This allows delay of the alarm up to 180 seconds after the start of alarmprocessing. The control panel Presignal feature provides two selections:1RWH 3UHVLJQDO GLIIHUV IURP WKH$ODUP 9HULILFDWLRQ 7LPHU ZKLFKGRHV QRW UHTXLUH KXPDQLQWHUYHQWLRQ• A Presignal Delay Timer (60-180 seconds) that delays activation of all outputswith a CBE that includes Special Zone F0.• A PAS (Positive Alarm Sequence) selection, in addition to the Presignal DelayTimer, that allows a 15-second time period for acknowledging an alarm signalfrom a fire detection/initiating device. If the alarm is not acknowledged within 15seconds, all local and remote outputs activate immediately and automatically.Figure 78 contains an illustration of Presignal and PAS timing.)LJXUH 3UHVLJQDO DQG 3$6 7LPHThe control panel delays activation of outputs containing F0 in their Control-By-Event(CBE) list for all alarm initiating devices that contain F0 in their CBE list. A subsequentalarm will abort the Presignal Delay Timer and execute CBE lists.1RWHV RQ XVLQJ ) • NFPA 72 requires installation of a PAS Inhibit switch, that you can use to turn offthe PAS delay timer when the control panel is unattended. Do so by programming amonitor module with the Type Code, PAS INHIBIT . For details, refer to "How toProgram a Monitor Module" on page 23.• Abort circuit activation by pressing the ALARM SILENCE key before the PresignalDelay Timer expires.• Program zone F0 to participating inputs and outputs.5HVWULFWLRQV RQ XVLQJ ) • Do not include F0 in the CBE list for a releasing device.• Do not include F0 in the CBE list for any monitor module that connects to a deviceother than an automatic fire detector.Continued on the next page...3UHVLJQDO 'HOD\ 7LPHU V3$6 V,QLWLDO DODUPDQQXQFLDWLRQ$ODUP DFWLYDWHV RXWSXWV LI WKHFRQWURO SDQHO LV QRW UHVHW,I 3$6 < DODUP DFWLYDWHVRXWSXWV LI QRW DFNQRZOHGJHGTechnical Manuals Online! - http://www.tech-man.com
