Install Entrapment Protection - Chamberlain LA500 Installation Manual

To prevent SERIOUS INJURY or DEATH from a moving gate:
• 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.
STEP 7

INSTALL ENTRAPMENT PROTECTION

At least one external monitored entrapment protection device is required prior to gate movement (effective January of 2016). 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. All
gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. This operator contains an inherent
(internal) entrapment protection system and REQUIRES the addition of an external entrapment protection system (non-contact photoelectric sensor or
contact edge sensor) for EACH entrapment zone.
Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly.
NON-CONTACT SENSORS
If the photoelectric sensor beam gets blocked while the gate is moving, the gate will stop and reverse for 4 seconds. The gate will not be able to travel
in that direction until the obstruction is cleared. CPS-UN4 or CPS-RPEN4GM 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.
Sensors for Open Cycle
NOTE: If the distance
between the open gate
and the wall is less than
16" (40.6 cm) entrapment
protection for this area is
required.
INSTALLATION
• Locate entrapment protection devices to protect between moving
gate and RIGID objects, such as posts or walls.
