housing may be wiped down with soap and water or isopropyl alcohol; and, the
LCD display with isopropyl alcohol only. Do not immerse unit.
!
For 120/240 VAC Version, only
CAUTION: Do not open or remove SRPM cover (tool required) with
input power applied unless performed by a licensed electrician.
“Hazardous Live” voltage is present at connector J3 when power is
applied. Please observe the warning symbol ( ! ) near the J3 power
connector.

1.0 Introduction
Congratulations, and thank you for purchasing Setra’s Room Pressure Monitor
(Model SRPM). Its ease of operation and durable construction will provide years
of reliable service. While the SRPM is easy to operate, it is advisable to read this
guide carefully before use. It is designed to help you take full advantage of the
function and performance of the SRPM.
1.1 Intended Use
The SRPM is designed to monitor critical air environments, providing room static
pressure indication, alarming, and communication functions. The applications
include:
1.) hospitals - patient isolation and protection rooms, operating suites,
intensive care and emergency rooms.
2.) pharmaceutical, semiconductor, and precision
manufacturing and clean rooms.
3.) laboratories - medical research and BSLs (Bio-Safety Labs),
radiation, toxic metals and chemicals.
Green LED
Visual indication of normal room
condition
Red LED
Visual Indication of a breach in room
pressure protection.
Audible Alarm

room pressure protection
Acknowledge Switch
Press to Silence the buzzer.
1.2 SRPM Function
The SRPM senses very low differential pressure using Setra’s patented, high accuracy capacitive sensor technology. The pressure difference for these application
is the difference in static pressure between a critical environment room and its
surrounding reference area ( usually a hallway or another room) see Figure 1.
Maintaining and monitoring a static room pressure difference insures that the
critical environment room is either protected or isolated from a surrounding
environment. Protection strategy requires a net positive room static pressure
difference, while isolation requires a net negative static pressure difference. The
SRPM can be programmed to monitor either positive or negative room static
pressure. The SRPM low pressure sensing technology is coupled with multifunctional alarming and simple, intuitive touch-screen user interface with selectable
security protection.
Operation
Under normal conditions the Green LED remains on. When an alarmed condition
occurs (i.e., room pressure falls outside preset range), a signal is triggered by the
SRPM, the Green LED shuts off, the Red LED flashes and the Audible Alarm sounds.
The acknowledge button can be pressed to momentarily turn-off the Audible
Alarm and the Red LED will continue to flash until the alarmed condition is corrected. When the alarmed condition is corrected the annunciator will reset itself.
The Green LED will turn-on, the Red LED and Audible alarm will shut-off.

Installation Instructions
7.6.1 Self Test Operation
This screen identifies the Product Model and Software Version. User can also perform a Self Test of
the SRPM to verify that the data in memory hasn’t
been corrupted and also test the alarm to verify the
sound level and alarm setup.
Press “Power On Self Test” button to initiate test
sequence.
Press “Test Alarm” to test buzzer and visual Red LED
Alarm.
Press “Exit” to return to Main Menu.
7.7. CALIBRATION SCREEN
Press to Access Screen
7.7.1 Calibration
Perform a simple two-step, key tap calibration
process. To re-zero the device, disconnect the “room
pressure” tube and lightly press (or tap) the “Zero”
button. Then apply a steady full scale pressure signal
to the “+” or “room pressure” tube or fitting and
press (or tap) the “Span” button. Reconnect the room
pressure tube and calibration is complete. Calibration
must be within + or - 5% of original calibration. The
original factory pressure calibration can be restored,
if desired, by pushing the “Restore Factory Setting”
button.
22
Note: The SRPM pressure header plugs into the Setra Model 869
Expert System Calibrator for quick and secure automatic calibration. Exit to return to main menu, then press the “back key” to
enter normal monitor mode.

7.5 SETUP ALARM SCREEN
Press to Access Screen
The user can:
a.) Latched Alarm requires the pressure to return to
normal and be acknowledged before alarm can be
“Silenced” and “Reset”.
b.) Enable the audible alarm “Yes” or use visual only alarm
“No” signaling
c.) Provide a door “open” pre-alarm visual indication.
When activated the door status “open” condition is indicated by the touch screen display turning from green to
yellow, and door open indicated on Default Screen.
d.) 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 60 seconds.
e.) Set the Alarm Delay in 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 60
seconds.
f.) Set the alarm volume or sound level. Using the Up and
Down keys, the volume can bet set at level 1-4. Level 4
alarm volume is the loudest and corresponds to a sound
level of 85 db at a distance of 4 inches.

is present at connector J3 when power is applied. Please observe the warning
symbol ( ! ) near the J3 power connector.
The Setra Room Pressure Monitor is designed to be mounted on a standard
double gang metal electrical box using a 4 x 4 inch plaster ring adaptor.
Remove the SRPM cover and mount the baseplate to the plaster ring adaptor
using (4) 6-32 1/2 inch long mounting screws, see Figure 2. Note: The plaster
ring external mounting face needs to be positioned flush to recessed, relative
to the surface of the wall. Also note the orientation of the 4 mounting screws in
the plaster ring, the plaster ring is rotated 90° from conventional mounting.

metal base to the 4” x 4” metal plaster ring. The
plaster ring is grounded to the 4” x 4” electrical
box Mounting Screws (x2)

Power leads and wiring should be 14 to 22 AWG braided wire. 18 AWG braided
wire is recommended for wiring J3 power connector to SRPM (see J3, Figure 2).
For 120/240 VAC the hot wire connects to H and neutral to L.

7.3 SETUP UNIT SCREEN
3.3 Attaching Pressure Tubing
Typically a Room Pressure Snubber (RPS) is
installed in the monitored room. Attach pressure
tubing as follows:
1. ) Connect the 1/4 inch O. D. tubing (Figure 5)
from the RPS to the 4” x 4” electrical box for the
SRPM by pushing the 1/4 inch tube onto one end
of the barbed, male to male, tube adaptor, then
push the silicone tube (supplied) onto the other
end (see Figure 6). Thread the tubes, with installed
adaptor, through the conduit opening at the bottom of the electrical box (see Figure 7).
2. ) Next push the open end of the silicone tubing onto the removable SRPM header (H1), port
labeled “+”(see Figure 7).
