Fire-Lite LED-10 series Manual page 12

Acknowledge
When the Acknowledge switch is pressed and
released, the LED-10 sends an Acknowledge
command to the control panel. Pressing the Ac-
knowledge switch silences the local piezo sounder,
the sounders located in all other system annuncia-
tors and the sounder located on the Fire Alarm Control Panel's main circuit board.
It will also change all flashing system LEDs to steady on. Only one press is
necessary regardless of the number of new alarms, troubles or supervisory signals.
An acknowledge message is also sent to the printer and the history files in the
MS-5210UD.
Silence
When the Silence switch is pressed and released,
the LED-10 sends a Signal Silence command to the
control panel. The Silence switch performs the
same functions as the Acknowledge switch. In
addition, if an alarm exists, it turns off all silenceable
NAC outputs only and causes the FACP ALARM SILENCE LED and the LED-10
SIGNAL SILENCE LED to turn on. It also sends an ALARM SILENCED message to
the printer and the history file within the MS-5210UD. A subsequent new alarm will
resound the appropriate Notification Appliance Circuits (NACs) and local sounders.
Drill: Hold 2 Sec.
When the Drill switch is pressed and held for at least
two seconds (time required to prevent accidental
activations), the LED-10 will transmit a drill com-
mand to the control panel. This command causes
the FACP to turn on all main panel NAC outputs. In
the event that the system was previously silenced, the drill command will also turn
off the ALARM SILENCE LED. (The Silence switch operates on silenceable NAC
outputs only).
Reset
When the System Reset switch is pressed and
released, the LED-10 sends a Reset command to the
control panel. This will turn off all Notification Appli-
ance Circuits, temporarily turns off resettable power to
4-wire detectors, and sends a "SYSTEM RESET'
message to the FACP display, printer and MS-5210UD history files. It also turns on
all system LEDs, piezo sounders and FACP LED 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.
