Secondary Entrapment Protection Device:
In addition to the inherent reversing sensor system, the Model 6550 has a 6-pin UL 325 terminal for the connection of photo sensors-Type B1
secondary entrapment protection device required by UL 325 standards. Entrapment protection devices must be installed to reduce the risk of
injury. Install these devices where the risk of entrapment or a hazard exists while the gate is moving. Specific installations will vary.
Entrapment Protection Device Note:
Specific gate installations may require more entrapment protection
devices than are shown here. Install them where necessary to
protect against ANY potential entrapment or
hazard area.

CLOSE Entrapment Sensor (Photo Sensor):
Obstructed closing-direction
photo beam will STOP the gate during the closing-direction only. Gate will
resume the close cycle when the obstructed photo beam has been cleared.
Note: The closing-direction photo sensor typically should REVERSE the gate
when the photo beam gets obstructed. See the next page for “Reverse”
closing-direction option.
Low Voltage Common:
Common terminals for all the secondary
entrapment protection device inputs.
