The Model RPC30 (-LON) Room Pressure Controller must be wired to 24 VAC only. Wiring the unit to
110 VAC will cause serious damage to the unit and void the warranty.
The pressure sensor must be mounted through the wall between the controlled space (isolation room) and
referenced space (ante room / hallway).
Go to www.tsi.com to download the Operation and Service Manual for the Model RPC30.
These installation instructions guide the installer through the installation of the TSI Model RPC30 (-LON)
PresSura Room Pressure Controller. Please read these instructions thoroughly before beginning installation.
This product is classified by UL as to fire resistive properties only. See UL File R15545.

Pressure Sensor Installation
WARNING
800243 pressure sensor must be mounted
through the wall between the controlled space
(isolation room) and referenced space
(hallway), exactly as shown in Figure 1 and
Figure 3.
Determine pressure sensor location
(Figure 1, Figure 3 and Figure 4). Pressure
sensor typically mounts in the reference
space, and the dummy housing mounts in
the isolation room.
NOTE: Pressure sensor is not symmetrical.
If sensor is to be centered over hallway
door, measure one inch to the left of center
for 2¼” hole. Dummy sensor will be 2” off
center on other side of wall.
The pressure sensor must be orientated on
the wall as shown in Figure 2. Looking at
the mounted sensor, sensor hole is on the
left (2¼”) and wire hole is on the right.
Drill a 2¼” hole through each side of the
wall to accept the sensor tube.
Drill a 78” hole on the side of the wall that
the pressure sensor will be mounted. This
hole is for the six-conductor sensor cable.
Refer to Figure 2 for a hole mounting
pattern.
Slide sensor cover to right and remove
screw that holds the sensor base to the
pressure sensor (Figure 2). Remove
pressure sensor and store in a safe place.
From the side of the wall the sensor will be
mounted, slide the sensor tube through the
wall. Mark the tube where it is flush with wall.
Remove sensor tube and cut tube 18inch
shorter than flush marking.
NOTE: If 12” sensor tube needs to be
extended, use same size or larger diameter
tube. Drill out ½” sensor hole in dummy case
to match ID of tube extension.
From the side of the wall the sensor will be
mounted, slide the sensor tube through the
wall. Slide the dummy base over the end of
the tube. Screw the pressure sensor base
and dummy base to the wall (Figure 3 and
Figure 4).
Figure 2: Pressure Sensor Orientation and
Mounting Template
Wire the pressure sensor per Figure 8 to
Figure 28. Run sensor cable to the room
pressure controller 6” 4” electrical rough-
in box.
Insert fire protection sealant (provided) into
78” wire hole to seal.
Install and screw the pressure sensor and
dummy cover onto the bases. Slide covers to
the left to hide the sensor. Finished
installation should look as shown in
Figure 4.
WARNING
Do not touch the sensor element in the
pressure sensor. Do not run wires through
the air passage. Doing so will damage the
sensing element.

Pressure Transducer Installation
WARNING
801913 pressure plates must be mounted in the
wall between the controlled space (clean room)
and referenced space (hallway), exactly as shown
in Figure 5 and Figure 6. This installation is not
representative of the through penetrating product
tested under UL.
Install pressure transducer in desired location
(typically above ceiling). The transducer must be
mounted on a wall in the correct position per
Figure 5 (screws not provided). Do not mount
pressure transducer to duct or other vibrating
surface.
Wire the pressure transducer per Figure 10 or
Figure 11. Run sensor cable to the Clean Room
Pressure Controller 6” 4” electrical rough-in box.
Determine pressure sensor location (Figure 1,
Figure 5 and Figure 6). Pressure sensor typically
mounts in the reference space, and the plate
mounts in the clean room.
Drill a 2¼-inch hole through each side of the wall
to accept the sensor tube.
Run pneumatic tubing from transducer to sensor
locations. For a positively pressurized space, the
high port should be connected to the controlled
space and the low port to the reference space.
Similarly, for a negatively pressurized space, the
low port should be connected to the controlled
space and the high to the reference space.
Connect the pneumatic tubing to the nipple on
the back side of the pressure plate.
Insert the pressure plate into the hole in the wall.
Screw the pressure plate to the wall. The finished
assembly should look like Figure 5.

Pressure Controller Installation
Pressure Controller Rough-in
Select the mounting location of the pressure controller. The construction plans normally show the
mounting location. If no location is specified, then the unit is typically installed as shown in Figure 1.
Alternate mounting locations are nurses’ station, other staff areas, etc.
Install a standard triple gang electrical box (6” 4”). The electrical box must be installed level and flush
with the wall surface.
Use appropriate firestop material, per local codes, if electrical box is to be installed in a fire barrier.
Screw PresSura DIM to electrical box (Figure 7).

Pressure Controller Wiring
WARNING
Do not connect more than 24 VAC to any terminal.
Do not apply voltage to the RS-485 output, BACnet output, analog output, or control output. Severe
damage may occur to the unit if voltage is applied.
Wiring Recommendations
TSI recommends stranded wire.
Comply with local and national electrical codes.
Follow good wiring practices:
oDo not run control wiring in the same conduit or wireway as power wiring.
oControl cables should cross power cables at a 90-degree angle.
oUse a consistent color code to maintain polarity.
oControl signals require “home run” wiring / star configuration. Do not daisy-chain control wires or
use a series configuration.
oUse daisy-chain configuration for connecting the nurses’station to monitors and controllers.
Remove the connectors from the back of the pressure controller.
Refer to the wiring diagrams, Figure 8 to Figure 28 for proper wiring installation.
If additional options need to be wired, refer to building prints for proper wiring diagram.
Plug the connectors back into the pressure controller.
Carefully push the wires into the electrical box and mount the pressure controller. Install four screws to
hold pressure controller firmly to base. Install cover and slide left to hide display.

TSI Actuator/Damper Installation
WARNING
Building prints normally determine damper location and mounting configuration. They supersede the
guidelines below.
The actuators are shipped mounted to the damper. No adjustments are needed prior to mounting
the assembly.
The damper must be installed with the damper shaft parallel to the ground (Figure 30).
Slip-fit dampers mount INSIDE the duct work. Flanged dampers bolt to the duct work. No ductwork can
be inside of dampers, or interfere with damper rotation.
Screw slip-fit damper to duct work using 1-inch or shorter screws. Make sure screws do not interfere
with damper blade rotation. Bolt flanged dampers securely to ductwork, but do not “force” damper to
fit (deforms damper).
