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.
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.
