4.11 Programmed Zone Operation
Each addressable detector and monitor module can be assigned to a maximum of five
software alarm zones. A general alarm zone Z00 may be listed for output (control) points,
but it is not necessary to list Z00 for input points, since this is the default zone for all alarm
input devices. Zone Z00 is not activated by supervisory points.
When an input device alarms and is not disabled, it activates all software zones assigned to
it. An output device that is not disabled is turned on when any of the software zones to
which it is programmed become active.
4.12 Disable/Enable Operation
Input points which are disabled do not cause an alarm or any zone activation. Disabled
output points are held in the off state. All disabled points are treated as if they were in
trouble, with the exception being the status label that will be displayed is DISABL.
4.13 Waterflow Circuits Operation
If an alarm exists from a monitor module point that has a waterflow type code and its
mapped NAC control module outputs are programmed for nonsilenceable operation, the
Alarm Silence key will not function.
4.14 Detector Functions
Maintenance Alert
Each addressable detector is monitored by the control panel for its maintenance status. If
a detector is near but below the allowed alarm limit, a ‘maintenance alert’ message will
automatically be displayed, signaling that the detector is in need of servicing.
Automatic Test Operation
An automatic test of an addressable detector is performed each minute, resulting in a
complete SLC loop test in approximately 2 hours and 40 minutes (if the loop has the
maximum number of devices installed). The detector’s sensing chamber and electronics
are functionally tested for normal, safe operation. A trouble message is displayed upon
failure of this test. A System Reset will clear this trouble.
Type Code Supervision
The control panel monitors addressable hardware device codes at slow intervals.
Mismatch of any type code, compared to the system program, will cause a device trouble.
System Alarm Verification
The control panel may be programmed to perform alarm verification to help eliminate the
nuisance of false alarms. Alarm verification applies to smoke detectors only.
Smoke Detector Data
Smoke detector data is monitored by the FACP, eliminating the need to test the sensitivity
of each detector at its location. A printout of each detector’s data can be retrieved from
the FACP using an optional printer. Detector sensing ability can decrease with age and
should be monitored as part of a system’s routine maintenance.
4.15 Time Functions: Real-Time Clock
The Unimode 9600 includes a crystal-based clock that provides time of day, date and day
of week. Time is displayed as 12 or 24 hour time with month/day/year and is stored in
RAM. Daylight savings time change-over is programmable and automatic. If both AC
and battery are lost, the time must be reset.
