Installation
The RPM is designed to be mounted on a standard
double gang metal electrical box using a 4 × 4-inch
plaster ring adapter. Remove the cover and mount
the baseplate to the plaster ring adapter using four
6-32, 1/2-inch long mounting screws.

Figure 1. RPM Installation.
Wiring Electrical Box (Rough-In)
1.
Lay out the system in terms of wiring: power,
annunciator, analog output, BACnet, relay
output and plumbing to connect to the
monitored spaces (pressure taps).
2.
Bring all power, earth ground, signal,
communications and analog output wiring into
the 4 × 4 electrical box.
3.
Bring 1/4-inch O.D. tubing for 3/6-inch barb
fitting into box.
In order to conform to the CSA safety standard, the
electrical installer must comply with the following
earth ground instructions:
•
Pre-wire the electrical box with power
(24 Vac), and provide earth grounding to the
electrical box.
•
The safety ground path consists of four 6-32
× 1/2-inch metal screws that connect the
RPM metal base to the 4-1/2 × 4-1/2-inch
metal plaster ring. The plaster ring must be
grounded to the 4-1/2 × 4-1/2-inch electrical
box by two metal mounting screws.
•
The 4-1/2 × 4-1/2-inch electrical box must
be connected to the building earth ground. It
is also highly recommended to use armored
cable (Type AC) for all the wiring in
applications where high levels of radio
interference may be present.

•
Power leads, analog output, door status,
and annunciator wiring should be 14 to
22 AWG stranded wire.
BACnet suggested wiring is 22 AWG
stranded wire in a shielded cable, a +,-, Gnd
(S) and shield should be run. This can be
two twisted pairs with a separate cable
shield. One twisted pair is used for
communications, the second twisted pair
can be used for communications ground and
the shield wire can be connected to the
other device shield wires.

RPM Header H1
Figure 2. Plumbing Inside Electrical Box.
CAUTION:
Always attach tubing to the RPM header
and then place Header onto RPM. This will
prevent overpressure from crimped or
collapsed tubes.
Use the following procedure for all room types:
positive, negative or neutral:
Typically a Pressure Tap Plate is installed in the
monitored room. Often, stiff nylon 1/4-inch tubing is
used for running pressure signals from the RPM to
the monitored spaces. To prevent buckling and
collapse of this stiff tubing inside the electrical box,
use the supplied strain relief tubing assemblies (2) to
transition from the field tubing to the pressure fittings
on the RPM. The strain relief tubing assemblies are
an integrated system of tubing (2-1/4-inch long),
tubing nipple and over-molded spring to prevent
crimping or buckling of the tubing in the field.
Attach pressure tubing as follows:
1.
Connect the 1/4-inch O. D. tubing running from
the Tap Plate (or other pressure connection
from the monitored space) to the 4-1/2 × 4-1/2inch electrical box for the RPM.
2.
Install the barbed side of one of the strain relief
tubing assemblies onto the end of the fieldinstalled tubing.
3.
Thread the tubes through the conduit opening
at the bottom of the electrical box.
4.
Push the open end of the strain relief tubing
assembly onto the RPM pressure tube header
(H1) port labeled “+”.
NOTE:
The header is an Electro-Pneumatic
(EP) assembly. “+” indicates
(Positive) pressure, and “-” indicates
negative or reference pressure.
Item Number 129-145, Rev. EA
5. For the most pressure stable operation, a Tap
Plate installed in the reference pressure area is
also recommended. In this case, install the Tap
Plate in a hallway or reference space:
a. Attach the tube to the RPM in the same way
as for the + port, except attach the tube to
the “-” port on the pressure tube header.
b. Tighten swivel fittings on the RPM Header
H1 assembly if they become loose, 9 in lb.
max.
c.
Verify that the tubes are not buckled, which
could close off pressure signal at end of
installation.

Alarm Relay Output
The Single Pole Single Throw (SPST) relay output
can be used for remote signaling of alarm condition.
A form “C” contact rated at 1A is available. Connect
to J4, P1 and P4. This relay can be used as a dry
contact for remote indication.

Optional Remote Annunciator Wiring
NOTE: No external excitation is required.
Non-Siemens Remote Annunciator
Current Output
The RPM can drive annunciators that are powered
by a 15V supply, 50 mA max current draw, and
accept a 15V trigger. In Figure 4, the Remote
Annunciator connector is at left, and the RPM
connector is at right:
The RPM supplies its own loop power; do not wire in
a separate power supply.
3.
4.
Connect P2 to A1 (Located on Remote
Annunciator), this supplies 15V excitation to the
Annunciator for powering the circuit during
normal conditions.
Connect P3 of J4 to A2 of Remote Annunciator
J1. This is the 15V power return.
Connect P4 of RPM J4 to A3 terminal of
Remote Annunciator J1. This is the alarm
trigger.
When an alarm occurs and after the programmed
alarm delay times out the internal relay will supply
15V to the Annunciator circuit to actuate the audible
beeper and the red LED.

door jamb contact switch. The RPM will indicate
the status of door position. A contact closure
indicates that the door is closed. This is a low
voltage circuit (5 Vdc).

Door Alarm Input - Provide a “door open”
warning visual indication. When a door jamb
contact switch is used and this button is
activated by pressing Yes, the door status
“open” condition is indicated by the touch
screen display turning from green to yellow,
and door open indicated on the monitoring

•
Mute Time Out - Set the time (in seconds)
that the alarm can be silenced in the
Latched Alarm mode before the alarm
resumes. This assumes that the room static
pressure is still outside the normal or set
operating limits. The Mute Time Out can be
set from 0 to 9999 seconds.

seconds) from the time that the room
pressure goes out of the preset limits until
the alarm activates. The alarm delay may be
set from 0 to 9999 seconds.
•
Volume - Set the alarm volume or sound
level. Using the Up and Down keys, the
volume can be set at level 1 to 4. Level 4
alarm volume is the loudest and
corresponds to a sound level of 85 dB at a
distance of 4 inches.

Changing Room Alarm Modes
4.
Reconnect the electro-pneumatic Header H1
and close the cover.
If a sufficiently accurate pressure calibrator is
available, then span calibration can also be
performed. The calibration unit needs to be more
accurate than the RPM, depending on the facility’s
calibration requirements. The WC and FS columns
in the Product Numbers table on the first page of this
document the water column and full scale accuracy
of each RPM.
To calibrate the span:
The Room Pressure Monitor can be quickly changed
from Enabled monitor and alarming to Disabled (or
unoccupied). To do this, touch the room mode
indicator at the top of the pressure monitoring
screen.
Enabled/Disabled
Use these buttons to quickly change the room to
ENABLED or DISABLED status. If DISABLED is
used there will be no alarms generated if the room is
outside pressure limits.
Press Save & Exit.
Calibration Screen
1.
Open the device cover.
2.
Apply a steady full-scale pressure signal to the
+ on the header fitting and press (or tap) the
SPAN button.
3.
Reconnect the room pressure tube and
calibration is complete. Calibration must be
within ±5% of original calibration for this to
occur; otherwise, an error message will occur.
To restore the original factory pressure calibration,
press the Restore Factory Calib button.
Maintenance
The Room Pressure Monitor is designed to operate
in an indoor environment, and monitor clean, dry air.
Upon final installation of the Room Pressure
Monitor, no routine maintenance is required. A
periodic check of system calibration is
recommended, as described in the Calibration
Screen section. The unit is not field serviceable and
should be returned if repair is needed (field repair
should not be attempted and may void warranty). Be
sure to include a brief description of the problem
plus any relevant application notes. Contact
Customer Service to receive a return goods
authorization number before shipping.
Cleaning
The device is designed to operate without routine
calibration. However, it should be periodically rezeroed as follows:
1.
Open the device cover.
2.
Disconnect the electro-pneumatic Header H1
so that room pressures are not applied to the
pressure sensor.
3.
On the Calibration screen, lightly press (or tap)
the ZERO button.
Siemens Industry, Inc.
CAUTION:
Do not blow into the pressure tubing or
fittings with mouth, compressed air, or
canned air. Such actions may permanently
damage the pressure sensor.
Do not clean or wash-down the unit with
industrial cleaners or solvents. The housing
may be wiped down with soap and water or
isopropyl alcohol. The LCD may only be
cleaned with isopropyl alcohol. Do not
immerse unit.
