The major advantage of the IRB-MON is its flexibility; this photoeye covers the whole spectrum of UL situations.
Monitored application per UL325-2016 as applied to overhead door and gate operators
Non-monitored UL325 for gate operators prior to new 2016 requirements
Non-UL installation
Distributors and dealers need only one photoeye to cover all these applications.

Product Description

The IRB-MON provides a universal solution for entrapment protection. One photoeye covers the entire spectrum of possible requirements for monitored and non-monitored photo eyes, simplifying inventory management and product training. The IRB-MON is an external entrapment protection device type B1, non-contact sensor for use with automatic gates and doors. The device is UL325-2016 compliant and suitable for use with both operators that require monitored entrapment protection and those that do not require monitored operation. There are four monitoring interfaces: 1. Normally closed: Cycle power to the transmitter while monitoring the receiver contacts for proper operation 2. Two-wire pulsed (2 freq): Provides 300Hz ''heartbeat'' unobstructed, 0Hz obstructed over power supply lines 3. Two-wire pulsed (3 freq): Provides 300Hz ''heartbeat'' unobstructed, 2Hz obstructed and 0Hz failure over power supply lines 4. Resistive termination: Provides a 10k Ohm resistance when unobstructed The long range and thru-beam features combined with the installer mode switch settings provide a flexible solution to all external entrapment protection needs. A robust, NEMA 4X enclosure provides the durability required for high-reliability entrapment protection applications. Lens-less design minimizes fogging and false triggering caused by small objects and provides for easy alignment.
