How to Program a Releasing Zone Appendix A: Releasing ApplicationsNFS-640 Programming Manual P/N 51333:B 10/03/2003 59Programming an NYC Abort SwitchThe 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 CodeABORT SWITCH as detailed in “How to Modify an Addressable Monitor ModulePoint” on page 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 an alarm initiates in the programmed Releasing Zone, pressing and holding theAbort switch stops the Delay Timer countdown. The Delay Timer restarts at thebeginning of its countdown when the Abort switch is released. When the Delay Timerexpires, the 90-second NYC timer starts counting down. When both timers expire, thecontrol panel activates Releasing Zone outputs.Note: 120 seconds is the maximum delay after the Abort switch is released. If the Delay Timer timeplus the NYC delay time of 90 seconds exceeds 120 seconds, Releasing Zone outputs will still beactivated at 120 seconds after the Abort switch is released.Example 1 - DelayTime Does Not Exceed120 SecondsSelect a Delay Timer value for R05 of 15 seconds. The Releasing Zone activates andthe 15-second Delay Timer starts. Ten seconds into the Delay Timer countdown, pressand hold the Abort Switch for 30 seconds, then release the Abort Switch. The controlpanel 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 willbegin releasing at that time. Following is an example of a NYC Abort Switch and aDelay Timer programmed to Releasing Zone R05:Figure 8 NYC Abort Switch Example 1To Program Do thisNYC Abort Switch Type NYC in the ABORT= field, or press the NEXT or PREVIOUSkeys, or , until NYC appears in the field.Delay=15 sec.Press and holdthe Abort SwitchWhen all timers are expired (in this example,145 seconds after alarm initiation, 105seconds after the Abort switch has beenreleased) the control panel activatesReleasing Zone outputsProgram selections for Releasing Zone R0530 sec.10 sec.Total time from alarm initiation to release:10 + 30 + 105 = 145 secondsAlarm0 sec.Release Abort Switch---At this point, the delay timebecomes the programmed delay(15 sec.) plus 90 seconds (105sec.)
