NAC Operation

4.10 NAC Operation
There are four programmable NACs (Notification Appliance Circuits) resident on the
MS-9200UDLS main circuit board. All NACs may be programmed as silenceable or
nonsilenceable and may also be programmed for steady or coded operation. Coded operation
provides a choice between March Time, Temporal or California coding.

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. Only alarms, hazards/tornado alerts can turn on any of the four main
NACs.

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. Also, any output zone activated by a waterflow device will not be silenceable if the
Waterflow Silenceable option is set to NO in system programming.

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 5 hours (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 FACP 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.
