IRM90 Motion Detector
Passive Infrared Optical Sensor
The IRM90-R is a passive infrared (PIR) motion detector is designed to provide
maximum safety and security from occupational hazards and ensure workplace
safety - even in the most hazardous and remote locations.
The detector monitors infrared radiation in the 8 to 15 micrometre range and
looks for changes in this radiation, such as an intruder walking through its 65
degree cone of vision, in order to relay an alarm. The explosion-proof housing is
factory sealed to simplify installation and the electronic circuitry does not require
any adjustments by the user. Normally closed relay contacts allow for connection
to alarm circuitry, annunciation panels or other control devices.
Certified Explosion-proof Class 1, Div 1
Normally closed relay contacts for connection to
alarm circuitry or other devices. Contacts open
when motion is detected or detector power is lost
Factory sealed enclosure eliminates the need for
conduit seals in the field
Included swivel mount simplifies installation and
makes angle adjustments fast and easy
Operating Voltage Range
24 Vdc. Device can operate between 15 and 28 Vdc
Power Consumption (24 V dc)
21 mA /510 mW nominal | 30 mA/ 720 mW maximum
Operating Temperature Range
-10°C to +50°C (+14F to +122F)
Relay Output
Normally closed relay contacts with an 18 Ohm resistor in series. Rated 24 V dc,
0.1 Amp resistive. The relay output opens when motion is detected. It reverts to
a closed state 2 to 3 seconds after motion is no longer being detected. The relay
will also open if power to the detector is lost.
Spectral Sensitivity Range
Responds to changes in infrared radiation levels between 8 to 15 micrometres
Weight (with swivel)
1.6 kg ( 3.5 lb)
Enclosure Material
Powder coated or anodized aluminum - Part # IRM90-R
(optional stainless steel - P/N IRM90-R-SS)
Certifications
Housed in a CSA, NRTL/C, NEMA 4X certified for hazardous locations Class I,
Division I, Groups B, C and D
Cone of Vision
Nominal cone of vision of 65° provided by the fresnel lens attachment.
