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,

Note: If an attempt is made to force
the gate open under NORMAL
operating conditions (AC power
present), a tamper protect circuit
(SW 1, switch 8 ON)
will detect the forced
entry and will start the
motor to return the
gate to the closed
position.
If the Gate Tracker reporting is in
use, a forced entry attempt
transaction will be sent to the
DoorKing access control system
at this time.
Manual Release
In addition to FAIL-SAFE manual operation, this operator also employs a locked release pin to place the gate in manual
operation when AC power is removed.
