Timer Configurations
Manual Release. The delay between the time that a manual release point activates and the
time that the suppression release points trigger. This delay cannot be aborted. (0-30 seconds;
default=10)
Detector Release Delay. The delay between the time that a detector activates and the time that
the suppression release points in L10 trigger. (0-60 seconds; default=30)
Releasing Cutout. The length of time the releasing peripheral is turned on upon alarm. (0-30
minutes; default=0 (On until Reset))
Abort Logic
The Abort switch in each hazard area is used to delay the release of suppression agents after an
automatic alarm (the Abort switch has no effect on a Manual Release). When pressed, it
usually has the effect of pausing the countdown to the release of water or chemical agents. It
must be programmed with one of the following options:
Immediate Release (No Delay). Water or chemical agents release immediately when the
Abort switch is released.
10 Second Delay. Water or chemical agents release ten seconds after the Abort switch is
released.
System Release after GREATER of Remaining Time Delay or 10 Seconds (default). Water
or chemical agents are released either 10 or x seconds after the Abort switch is released,
whichever is greatest, where x is the remaining amount of time from the number entered as the
Detector Release Delay. Example: The Detector Release Delay value is 30 seconds. The
system goes into alarm, and 15 seconds later, the Abort button is pressed. When the Abort
button is released, there will be 15 more seconds before water or chemical agents are released,
because the value of 15 is greater than 10.
IRI Abort. For dual detector applications only. If the Abort switch is pressed while one
automatic alarm is present and another alarm is activated, water or chemical agents are
released either 10 or x seconds after the Abort switch is released, whichever is greatest (See
“System Release after GREATER of Remaining Time Delay or 10 Seconds,” above). If the
Abort switch is pressed while two or more alarms are present, it has no effect. Similarly, the
Abort switch has no effect if only one alarm is present for the duration that the switch is held
down.
Reset Original Time Delay. Once the Abort switch is released, water or chemical agents are
released after the original Detector Release Delay value is counted down.
NYC. When the Abort switch is released, all RELWVIS and RELSIG NACs in the hazard area
are turned off, all RELISIG NACs are turned on, and the 90-second Investigation Timer
countdown turns on. When the Investigation Timer reaches zero, all RELWVIS and RELSIG
NACs are re-activated, all RELISIG NACs are turned off, and the Detector Release countdown
restarts from its original programmed value. Subsequently pressing and releasing the Abort
switch repeats the process. Pressing and releasing the Abort switch while the Investigation

Timer is counting down has no effect.
