Disable/Enable Operation Operating Instructions
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.
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.
4.15 Time Functions: Real-Time Clock
The NFW2-100 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.
4.16 Synchronized NAC Operation
Synchronization is a panel feature that controls the activation of notification appliances in such a
way that all devices will turn on and off at exactly the same time. This is particularly critical when
activating strobes which must be synchronized to avoid random activation and a potential hazard or
confusion. The FACP can be programmed to operate with a variety of manufacturer’s devices.
NAC synchronization can only be supported properly by the Remote Power Supply Sync Terminal,
which follows NAC 1 programming.
