How to Program a Releasing Zone Appendix A: Releasing ApplicationsNFS-640 Programming Manual P/N 51333:B 10/03/2003 57Programming an IRI Abort SwitchThe following contains information needed to program an IRI Abort Switch:Description A standard UL-type delay timer (complies with UL Standard 864) that operates likeULI, but with additional functions for Cross Zones.How to program 1. Program the monitor module connected to the abort station with Type Code ABORTSWITCH as detailed in “How to Modify an Addressable Monitor Module Point” onpage 23.2. Select a time for the Releasing Zone Delay Timer (refer to“How to Program aDelay Timer” on page 54.)3. Press at this point to save the Abort Switch value if no other fields on thescreen are changing. To change another field on the screen, move the cursor intoposition by pressing the arrow keys on the keypad.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 secondalarm occur while the switch is held. When the abort switch is released, if a secondalarm has occurred while the switch was held, the ten-second IRI timer activatesimmediately, and the control panel activates the releasing zone outputs at the end of theIRI timer countdown. When the abort switch is released and a second alarm has notoccurred while the switch was held, the panel waits for the cross-zone conditions to bemet before activating the releasing zone.WARNING: The IRI abort switch will only work if it is pushed before the secondalarm occurs. If it is pushed after the second alarm, the releasing zone will alreadyhave been activated, and the switch will have no effect.To Program Do thisIRI Abort Switch Type IRI in the ABORT= field, or press the NEXT or PREVIOUSkeys, or , until IRI appears in the field.www.PDF-Zoo.com
