MS-9200UDLS Series Manual — P/N 52750:H 4/14/2014 141
Time Functions: Real-Time Clock Operating Instructions
4.16 Time Functions: Real-Time Clock
The MS-9200UDLS 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.
4.17 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.
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.
4.18 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 1/2 second On, 1/2 second Off, 1/2 second On,
1/2 second Off, 1/2 second On, 1-1/2 second Off
• California Code: 10 seconds On, 5 seconds Off
• Two-Stage Pulses at 20 ppm (pulses per minute) for 3 or 5 minutes (depending on
programming) and then changes to Temporal
4.19 Presignal
Presignal option programs an initiating device to delay the activation of NACs and/or control
modules while allowing visual verification by a person. Once a detector or monitor module
triggers an alarm, the onboard piezo sounds immediately, but the NACs are not activated for a user
programmed time duration of up to three minutes. Note that the alarm relay and communicator will
respond to the initial alarm immediately. In addition, Zone 98 will activate. This zone can be
programmed to a control module which may be used to activate a sounder or indicator which the
installer designates as a Presignal indication. Do not assign Zone 98 to a Notification Appliance
Circuit when using this zone to indicate a Pre-signal condition.
After the programmed delay, the NACs will activate if the source of the alarm is not cleared. Note
that if a second alarm occurs during the programmed time delay, the alarm will be processed
immediately, causing activation of the appropriate output zones. The events which occur upon
Presignal activation are as follows:
 onboard piezo sounds immediately
 control panel LCD display will indicate a presignal event and the active point
 control points programmed to Zone 98 will activate
 annunciators (if enabled) will sound the local piezo, and pulse the alarm LED and zone LED
 outputs (NACs and control modules) of associated zones will be inhibited from activating
for a user programmed time delay of up to three minutes
