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 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). 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
8 inch
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 23. 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.
