LEDs to steady on. The second press of the switch stops the scroll-
ing and holds the event on the display for one minute. Subsequent
pressing of the switch 'steps' through each active event.
2.2.3 Silence
When the Silence switch is pressed and released, the LCD-40 sends
a signal silence command to the control panel. The Silence switch
performs the same functions as the Acknowledge switch. In addi-
tion, if an alarm exists, it turns off all silenceable NACs and causes
the FACP Alarm Silence LED to turn on while the LCD-40 will dis-
play a 'silenced' message. It also sends an 'Alarm Silenced' message
to the printer and the history file within the MS-9200. A subsequent
new alarm will resound the appropriate NACs (Notification Appli-
ance Circuits) and local sounders.
2.2.4 Drill: Hold 2 Sec.
When the Drill switch is pressed and held for at least two seconds
(time required to prevent accidental activations), the LCD-40 will
transmit a drill command to the control panel. This command causes
the FACP to turn on both main panel NAC outputs and all silence-
able circuits (all C300/C304 modules/NACs that are programmed
silenceable). In the event that the system was previously silenced,
the drill command will also turn off the Alarm Silence LED. The
'Manual Evacuate' message is shown on the LCD-40 display. The
same message is sent to the FACP display, printer and history files.
The Silence switch operates on silenceable NAC outputs only.
2.2.5 Reset
When the System Reset switch is pressed and released, the LCD-40
sends a Reset command to the control panel. This will turn off all
C300/C304 modules and Notification Appliance Circuits, tempo-
rarily turns off resettable power to 4-wire detectors, causes a 'System
All Normal' message to be displayed on the LCD-40 and sends a
'System Reset' message to the FACP display, printer and MS-9200
history files. It also turns on all system LEDs, piezo sounders and
LCD display segments as long as the Reset switch is held (lamp
test). Any alarm or trouble that exists after a Reset will resound the
system.
