ENTRAPMENT PROTECTION
Sensing Edge*:
(Optional) Sensing device attached to the bottom edge of the door.
Non-Contact Device*:
(Optional) Photo eye device.
* Per the requirements of UL Standard 325, the door operator is setup for constant pressure
to close the door. As an alternative, the door may be provided with a monitored entrapment
protection device that will reverse the door upon contact with or detection of an obstruction
during closing. Adding an entrapment device would enable momentary close operation.
*Note:
1. Non-contact device (photo eye) can be used on doors up to 45 ft. wide (or maximum rated range of
device if less than 45 ft.). Use a sensing edge to provide entrapment protection on doors over 45 ft.
wide.
2. Sensing edge can be used on all doors.
