Releasing Applications
B.3.4 AHJ Abort Switch
An AHJ (Authority Having Jurisdiction) Abort Switch has a delay timer that restores the
programmed Delay Time.
When an alarm initiates in the programmed releasing zone, the programmed Delay Time starts.
Pressing and holding the abort switch suspends the delay timer. When the abort switch is released,
the control panel restores the value of the programmed Delay Time and the delay timer counts
down. When the Delay Time expires, the control panel activates releasing zone outputs.
