  Return MODEL IRB-MON - Universal Safety Photo Beam
UL-325-2016 NEMA 4X
The IRB-MON is a monitored, weatherproof, thru-beam infrared photoeye, that is the perfect solution to providing entrapment protection for doors, gates, and barriers. The IRB-MON photo beam is UL325-2016 compliant and housed in a robust NEMA 4X enclosure that is rated for indoor or outdoor applications. The universal design allows this product to be used with an array of monitored operators, and is compatible with most non-monitored legacy operators/openers.

The IRB-MON provides 4 monitoring interfaces:

  1. Normally Closed
  2. Two-Wire Pulsed (2 Frequency)
  3. Two-Wire Pulsed (3 Frequency)
  4. 10K Resistive Termination

The IRB-MON is considered universal because it addresses a wide variety of external entrapment protection thanks to it's long range, thru beam detection technology and selectable frequency feature.


  • Easy to install and set-up thanks to 2-wire connection and 24 detection angle
  • Rugged NEMA-4X enclosure
  • Features lens-less design to minimize fogging and false triggering
  • Operating range up to 115' (35m)
  • UL325-2016 Compliant
  • Selectable frequency modes
