This feature provides a method of maintaining fire strobes after the alarm bells are silenced, and is also called the Audible Silence Feature.
7000/9000 and G series control panels with Eprom revision 6.80 and later and Eprom revision 7.01 and earlier on the GV2 Series control panels offer the ability to latch the Summary Fire Alarm Relay. Enter a 24 in Area 2 Silent Alarm Relay. When the Silent Alarm Relay for Area 2 is programmed with 24, the Summary Fire Alarm Relay remains active until all fire alarms are cleared from the keypad display.
The default operation is consistent with the Summary Fire Relay operation in Version 6.60 and earlier for the D7000/9000 and G Series control panels. For Eprom revision 7.03 and earlier for the GV2 Series control panels, the relay follows the point.
Example: As long as the point is shorted, the relay is active. Remove the short and the relay de-energizes.
