Operator Alerts
The control unit can trigger an alarm or trouble automatically on the occurrence of a number of conditions
of the sensor devices. These include:
•
Maintenance alert
•
Pre-alarm alert
•
No response
•
Incorrect response
Other System Sensor Addressable Devices
Heat Sensors
Compatible heat sensing addressable devices may be intermixed on the circuit for locations where heat
sensing 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 devices
or notification appliances with local power sources, and supervising the power sources.
Manual Stations
Single and dual-stage manual stations with monitor modules may be intermixed on the circuit with proper
response programmed into the control unit. For fastest response, manual stations should be connected
so that their address is 1-9.
PROCESSOR CONTROLLED OUTPUT ZONES
While the notification appliance circuits are essentially hardware circuits, the fact that the outputs are
commanded and controlled by the processor does provide more versatility than in a total hardware
system. All functional selections are included in the control unit programming process.
Output Sounding Patterns
The notification appliance circuits are operable in different sounding patterns. Any circuit is selectable to
any of eight software-generated patterns or continuous sounding. For convenience, three of the patterns
are preprogrammed for March Time, Temporal, and Californian patterns.
Control of Audible Silencing
It is possible to select an “auto-silence” mode, adjustable from 0 to 255 minutes. Each notification
appliance 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 Inhibit
In addition to designation of waterflow zones, the entire control unit may be programmed to inhibit audible
silence for 0, 1, 3, or 6 minutes from the last alarm. System reset may also be inhibited.
