This is a yellow LED that flashes when a supervisory
alarm or zone trouble condition occurs on the
corresponding zone. The LED flashes at a 1/2
second on/1/2 second off rate along with the red
zone LED above it for a zone supervisory alarm.
The LED flashes at a 1 second on/1 second off rate for a zone trouble condition.
The piezo sounder will pulse at a rate corresponding to the flashing LED. The LED
illuminates steadily when the Acknowledge or Silence key is pressed and the piezo
silences. The LED turns off when all trouble conditions on the corresponding zone
are cleared. The LED turns off when all supervisory alarms on the corresponding
zone are cleared and the Reset key is pressed.
Note: When the MS-5210UD is programmed for Canadian supervisory annuncia-
tion, only the yellow LED flashes for a supervisory alarm condition. The red LED
above it remains off. Refer to the MS-5210UD Manual P/N 50193.

The key-switch is used to enable and
disable the operation of the membrane
(control) switches if switch 1 on DIP switch
SW2 has been placed to the ON position.
To enable the Acknowledge, Silence, Drill
and Reset function keys, insert a standard
Fire•Lite key into the key-switch located at
the top right corner of the LED-10. Make
certain the key is inserted completely
before attempting to turn it. Turn the key
clockwise until it stops. Leave the key inserted while pressing the function key(s).
When finished with the function keys, turn key-switch counterclockwise to disable
function keys.
Note: The key-switch should normally be in the disabled position (fully counter-
clockwise), with the key removed and access to the key restricted to authorized
personnel only. Do not leave the key unattended in the LED-10.
Acknowledge Acknowledge Acknowledge
Acknowledge Acknowledge
When the Acknowledge key is pressed and
released, the LED-10 sends an Acknowledge
command to the control panel. Pressing the
Acknowledge key silences the local piezo
sounder, the sounders located in all other system
annunciators 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.
