NOTE-1: Secondary entrapment device (UL-325)
NOTE-2: May be added as a third level of safety but is not to
replace beams marked NOTE-1
NOTE-3: Reversing edge or beam will re-open a closing gate
(use J5 #5)
NOTE-4: Stop edge will stop gate while contacted
(use JP2 connection)
NOTE: This unit to employ:
Primary entrapment is an "A1" inherent entrapment sensing
system with an audio alarm (reverses gate direction). Secondary
entrapment is a "B1" a non-contact, photoelectric beam, connect
at JP2 (stops gate, see NOTE-1). Use only UL recognized
sensors. At least one secondary "stop" photo beam should be
installed along the gate's path that is covered when open. Photo
beams are to be installed according to their manufacturer's
instructions and are to be placed in areas that pose a risk of
entrapment. A separate pedestrian door is required per UL-325.
It is recommended that all gates and operators be installed to
conform to that latest ASTM F2200-02 requirements.
