Select a Delay Timer value for R05 of 60 seconds. The Releasing Zone activates and
the 60-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 60 seconds and adds the NYC delay of 90 seconds.
The delay timers will both expire at 150 seconds: however, this time exceeds the
maximum of 120 seconds, so the Releasing Zone outputs will begin releasing at 120
seconds, not at 150. Following is an example of a NYC Abort Switch and a Delay
Timer programmed to Releasing Zone R05:
PRG RELEASE FUNCTION RELEASE CONTROL
DELAY=60 ABORT=NYC CROSS=N SOK=0000
Program selections for Releasing Zone R05
Delay=60 sec.
Pressing and releasing Abort switch
restarts Delay=60 countdown after
40 seconds have elapsed.

At this point, the delay becomes
the balance of the programmed
delay (60 sec.) plus 90 seconds
(150 sec.) OR 120 seconds,
whichever is smaller

Total time from alarm initiation to release:
10 + 30 + 60 + 60 = 150 seconds
Delay=60 sec.
NYC Delay=90 sec.
150 sec. (60 + 90). Exceeds 120 seconds.
120 sec. to release
The control panel activates
Releasing Zone outputs after
120 seconds have elapsed.
The NYC timer has not
expired, but it is overridden by
the control panel.
