MODEL 800243 or 800326
THROUGH-THE-WALL ROOM PRESSURE SENSOR
INSTALLATION INSTRUCTIONS
WARNING
THE MODEL 800243/800326 ROOM PRESSURE SENSORS 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 and referenced space.
These installation instructions guide the installer through the installation of the TSI Model 800243/800326
Through-the-Wall Room Pressure Sensor. Unless specified otherwise, figures and instructions apply to all
versions. 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
800243/800326 pressure sensor must be
mounted through-the-wall between the
controlled space (isolation room) and referenced
space (hallway), exactly as shown in Figure 3
and Figure 4.
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).Mod 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.
Figure 2: Pressure Sensor Orientation and
Mounting Template
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).
Wire the pressure sensor per Figure 5. Run
sensor cable to the room pressure monitor
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.

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.
Refer to the wiring diagram, Figure 5 for proper wiring installation.
Power Requirements
Through the Wall Sensor Each
24 VAC, 50/60 Hz, 3VA
WARNING
Sensor must be wired exactly as wire diagram shows. Making modifications to the wiring may severely
damage the unit. See monitor or controller installation instructions for complete wiring diagrams.
