Fail-Safe Manual Operation

The FAIL-SAFE manual operation system is the most reliable and safest method for placing an automated gate in manual operation and is the preferred method of emergency gate operation under worse case conditions by many Fire Chiefs and Building Inspectors and is typically used in CLASS I and CLASS II applications. This system requires no keys, cranks or tools for manual gate operation and is completely automatic. This prevents any delays for emergency vehicle access in the event that a power outage has occurred.

•When AC power is removed (power failure or switch power off), the operator "FAILS" in a "SAFE" condition allowing the gate to be manually pushed open without the need of any tools, keys, cranks or other devices. This assures emergency vehicle access under the worst-case conditions.

•For manual fail-safe gate operation, turn power to the operator OFF. If a backup power system is in use, be sure that this power is turned OFF also. Once power is OFF, the gate can be manually operated.

1.Pull the gate crank arm (arm that is attached to the operator shaft) away from the gate so the arms are not in a straight line.

2.Go to the end of the gate and pull it open.

Note: If an attempt is made to force the gate open under normal operating conditions (AC power present), a tamper protect circuit will detect the forced entry and will start the motor to return the gate to the closed position. If Gate Tracker reporting is in use, a forced entry attempt transaction will be sent to the DoorKing access control system at this time.
