2.5 Shutdown Conditions Continued
Hard Shutdown (Alarm Activated)
Note: DoorKing operators have a built-in alarm reset push buttons on the circuit board and on the bottom of the
control box for quick access. Activating either one of these buttons will return the gate operator to normal operation,
but will not activate the gate operator.
Once the gate has been reset, an open or close command is needed to start the gate operator. Most activating commands
will cause the gate operator to cycle to the open position. This includes activation of a key switch or open command and
activation of the automatic exit loop (If used). Activation of a close command will run the gate to the closed position.

A hard shutdown condition occurs when: (1.) The inherent entrapment protection system (Type A) gets activated
TWO consecutive times before the gate completes the open or close cycle. (2.) The reversing edge (Type B2) gets
activated and reverses but before the gate completes the reverse cycle the inherent entrapment protection system
(Type A) gets activated.
• Example of a Hard Shutdown - The gate is closing and the inherent entrapment protection system senses
an obstruction and causes the gate to reverse direction. As the gate begins to run in the open direction, a
second obstruction is sensed prior to the gate reaching the full open position. Once the second obstruction
has been sensed, the operator will stop, the audio alarm will sound and all standard inputs are shut
down (including open commands, safety commands, loop inputs, etc.).
– To silence the alarm, press the reset button or after 5 minutes, the audio alarm will shut off but will
“chirp” every 5 seconds. This indicates that the operator is in a hard shutdown condition (The reset
button must be pressed to reset the operator and stop the alarm “chirping”).
The operator is in a hard shutdown condition when the audio alarm is sounding OR “chirping” every 5 seconds.
• Before resetting a hard shutdown, determine why the shutdown occurred. Inspect the gate for any
obstructions along its path that could have activated the inherent entrapment sensing system. Inspect
the gate and gate hardware.
The audio alarm will sound for five minutes, or until the operator’s reset button is pushed. After (5) five minutes the
alarm will “chirp every 5 sec.” and the hard shutdown condition will remain in affect until the reset button is pushed.
