Programming an AHJ Abort Switch
The following contains information needed to program an AHJ Abort Switch:
Description An AHJ (Authority Having Jurisdiction) delay timer that restores the programmed Delay Timer.
Note: An AHJ timer does not comply with UL Standard 864.
How to program 1. Program the monitor module connected to the abort station with the Type Code
ABORT
SWITCH as detailed in “How to Modify an Addressable Monitor Module Point” on page
23.
2. Select a time for the Releasing Zone Delay Timer (refer to“How to Program a Delay
Timer” on page 54.)
3. Press at this point to save the Abort Switch value if no other fields on the
screen are changing. To change another field on the screen, move the cursor into
position by pressing the arrow keys on the keypad.
How it works When an alarm initiates, the programmed Delay Timer starts. Press and hold the Abort
switch and the control panel suspends the Delay Timer. When you release the Abort Switch,
the control panel restores the value of the programmed Delay Timer and the Delay Timer
counts down. When the Delay Timer expires, the control panel activates Releasing Zone
outputs.
