Installation and Operation Manual
programmed as latched. Returning to normal condition will cause the supervisory event to disappear when it is
programmed as non‐latched.
When the supervisory condition has occurred, pressing ACKNOWLEDGE button will silence the buzzer and
change the supervisory LED to steady ON.
If the panel is configured for Supv/Trouble Resound Reminder, when the supervisory condition is not corrected
and the Supv/Trouble Resound Reminder timer has elapsed, the panel will re‐annunciate the supervisory
condition.
Device, Appliance Handling
NAC Activation and Silence
The notification appliance circuits are controlled by a microprocessor to provide more versatility than in a total
hardware system.
Output Sounding Patterns ‐ Notification appliance circuits are operable in Temporal‐3 pattern.
Alarm Silence Inhibit ‐ Control panel may be programmed to inhibit Alarm Silence from 0 to 20minutes from
the last alarm.
All of the NACs are power limited and support synchronization of the listed devices.
The open, short, and grounding troubles of notification appliance circuit are monitored.
Device Supervision
Device type supervision: If the type reported by an addressable detector or module does not agree with the
configuration, the system reports a trouble condition.
Device address supervision: The system checks that the configured devices on the Addressable Device Circuit
and the Serial Interface Circuit respond to an address poll. The system reports a trouble condition if one of the
following conditions is detected:
• Configured device is missing.
• Unconfigured device is installed.
• Two or more devices are programmed with the same address location (this trouble is only detected by
manually checking).
Detector Monitor
The control panel processor polls the detectors for their status. The detector determines normal, trouble, and
alarm conditions and communicates the status to the control panel.
The control panel can automatically trigger an alarm or a trouble for various conditions, including:
Active
Illegal
Wrong Type
Missing
Address Conflict
