SAFETY

REQUIRED ENTRAPMENT PROTECTION DEVICES

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.

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 (the

primary entrapment protection system) and REQUIRES the addition of an external

entrapment protection system (non-contact photoelectric sensor or contact safety

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.

CONTACT SENSORS (EDGE SENSORS)

If the electrically activated edge sensor comes in contact with an obstruction 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. Use edge sensor models G65MG0204, G65MGR020, or G65MGS020.

Edge Sensor for Open Cycle

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. It is best to use monitored photoelectric sensors, model CPS-UN4. 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. Unmonitored photoelectric sensor models AOMRON and RETROAB are also acceptable.

REQUIRED ENTRAPMENT PROTECTION DEVICES

• Locate entrapment protection devices to protect between moving gate and

RIGID objects, such as posts or walls.

NOTE: If the gate length exceeds the maximum distance of the photoelectric sensor beam,

then a contact edge sensor must be used.
