MODEL 8630 PRESSURA™
ROOM PRESSURE MONITOR
INSTALLATION INSTRUCTIONS
WARNING: The Model 8630 Room Pressure Monitor 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).
These installation instructions guide the installer through the installation of the TSI Model 8630 PresSura™
Room Pressure Monitor. Please read these instructions thoroughly before beginning installation.
This product is classified by Underwriters Laboratories, Inc.®for use in through-penetration
firestop systems. See UL fire resistance directory.

Pressure Sensor Installation
Figure 2: Pressure Sensor Orientation and Mounting Template
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 2 and 3.
1. Determine pressure sensor location
(Figures 1, 2 and 3). 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.
2. 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.
3. Drill a 2¼-inch hole through each side of
the wall to accept the sensor tube.
4. Drill a 7/8-inch 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.
5. 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.

6. 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.
7. 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).
8. Wire the pressure sensor per Figure 7. Run
sensor cable to the room pressure monitor
4” x4” electrical rough-in box.
9. Insert fire protection sealant (provided)
into 7/8” wire hole to seal.
10. 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.

Transformer Installation
Figure 5: Transformer Installation
WARNING
Make sure no power is applied
until all wiring is complete.
Follow all applicable electrical
codes, and have qualified
personnel install the
transformer.
Note: Each system must be
installed with supplied
transformer. If TSI
transformer is discarded
and a central transformer
is installed, a separate
isolation transformer
must be installed in line
between the TSI system
and central transformer.
1. Mount a standard 4" x4" x1½" electrical box at a convenient location within 20 feet of
pressure monitor.
2. Run 115 Volt, single phase, 60 hertz line voltage (115 VAC) to electrical box. Follow all
applicable electrical codes.
3. Connect 115 VAC line voltage HOT wire to BLACK wire on transformer and NEUTRAL wire to
WHITE wire on transformer (Figure 5).
4. Connect the RED wire on 800414 transformer cable to either of the YELLOW wires on the
transformer and the BLACK wire to the remaining YELLOW wire.
5. Screw the transformer to the electrical box.
6. Run transformer cable from the transformer electrical box to the pressure monitor. Have at
least 8 inches of cable coming out of the pressure monitor rough in electrical box before
trimming cable to length.

Pressure Monitor Installation
Pressure Monitor Rough-in
1. Select the mounting location of the pressure monitor. 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 nurse’s station, other staff areas, etc.
2. Install a standard double gang electrical box (4” x4”).
3. Slide the pressure monitor cover to the right and remove three screws holding the electronics
to the base (Figure 6). Remove base.
4. Install the base to the 4” x4” electrical box. The base’s “THIS SIDE UP” arrow must be pointing
towards the ceiling.
Figure 6: Pressure Monitor Mounting
Note: Two screws are hidden behind the cover
when full open. The cover will slide to the
right approximately 2 inches until a stop
is hit. Pull cover to completely remove
from electronics and expose the screws.
Pressure Monitor Wiring
WARNING: Do not connect more than 24 VAC to any terminal.
Do not apply voltage to the RS-485 output, analog output, or control output. Severe
damage may occur to the unit if voltage is applied.
1. Remove the connectors from the back of the pressure monitor.
2. Refer to the wiring diagram (Figure 7) for proper wiring installation.
3. If additional options need to be wired, refer to building prints for proper wiring diagram.
4. Plug the connectors back into the pressure monitor.
5. Carefully push the wires into the electrical box and mount the pressure monitor. Install three
screws to hold pressure monitor firmly to base. Install cover and slide left to hide display.
