1.9 Entrapment Protection Installation
CLOSE Beam: Obstructed close-direction photo beam will REVERSE the gate
during the close-direction only. Gate will close when the obstructed photo
beam has been cleared and the close-timer times out.
OPEN Beam: Obstructed open-direction photo beam will STOP the gate during
the open-direction only. Gate will resume the open cycle when the obstructed
photo beam has been cleared.
See page 28 for UL 325
terminal wiring for a
monitored photo sensor.

Entrapment protection
is RECOMMENDED for
this area.
If the distance between an entrapment or obstruction
exists less than 16” from the open gate, then
entrapment protection is REQUIRED for this area.
External Entrapment Protection Devices:
In addition to the inherent reversing sensor system, this operator has a UL 325 terminal for the connection of photo sensors-Type B1 and/or
reversing edges-Type B2 entrapment protection required by UL 325 standards. Entrapment Protection must be provided for the gate system
where the risk of entrapment or obstruction exists. The operator will NOT run without one or more monitored type B1 or B2 external
entrapment protection devices installed in each entrapment area. Install these devices where the risk of entrapment or a safety hazard
exists, examples of which are shown below and next page. Installations can vary.
