Time Functions: Real-Time Clock

4.10 Time Functions: Real-Time Clock
The MS-9200 includes a crystal-based clock that provides time of day, date and day of week. Time is displayed as 12
hour time with month/day/year and is stored in RAM. If both AC and battery power are lost, the time must be reset.

4.11 Coded Operation - NAC 1 and NAC 2

Shown below are the pulse rate outputs via NAC 1 or NAC 2 when coded operation is selected. Note that software
releases prior to P/N 73750 allow coding of only NAC 1. Releases 73750 or greater allow coded functions on both
NAC 1 and NAC 2.
CONTINUOUS:
MARCH TIME:
TEMPORAL CODE: Pulses at ½ second On, ½ second Off, ½ second On, ½ second Off, ½ second
CALIFORNIA CODE: 10 seconds On, 5 seconds Off

4.12 Presignal

Presignal is used to delay output activation (control modules and NACs) while allowing for visual verification by a
person. Once a detector or monitor module triggers an alarm, the onboard piezo sounds immediately, but the Notifi-
cation Appliance Circuits are not activated for 15 seconds. During this time, if the Acknowledge key is pressed, the
piezo is silenced and the notification appliances will not activate for up to three minutes. After three minutes, the
NACs will activate if the source of the alarm is not cleared. This does not affect monitor modules programmed as
waterflow or supervisory. Presignal operation requires the approval of the local A uthority Having Jurisdiction.

4.13 Special System Timers

4.13.1 Silence Inhibit Timer (None or 60 Seconds)
This option, if selected, prevents the Alarm Silence key from functioning for 60 seconds after an alarm. A new alarm
during the initial 60 seconds will cause the timer to restart with a new 60 seconds. Silence Inhibit operation requires
the approval of the local A uthority Having Jurisdiction.
4.13.2 Auto-silence Timer (None or 10 Minutes)
If Auto-silence is selected, the notification appliances will be silenced automatically after ten minutes of activation.
Pressing the Drill key will restart the timer with a new 10 minutes. A uto-silence operation requires the approval of
the local A uthority Having Jurisdiction.
4.13.3 Trouble Reminder
If selected, this feature causes a reminding 'beep' every 15 seconds during an alarm (after the Silence key is pressed)
and every two minutes during a trouble condition (after the Acknowledge or Silence key is pressed). The 'beeps' from
the onboard piezo sounder will occur until the alarm or fault is cleared.
No Pulse
Pulses at 120 ppm (pulses per minute)
On, 1½ seconds Off
