Section 19 – System Operation19-13Alarm/Trouble MemoryThere are 80 memories that serve to store off-normal conditions for each input point in the system, aswell as to store system trouble conditions. Once stored in memory, the contents remain stored until theoff-normal condition has been restored to normal and a RESET command has been entered at theoperating panel. The following is a listing of the memories and an explanation of the function:Memory Type FunctionBA GroupMemoriesThere are 64 separate burglar alarm memories, eight for each BA group.Four memories of each BA group store the first four off-normal conditionsthat are detected during Day Set, and the other four memories store thefirst four off-normal conditions that occur during Nite Set. The off-normalconditions include point in alarm as well as the occurrence of a trouble,tamper, or comm-fail condition.Holdup Memory Stores the first four holdup points for which an alarm is detected.Fire Alarm Memory Stores the first four fire points for which an alarm is detected.SupervisoryMemoryStores the first four supervisory points for which an alarm is detected.Trouble Memory Stores the first four of the following events that occur:• Holdup Point - comm fail, tamper, or open lasting more than 1 minuteif using holdup suspicion option.• Fire Alarm Point - open, tamper, or comm fail condition.• Supervisory Point - open, comm fail, or tamper.• Operating Panel - comm fail.• Janitor Keyswitch Point - open, tamper, or comm fail.• BA Keyswitch Point - comm fail.• Remote Bell Point - cross, open, or comm fail. Cross indicates AC fail for4 hours; open indicates low battery.• Remote Power Supply Point - cross, open, or comm fail. Cross indicatesAC fail; open indicates low battery.If a given type of memory becomes filled, it will not store a new alarm unless one of the alarms beingstored is reset.
