These include:• Maintenance alert• Pre-alarm alert• No response• Incorrect responseOther System Sensor Addressable DevicesHeat SensorsCompatible heat sensing addressable devices may be intermixed on the circuit for locations where heatsensing may be the most effective detection mode.Addressable Modules (Monitor and Control)In addition to sensors, the circuit can communicate with addressable modules, allowing initiating devicesor notification appliances with local power sources, and supervising the power sources.Manual StationsSingle and dual-stage manual stations with monitor modules may be intermixed on the circuit with properresponse programmed into the control unit. For fastest response, manual stations should be connectedso that their address is 1-9.PROCESSOR CONTROLLED OUTPUT ZONESWhile the notification appliance circuits are essentially hardware circuits, the fact that the outputs arecommanded and controlled by the processor does provide more versatility than in a total hardwaresystem. All functional selections are included in the control unit programming process.Output Sounding PatternsThe notification appliance circuits are operable in different sounding patterns. Any circuit is selectable toany of eight software-generated patterns or continuous sounding. For convenience, three of the patternsare preprogrammed for March Time, Temporal, and Californian patterns.Control of Audible SilencingIt is possible to select an “auto-silence” mode, adjustable from 0 to 255 minutes. Each notificationappliance circuit programmed for alarm silence sequence, will be silenced upon time-out of the auto-silence timer. The alarm silenced LED will flash, indicating the auto-silence time-out.Audible Silence InhibitIn addition to designation of waterflow zones, the entire control unit may be programmed to inhibit audiblesilence for 0, 1, 3, or 6 minutes from the last alarm. System reset may also be inhibited.
