Operating Instructions Disable/Enable Operation
118 MS-9600 PN 51335:E 7/9/03
4.11 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.
4.12 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.
4.13 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.
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 or Windows

HyperTerminal.
Detector sensing ability can decrease with age and should be monitored as part of a
system’s routine maintenance.
4.14 Time Functions: Real-Time Clock
The MS-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.
4.15 NAC Operation
There are up to four programmable NACs (Notification Appliance Circuits) resident on
the MS-9600 main circuit board. The 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, California coding and
two-stage operation.
