INSTALLATION To prevent SERIOUS INJURY or DEATH from a moving gate: • ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. • Entrapment protection devices MUST be installed to protect anyone who may come near 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, walls, pillars, or columns. STEP 4 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 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 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 is moving, the gate will stop and reverse. The gate 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 operation in that direction will stop.
