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. 6
