4.1
Control Switches (Keys)
4.1.1 Acknowledge/Step
The Acknowledge/Step key silences the piezo sounder and changes all flashing LEDs to steady. Only one press is
necessary regardless of the number of new alarms, troubles or supervisory signals. When the piezo is silenced, an
'Acknowledge' message is sent to the printer and the history file. Multiple active events are scrolled on the display at
a three second rate. Acknowledge also automatically sends a 'Silence Piezo' command to the LCD-40, AFM and
LDM Series annunciators.
When more than one event exists, the first press of the Acknowledge/Step key silences the piezo and changes all
flashing LEDs to steady. The second press of the key stops the scrolling and holds the event on the display for one
minute. Subsequent pressing of the key 'steps' through each active event.
4.1.2 Alarm Silence
The Alarm Silence key performs the same functions as Acknowledge/Step. In addition, if an alarm exists, it turns off
all silenceable circuits and causes the Alarm Silence LED to turn on. It also sends an 'Alarm Silenced' message to the
printer, the history file and the LCD-40. A subsequent new alarm will resound the system.
4.1.3 Drill Hold 2 Sec.
When the Drill key is held for two seconds (time required to prevent accidental activations), the MS-9200 turns on
both main panel NAC outputs and all silenceable circuits (all control modules/NACs that are programmed silence-
able) and turns off the Alarm Silence LED. The 'Manual Evacuate' message is shown on the LCD display. The same
message is sent to the printer and history file. The Silence key operates on silenceable NAC outputs only.
4.1.4 System Reset
Pressing the System Reset key turns off all control modules and NACs, temporarily turns off resettable power to 4-
wire detectors, causes an 'All Systems Normal' message to be displayed on the LCD and stores 'System Reset' in the
