Silence
When the Silence key is pressed and released, the
LED-10N sends a Signal Silence command to the
control panel. The Silence key performs the same
functions as the Acknowledge key. In addition, if an
alarm exists, it turns off all
silenceable NAC outputs
only and causes the FACP ALARM SILENCE LED
and the LED-10N SIGNAL SILENCE LED to turn on. It also sends an ALARM
SILENCED message to the printer and the history file within the SFP-1024. A
subsequent new alarm will resound the appropriate Notification Appliance Circuits
(NACs) and local sounders.
Drill: Hold 2 Sec.
When the Drill key is pressed and held for at least
two seconds (time required to prevent accidental
activations), the LED-10N will transmit a drill
command 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 key operates on
silenceable NAC outputs only).
Reset
When the System Reset key is pressed and released,
the LED-10N sends a Reset command to the control
panel. This will turn off all Notification Appliance
Circuits, temporarily turns off resettable power to 4-
wire detectors, and sends a "SYSTEM RESET'
message to the FACP display, printer and SFP-1024 history files. It also turns on
all system LEDs, piezo sounders and FACP LED display segments as long as the
Reset key is held (lamp test). Any alarm or trouble that exists after a Reset will
resound the system.
