Fields Description
Abort Type
Default = None
3. IRI (Industrial Risk Insurers)
y Abort switch must be pressed before any pre-discharge begins.
y When the alarm count is reached, the pre-discharge time begins counting down to 10 seconds
and holds.
y As long as the abort switch is held, the pre-discharge timer will stop and holds at 10 seconds.
y IRI mode is a one-shot operation, but resets to 10 seconds like ULI.
y IRI is unique in that the user must press the abort switch prior to the pre-discharge timer
starting.
4. AHJ (Not UL Listed)
y Operates like ULI, except the time is set to 30 seconds when abort is pressed.
y If abort switch is pressed during the pre-discharge time and the time left is greater than (>) 30
seconds the timer will continue counting down to 30 seconds, and then stops.
y If abort switch is pressed during pre-discharge time and the time left is less than (<) 30
seconds, the timer will be set to 30 seconds and holds.
y As long as the abort switch is active, the timer will not count down.
y If the switch is released, the pre-discharge time will resume the countdown.
y Abort sequence can be repeated as many times as desired.
y Trouble is generated if the abort switch is pressed when there is no pre-discharge occurring.
Pre-Release Timer
Default = 60 seconds
Range = 0 – 60 seconds
This timer counts down prior to the release of the extinguishing agent; the timer starts when the
appropriate sensors activate the releasing function.
Pre-Release Pattern
Default = Constant
y y Specifies output pattern for general purpose NAC circuits when a pre-release timer is active.
y y Click on drop-down arrow to display options:
Constant 24VDC
ANSI/Temporal .5 sec. on, .5 sec. off, .5 sec. on, .5 sec. off, .5 sec. on, 1.5 sec. off
March Code 60 signals per minute
Double Time 120 signals per minute
Man-Release Timer
Default = 30 seconds
Range = 0 – 30 seconds This timer is used to delay the release of the extinguishing agent when the manual input is initiated.
Man-Release Abort
Allowed
Default = No
The default condition does not allow manual release to be affected by the abort. To allow manual
release to be aborted, click in the "Man-Release Abort Allowed" selection box to enter a () check
mark.
Soak Time (Minutes)
Default = 0 minutes
Range = 0 – 20 minutes This determines the solenoid activation time or amount of time the extinguishing agent is released.
