Test
Exposing the sensor to a gas and observing its response
to the gas. The objective is to establish if the sensor is
reacting to the gas and all the sensor outputs are working
correctly. There are two types of bump test.
• Quantified:
A known concentration of gas is
used.
• Non-Quantified: A gas of unknown concentration is
used.
Calibration
Exposing the sensor to a calibration gas, setting the “zero”
or “Standby voltage”, the span/range, and checking/
adjusting all the outputs, to ensure that they are activated
at the specified gas concentration.
NOTE: For improved accuracy and response, the instrument
should be zeroed and calibrated in the environment in which
it is being installed.

6209-9000 Rev 1
IAM-100 and Controller Manual
CAUTION: Before you perform the bump test:
•
Advise occupants, plant operators, and supervisors.
•
Check if the IAM-100 is connected to external systems
then disconnect as instructed by the customer.
•
Deactivate the alarm delay (if active) by removing the
alarm delay jumpers per Figure 7.
•
For bump test or calibration the IAM-100 should be
powered up overnight.
6.2. Bump Testing
After installation, the units should be bump tested. Expose the sensors
to test gas (R410A, CO2, etc.).
The bump test should put the system into alarm. The red LED will light
showing the system is in alarm. The delay will prevent the siren from
sounding and the relay from switching (if the delay is set).
To test the siren and or relay function, check the delay is set at zero
using the header positions 1 and 2 (as shown in Figure 7) and expose to
gas as above. You can mute the siren using the mute button.
After the gas has cleared and the red LED has switched off you can
reset the alarm relay and siren by using the reset button (if manual reset
has been selected).
Before testing the sensors on site the IAM-100 must have been powered
up and allowed to stabilize for several hours, preferably overnight.
When testing the sensors, also ensure that the IAM Controller functions
correctly (if installed) per section 6.4.
NOTE: Ideally bump tests are conducted on site in a clean
air atmosphere.
IMPORTANT: After a semiconductor sensor is exposed to a
substantial gas leak, the sensor should be checked and
replaced if necessary.
6209-9000 Rev 1
29
IAM-100 and Controller Manual
NOTE: Do not pressurize the sensor.
NOTE: You MUST use calibration gas in a balance of air
(not N2).
NOTE: Prior to carrying out a bump test, check and adjust
the zero setting. Refer to Section 6.3.

Step
Bump Testing Using Calibration Gas Cylinders
1
Remove the enclosure lid of the gas detector (not in an
exhaust area).
2
Connect a voltmeter to 0V and VS to monitor sensor
response.
3
Expose the sensor to gas from the cylinder. You can place
the entire IAM-100 into a plastic bag or use a plastic
hose/hood to direct gas to the sensor. A response of above
80% is acceptable.
6.3. Checking and Setting the Zero Setting
Checking and setting the zero setting may be required upon initial
installation.
Tools Required:
•
•
•
A voltmeter (crocodile clips are recommended)
Factory standby (zero) voltage from side label
Screwdriver
Step
Checking and Setting the Zero Setting
1
Ensure that the IAM-100 is stabilized (on for more than
24 hours)
2
Connect the voltmeter between 0V and VS.
3
Compare the reading of the voltmeter to the factory standby
voltage. Adjust P1 as necessary until the voltmeter reading
matches the factory standby voltage.

6.4. IAM Controller
If your installation has an IAM Controller, ensure that the controller’s
functions are activating accordingly when testing the sensors.
Step
32
Checking the IAM Controller
1
Red LED should illuminate for sensors that are in alarm.
2
Horn should sound if connected and if one or more alarms
are present.
3
Relays should function properly if enabled and one or more
alarms are present.
4
If enabled, remote reset will reset any downstream IAM
monitor or IAM-C connected to a channel, once gas has
cleared

Troubleshooting
Possible Cause(s)
• Check power supply. Check wiring.
• IAM was possibly damaged in transit. Check by
installing another IAM to confirm the fault.
• Sensor may be disconnected from printed circuit
board. Check to see sensor is properly inserted
into board.
• The sensor has been damaged or has reached
the end of life and needs to be exchanged.
Contact Bacharach for instructions and support.
• Try setting an alarm delay.
• Perform a bump test to ensure proper operation.
• During operation record any alarms. Establish
the cause or likely cause if no obvious leak has
occurred.
Possible Cause(s)
• Check power supply. Check wiring.
• IAM-C was possibly damaged in transit. Check
by installing another IAM-C to confirm.
• Remove the link on Jumper position HD3 as this
should be in the disabled position on a master
panel (factory default setting is disabled).
