B.3.3 NYC Abort Switch
An NYC Abort Switch has a standard NYC delay timer that adds 90 seconds to the programmed
Delay Time.
When an alarm initiates in the programmed releasing zone, pressing and holding the abort switch
stops the delay timer countdown. The delay timer restarts at the beginning of its countdown when
the abort switch is released. When the Delay Time expires, the 90-second NYC timer starts
counting down. When both timers expire, the control panel activates releasing zone outputs.
Example 1 - Delay Time Does Not Exceed 120 Seconds
Program a Delay Time of 15 seconds and an Abort Switch type of NYC. The releasing zone
activates and the 15-second delay timer starts. Ten seconds into the delay timer countdown, press
and hold the abort switch for 30 seconds, then release the abort switch. The control panel restarts
the delay timer at 15 seconds and adds the NYC delay of 90 seconds. The delay timers will both
expire at 105 seconds, and releasing zone outputs will begin releasing at that time. Following is a
graphic example of a NYC Abort Switch and a delay timer programmed to a releasing zone.

Example 2 - Delay Time Exceeds 120 Seconds
Program a Delay Time value of 60 seconds and an Abort Switch type of NYC. The releasing zone
activates and the 60-second delay timer starts. Ten seconds into the Delay Time countdown, press
and hold the abort switch for 30 seconds, then release the abort switch. The control panel restarts
the delay timer at 60 seconds and adds the NYC delay of 90 seconds. The delay timers will both
NOTE:
An NYC timer does not comply with UL Standard 864.
NOTE:
120 seconds is the maximum delay after the abort switch is released. If the Delay Time
plus the NYC delay time of 90 seconds exceeds 120 seconds, the releasing zone outputs will still
be activated at 120 seconds after the abort switch is released.
