Time Functions: Real-Time Clock Operating Instructions
Automatic Test Operation
An automatic test of an addressable detector is performed each minute, resulting in a complete SLC
loop test in approximately 1 hour (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 MS-9050UD 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 sav-
ings 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.
Important: When a Notification Appliance Circuit with a mix of audible and visual devices is
programmed for silenceable and the synchronization feature is selected, only the audible devices
will be turned off if the Silence key is pressed. The visual devices (strobes, etc.) will continue to
operate.
4.17 Coded Operation
The NAC circuits resident on the control panel main circuit board can be programmed for coded
operation. The available pulse rates which can be programmed for coded operation are as follows:
• Continuous: Steady output with no pulsing
• March Time: Pulses at 120 ppm (pulses per minute)
• Temporal Code: Pulses at ½ second On, ½ second Off, ½ second On, ½ second Off,
½ second On, 1½ second Off
• California Code: 10 seconds On, 5 seconds Off
• Two-Stage Pulses at 20 ppm (pulses per minute) for 3 or 5 minutes
and then changes to Temporal
