GENERAL DESCRIPTION
The IRB-HB is a safety photo beam and may be used as an external entrapment protection device
type B1, non-contact sensor for use with automatic gates and doors. The light beam is near
infrared and pulses at a rate of 300/second (300Hz). The IRB-HB provides a signal to the gate or
door operator that the beam is not obstructed. The operating range is up to 115ft. The IRB-HB
operates over a wide range of 6-35VDC.
A green alignment indicator on the receiver provides status information at a glance, making set-up
and alignment easy.
The IRB-HB includes two selectable operating configurations providing compatibility with most
operators that accommodate monitored external entrapment protection devices per UL325-2010.
Refer to operator installation instructions for proper configuration selection:
CONFIGURATION 1 – MONITORED, HEARTBEAT 300Hz / 0Hz
Intended for use with operators designed to accept a “heartbeat” form of
monitoring, 300Hz when aligned, no obstruction, 0Hz when beam is
obstructed.
CONFIGURATION 2 – MONITORED, HEARTBEAT 300Hz / 2Hz / 0Hz
Intended for use with operators designed to accept a “heartbeat” form of
monitoring, 300Hz when aligned, no obstruction, 2Hz when beam is
obstructed, and 0Hz for a failure.
