Abort Switches Releasing Applications
NFS-3030 Programming Manual P/N 51345:C 11/4/03 85
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 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 a graphic example of an
NYC Abort Switch and a delay timer programmed to a releasing zone.
Appendix Figure B-7 NYC Abort Switch -Example 2
Delay Time: 60 seconds
Abort Switch: NYC
Cross Zone: N
Soak Time: 0
Program selections for this releasing zone
Delay Time=60 sec.
Press and hold
the Abort Switch
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.
30 sec.
10 sec.
120 sec. to release
Total time from alarm initiation to release:
10 + 30 + 60 + 60 = 160 seconds
Alarm
0 sec.
NYC Delay=90 sec.
Release Abort Switch---
At this point, the delay becomes the
programmed Delay Time (60
seconds) plus the NYC Delay (90
seconds), which is 150 seconds, OR
120 seconds, whichever is smaller.
Pressing and releasing abort switch
restarts Delay Time=60 countdown after
40 seconds have elapsed.
Delay=60 sec.
150 sec. (60 + 90). Exceeds 120 seconds.
