Install Entrapment Protection

Page 13 highlights

INSTALLATION To prevent SERIOUS INJURY or DEATH from a moving gate/door: • Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate/door. • Locate entrapment protection devices to protect in BOTH the open and close gate/door cycles. • Locate entrapment protection devices to protect between moving gate/door and RIGID objects, such as posts or walls. STEP 5 INSTALL ENTRAPMENT PROTECTION This operator contains an inherent (internal) entrapment protection system and REQUIRES the addition of an external monitored entrapment protection system (non-contact photoelectric sensor or contact edge sensor) for EACH entrapment zone prior to gate/door movement. A monitored device sends a pulsed signal to the operator so the operator is aware of the device. If the operator does not receive the signal from the device it will not run. An entrapment zone is every location or point of contact where a person can become entrapped between a moving gate/door and a stationary object. Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly. Use only LiftMaster approved entrapment protection devices (refer to the accessory page). NON-CONTACT SENSORS If the photoelectric sensor beam gets blocked while the gate/door is moving, the gate/door will stop or reverse. The gate/door will not be able to travel in that direction until the obstruction is cleared. Monitored photoelectric sensors MUST be used. If a monitored photoelectric sensor is not working or loses power or the beam is blocked, then ALL gate/door operation in that direction will stop. CONTACT SENSORS (EDGE SENSORS) If the electrically activated edge sensor comes in contact with an obstruction while the gate/door is moving, the gate/door will stop or reverse. The gate/door will not be able to travel in that direction until the obstruction is cleared. 13

To prevent SERIOUS INJURY or DEATH from a moving gate/door:
Entrapment protection devices MUST be installed to protect anyone
who may come near a moving gate/door.
Locate entrapment protection devices to protect in BOTH the open
and close gate/door cycles.
Locate entrapment protection devices to protect between moving
gate/door and RIGID objects, such as posts or walls.
STEP 5
INSTALL ENTRAPMENT PROTECTION
This operator contains an inherent (internal) entrapment protection system and REQUIRES the addition of an external monitored entrapment
protection system (non-contact photoelectric sensor or contact edge sensor) for EACH entrapment zone prior to gate/door movement.
A monitored
device sends a pulsed signal to the operator so the operator is aware of the device. If the operator does not receive the signal from the device it will
not run.
An entrapment zone is every location or point of contact where a person can become entrapped between a moving gate/door and a stationary object.
Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly. Use only
LiftMaster approved entrapment protection devices (refer to the accessory page).
INSTALLATION
CONTACT SENSORS (EDGE SENSORS)
If the electrically activated edge sensor comes in contact with an obstruction while the gate/door is moving, the gate/door will stop or reverse. The
gate/door will not be able to travel in that direction until the obstruction is cleared.
NON-CONTACT SENSORS
If the photoelectric sensor beam gets blocked while the gate/door is moving, the gate/door will stop or reverse. The gate/door will not be able to travel
in that direction until the obstruction is cleared. Monitored photoelectric sensors MUST be used. If a monitored photoelectric sensor is not working or
loses power or the beam is blocked, then ALL gate/door operation in that direction will stop.
