Control-By-Event (CBE)Operation
Each addressable detector and monitor module can be assigned to one software alarm zone. Control
modules may be assigned to a maximum of three software zones. A general alarm zone (Z00) may be
listed for output (control) points, but it is not necessary to list Z00 for input points, as this is the default
zone. Z00 is not activated by supervisory points.
When an input device (detector, monitor module) alarms and is not disabled, it activates all software
zones assigned to it. An output device (control module or NAC) that is not disabled is turned on when
any of the software zones, to which it is mapped, become active.
Note:
For more information on CBE operation, refer to "Appendix C: Software Zones" on page 80”.
Detector Functions
Maintenance Alert
Each detector is monitored by the control panel for its maintenance status. If a detector is within 80% of
its alarm threshold for a 24-hour period, a “Maintenance Alert” message will be automatically
displayed, signaling that the detector needs servicing.
Automatic Test Operation
An automatic test of each detector is performed every 2 hours. The detector's sensing chamber and
electronics are functionally tested for normal, safe operation. A trouble message is displayed upon
failure of this test. You can also clear this trouble by pressing the
SYSTEM
RESET
key.
Type Code Supervision
The control panel monitors hardware device type codes at slow intervals. Mismatch of any type code,
compared to the system program, will cause a device trouble.
System Alarm Verification
You can also program the control panel to perform alarm verification to detectors. Refer to "Alarm
Verification (None or 73 Seconds)" on page 67 for a description of the Alarm Verification Timer.
Time Functions: Real-time Clock
The control panel includes a crystal-based clock that provides time of day, date and day of week. Time
is displayed as 12 hour time with month/day/year and is stored in RAM. If both AC and battery power
are lost, the time must be reset.
