How to Program a Releasing Zone
Programming an IRI Abort Switch
The following contains information needed to program an IRI Abort Switch.
Description

A standard UL-type delay timer (complies with UL Standard 864) that operates like ULI, but with
additional functions for Cross Zones.

How it Works

When the first alarm occurs in a releasing zone programmed with a cross-zone code, pressing the
abort switch will prevent activation of the releasing zone should a second alarm occur while the
switch is held. When the abort switch is released, if a second alarm has occurred while the switch
was held, the ten-second IRI timer activates immediately, and the control panel activates the
releasing zone outputs at the end of the IRI timer countdown. When the abort switch is released and
a second alarm has not occurred while the switch was held, the panel waits for the cross-zone
conditions to be met before activating the releasing zone.
WARNING:
!
The IRI abort switch will only work if it is pushed before the second alarm occurs. If it is pushed after the
second alarm, the releasing zone will already have been activated, and the switch will have no effect.
Example

An IRI Abort Switch and a Delay Timer programmed to Releasing Zone R05:
Total time from when Abort
Switch is pressed to output
activation: 15 + 10 = 25
Total time from when Abort
Switch is released to output
activation: 10 seconds

Program the monitor module connected to the abort station with Type Code
detailed in "Modify an Addressable Monitor Module Point" on page 22.
Select a time for the Releasing Zone Delay Timer (refer to"Programming a Delay Timer"
on page 61.)
Do this
Type IRI in the ABORT= field, or press the next or previous keys,
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.
