1.0 Introduction
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
flexibility.
• 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-VDC
• Unidirectional or bidirectional ranges, field selectable
