UL 325 COMPLIANT SENSORS
Recommended External Entrapment Protection Sensors List for the SmartDC Controller – Kinetic Operator
Excerpts from UL 325 Standard:
The operator shall monitor for the presence of every device at least once during each open and close
cycle. (Clause 32.1.8 of the Standard)
It shall not be possible to make simple modifications in the field by adding, suppressing or changing, either
on the operator or external entrapment protection device(s), to bypass, interfere with, or otherwise
defeat the monitoring function. (Clause 32.1.10 of the Standard)
Entrapment zones are now defined for each gate type. (Clauses 4.23, 4.24, 4.29, 4.34 of the Standard)
Slide Gates: To enable fully automatic operation, all SLIDE gate operators will require a minimum of TWO
monitored external entrapment protection sensors (one for each direction) to protect entrapment zones
in both the open and close direction of travel.
Preferred solution for slide gates: A photo eye for the close direction and a hard-wired edge sensor for
the open direction that is mounted to the face of the leading post of the fence behind the gate. (Reach-
through injuries are the most common hazard associated with automatic sliding gates).
Installers must assess each specific site and install sensors that protect all potential entrapment zones.
See figure below; EYE CLOSE and EDGE OPEN are programmed at the appropriate sensor inputs (1, 2 or 3).
