Edwards AE Bulletin, E-FSA Panel Cross Zoning

091710 September 17 2010 E FSA Panel Activation Count Cross Zoning cross zoning multiple 2 or more alarm input devices must activate before a output device will activate This can be useful when you want to be sure an has occurred a fire before action is taken activate an output For example in an lobby you may have two smoke detectors In order for the elevator control relay to and recall the elevator both smoke detectors must go into alarm With version 2.0 higher panel firmware and v3.2 or higher FSA CU configuration utility you can now cross zoning functions the Correlation section of the FSA CU there is an Activation Count window in the upper side Activation Count determines how many input devices that are part of the group must activate before all the output devices in that correlation group will If the Activation Count is 2 then two of those inputs must go into alarm before the will activate can have as many input devices be part of the correlation group as you want and have Activation Count be any number up to the number of input devices in the group If there 20 devices in the correlation group and the Activation Count is 2 then only two any two those devices must alarm for the outputs to trip If the Activation Count is 20 then all the must alarm before the outputs trip things to note An input device can be part of more than one correlation group In a alarm scenario you would have one correlation group that includes all the alarm input and all the signal circuits The Activation Count for this would be 1 any one input would trip all signals You can also have certain devices that require cross zoning as the elevator recall example The two smoke detectors in the elevator lobby would not only part of the general alarm group if either alarm all the signals would sound they would be part of a cross zoning group both must activate for the relay to trip note that when an alarm input device activates the panel will display an alarm and call central station is so equipped regardless of what the Activation Count is Activation Count controls when outputs signals relays etc are turned on Activation Count is not the as alarm verification a single smoke detector must sense smoke for an extended length time before the detector itself goes into alarm Signaling Part of UTC Fire Security 41 Woodford Ave Plainville CT 06062 800 336 4206 Web www edwardssignaling com E mail signaling techsupport fs utc com 1 of 2 the above snapshot from the FSA CU there are 2 elevator lobby smoke detectors that are of correlation group 2 upper right The Activation Count is set for 2 which means that detectors must alarm before the relay at address 10 trips lower right Signaling Part of UTC Fire Security 41 Woodford Ave Plainville CT 06062 800 336 4206 Web www edwardssignaling com E mail signaling techsupport fs utc com 2 of 2
