UL 325 COMPLIANT SENSORS
Recommended External Entrapment Protection Sensors List for FoldSmart
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)
Swing Gates: To enable fully automatic operation, all SWING gate operators will require a minimum of
ONE monitored external entrapment protection sensor to protect entrapment zones in either the open
or close direction of travel. However, an additional monitored sensor is required if there is a risk of
entrapment in both directions of gate travel.
Preferred solution for swing gates: A photo eye for the close direction and/or a hard-wired wraparound
edge sensor on the leading edge of the gate, which protects for both directions of gate travel.
Installers must assess each specific site and install sensors that protect all potential entrapment zones.
See figure below; EYE CLOSE is programmed at the appropriate sensor input (1, 2 or 3). Refer also to
“Figure 28-1. Photo Eye Placement for External Entrapment Protection” on page 116
, and Figures 28-2
to 28-5.
