To protect against accidental entrapment or injury from a
moving door it is recommended that a safety device (sensing
edge or photo eyes) be installed.
IMPORTANT INFORMATION ABOUT SAFETY DEVICES
PHOTO EYES
When properly connected and aligned, the photo eye will detect
an obstruction in the path of its invisible light beam. If an
obstruction breaks the light beam while the door is closing, the
door will stop and typically reverse to the full open position.
The photo eyes must be installed facing each other across the
door, no more than 6" (15 cm) above the floor.
SENSING EDGES
When properly connected, the sensing edge will make contact
with an obstruction while the door is closing, the door will stop
and typically reverse to the full open position.
The sensing edge must be installed on the bottom of the door.
See
Optional Safety Device Configurations
for wiring information.
