Abort Switches Releasing Applications
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.

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.
