Programming an NYC Abort Switch
The following contains information needed to program an NYC Abort Switch:
Description A standard NYC delay timer that adds 90 seconds to the programmed Delay Timer.
Note: An NYC 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 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 Timer
expires, the 90-second NYC timer starts counting down. When both timers expire, the
control panel activates Releasing Zone outputs.
Note: 120 seconds is the maximum delay after the Abort switch is released. If the Delay Timer time
plus the NYC delay time of 90 seconds exceeds 120 seconds, Releasing Zone outputs will still be
activated at 120 seconds after the Abort switch is released.
Example 1 - Delay
Time Does Not Exceed
120 Seconds
Select a Delay Timer value for R05 of 15 seconds. 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 an example of a NYC Abort Switch and a
Delay Timer programmed to Releasing Zone R05:

To Program Do this
NYC Abort Switch Type NYC in the ABORT= field, or press the
NEXT or PREVIOUS
keys, or , until NYC appears in the field.
Delay=15 sec.
Press and hold
the Abort Switch
When all timers are expired (in this example,
145 seconds after alarm initiation, 105
seconds after the Abort switch has been
released) the control panel activates
Releasing Zone outputs
Program selections for Releasing Zone R05

10 sec.
Total time from alarm initiation to release:
10 + 30 + 105 = 145 seconds

At this point, the delay time
becomes the programmed delay
(15 sec.) plus 90 seconds (105
sec.) OR 120 seconds,
whichever is smaller
