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.

• Locate entrapment protection devices to protect between moving gate and

RIGID objects, such as posts or walls.

SAFETY

REQUIRED ENTRAPMENT PROTECTION DEVICES

REQUIRED ENTRAPMENT PROTECTION DEVICES

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

Edge Sensor for Close 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.
