The IRB-MON is a monitored, weather-proof, thru-beam infrared photo eye solution providing entrapment protection for doors, gates and barriers. The IRB-MON Safety Photo Beam is UL325 compliant, and housed in a rugged NEMA 4X enclosure. It is designed to meet the upcoming 2016 UL325 regulation.

The universal design of the IRB-MON allows it to be used with operator types that require a frequency (heartbeat) for monitored operation or those that require relay connections. Monitored output is achieved by using the "heartbeat" output from the IRB-MON to assure that the connections to the photo eye are intact and that the photo eye is operational.

Monitored output may also be achieved using the relay contacts, cycling power of the transmitter and verifying the contact closure at the receiver before the actuation of the operator.

Non-monitored output is provided by a set of form C relay contacts.

The IRB-MON addresses a wide variety of external entrapment protection needs due to its long range, thru beam detection technology and selectable frequency feature.
