ENTRAPMENT PROTECTION DEVICE
Non-Contact Sensors (24 Vdc Photo Electric Sensors)
NOTE: If multiple pairs of
sensors are being used, all of
the sensor wires are to be
connected in parallel at the UL
Sensor Input on the Surge
Suppressor board.
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Locate entrapment protection devices to protect in BOTH
the open and close gate cycles.
• Locate entrapment protection devices to protect between
moving gate and RIGID objects, such as posts or walls.
To reduce the risk of injury, install photo electric sensors when the gate opens to less than 18” from a wall or any other object or
potential entrapment installation. If you are going to use a non-contact sensor as a secondary entrapment protection you should use a
recognized component to comply with the revised UL 325 intended to be used in class I or class II gate operator, like the following:
LiftMaster 24 Vdc Photo Electric Sensors. Follow the installation instructions provided with the photo electric sensors for accurate
placement of the sensors. Contact your local dealer for more information about photo electric sensors.
