1.0 FEATURES
The SRIM1 has a non backlit LCD display and alarms on pressure. It is capable of true 2 wire 4-
20 mA loop powered operation.
The SRIM2 is a 3 wire has a 3 color backlight, a digital input for a door switch, 2 analog inputs for temperature and humidity and 1 relay output for remote alarm indication. It can alarm on
Pressure, temperature and humidity parameters.
Monitor Room Parameters
Room Pressure Temperature Humidity Door status (Open or closed)
User Interface
Large LCD 2 line display, Room Pressure, Temperature (Optional) and Humidity
(Optional) as well as room status indication.
Green (Normal), Yellow (Warning), Red (Alarm) Backlit display for indicating the room
status for SRIM2, Monochrome for SRIM1
Membrane keypad for ease of configuration and menu navigation. Password Protection for security.
Audible Visual and Remote Alarms
Color Backlight LEDs. Alarm on Pressure, temperature and humidity Audible Buzzer. Alarm delay, mute timeout, alarm enable/disable, buzzer enable/disable SPDT Relay for remote alarms, including Setra Remote Annunciator (SRAN).
Ease of Installation Use and Calibration
Flush mount and duct mount versions, both wipe down for decontamination. Rotate-able pressure fittings to eliminate crimping of pressures hoses, allows installation
flexability.
Snap on cover, no visible fasteners. Modular Plug in design using sub-base. Simultaneous Electrical and plumbing
connections reduce initial installation and calibration costs. Unit can be calibrated in
house or sent to Calibration service without removing the wiring or plumbing.
Push button zero and span calibration, no potentiometer adjustments. PG9 and Conduit fitting in same unit, field selectable.
Versatile
Field selectable outputs, 4-20 ma. 0-5 VDC and 0-10 VDC
Uni Directional or Bi Directional Ranges, field selectable

Intended Use
The Setra SRIM Room Isolation Pressure Monitor is designed for critical low differential pressure applications that require stringent pressure monitoring and alarming. The SRIM can be configured to monitor positive, negative or neutral pressures in protected environments. The SRIM is a complete system that includes a 2 line LCD display with large characters for the pressure, temperature and humidity indication and room status. The membrane keypad user interface enables access to setup, security, calibration, and alarm setups. Backlight LED's (SRIM2) provide a local visual indication of the room pressure alarm status and a local audible alarm (with time delay feature) alert personnel to system status. Analog outputs are available in 4-20 mA, 0-5 or 0-10 VDC in the same unit. True differential pressure is displayed with a resolution of up to .0001” as well as the room status. Setra’s patented very low pressure capacitance sensor is dead ended and avoids the potential for cross contamination of the room and reference space as well as eliminating drift that results from fouling of flow based sensors, which by nature have
a flow path connecting the protected and reference spaces.
2.0 SRIM INCLUDED PARTS
Fig. 2-1 Parts
The SRIM parts list includes SRIM Isolation Room Monitor Electrical Plugs for ½” conduit or PG9 strain relief connector.
RPS pressure taps 0, 1 or 2 as ordered, including mounting screws. The RPS is mounted to a single gang box. One is typically located in the isolation room and the second is mounted in a corridor (reference pressure). The back of the RPS has a barbed fitting for plastic tubing to be
connected to the SRIM.

3.0 INSTALLATION
The SRIM is available in two models suitable for wall (flush mount) and surface
mounting (or panel mounting). The front panel of the product and product rear housing are snapped together, the two snaps are located on the left and right sides of the front panel. A
1.5mm1/16 inchAllen wrench or paper clip can be used to open the concealed snap fastening system. The rear housing can be used to mount to a wall or into a 3 gang “off the shelf” electrical box. Conduit (1/2”) or a PG9 cable connection are available for wiring to the terminals at the rear of the unit. The rear housing acts much like a sub-base that does not have to be removed once installed. The front bezel contains the pressure sensor, PCBA and display. It is a complete module that can be calibrated. The pressure and electrical connectors are disconnected simultaneously when the front bezel is removed.
Before installing determine a good installation location. For Flush mount applications, the corridor outside the isolation room is preferred. For Surface mount applications the unit may be mounted on the duct work (avoid high vibration), a stable surface near the ductwork or inside a
panel.

Unpack the product box. Do not remove the protective film on the front panel until after
installation to prevent scratching of the display during the installation process. Remove parts and
place them on flat surface. Apply pressure on the side of the box to open the snap fit or use an allen wrench or paper clip as shown See Figure 1-2. First one side then the other, then pull the
bezel forward to remove it from the housing

Plumbing and Wiring to the Electrical Box (Rough in)
Flush mounting:
Use a 3 gang electrical box RACO 697 or equivalent or mount directly into the wall. If mounting directly into the wall create an opening approximately 2.8” (71 mm) by 5.4” (134 mm). If using the 3 gang box use #6 machine screws to mount the ears of the SRIM rear housing to the electrical box. If mounting directly into the wall without an electrical box, use drywall screws to mount the
4 ears of the SRIM box to the wall.
