Disable/Enable

The zone disable feature may be used to disable any zone in the system. Zones in alarm cannot be disabled but
zones in trouble can be disabled.

To disable one or more zones, press and hold the Disable/Enable key. After two seconds, the FACP will enter
Disable/Enable Mode. Continue pressing the Disable/Enable key to remain in this mode. Fire protection is still
active while in this mode. Releasing the key will return the FACP to Normal Mode.

While pressing the Disable/Enable key, any zones that were previously disabled will be indicated by the zone
trouble LED being on steady. A 'cursor' (blinking LED), which blinks at a 1/10 second On and 9/10 second off
rate, will be positioned at the Zone 1 trouble LED. Note that if Zone 1 was previously disabled, the 'cursor' will
blink at a 9/10 second On and 1/10 second Off rate.

To disable or enable a zone, continue pressing the Disable/Enable key and use the Up or Down arrow keys to
position the 'cursor' at the alarm zone trouble LED. Press the Reset (Enter) key to toggle the zone from enabled
to disabled or disabled to enabled. Note that the 'cursor' flash rate changes from 1/10 second On and 9/10 second
Off when enabled, to 9/10 second On and 1/10 second Off when disabled. Using the arrow keys to move the 'cur-
sor' away from the selected zone will cause the disabled zone's trouble LED to remain on steady. Continue this
process for each zone to be enabled or disabled.

When all desired changes have been made, release the Disable/Enable key to return the FACP to Normal Mode.
Note that the zone trouble LEDs for all disabled zones will be blinking along with the system trouble LED and the
piezo will be sounding. Pressing the Acknowledge key will silence the piezo sounder and change the blinking
LEDs to steady on.

Reset/Lamp Test

The System Reset key resets the system and any smoke detectors. A Reset key is located on the FACP keypad
(illustrated in Figure 4-1), and may be remotely on any of the LED-10 annunciators, the LDM graphic annuncia-
tors, or the AFM series annunciators. If any of the System Reset keys are pressed, the control panel will:

✓ Clear the status LEDs
✓ Turn off the Notification Appliance Circuits
✓ Reset all zones by temporarily removing power
✓ Silence the onboard piezo sounder
✓ Restore all system relays to normal
✓ Temporarily remove power from the resettable power output TB2 Terminals 3 and 4

Any alarm, supervisory or trouble condition that exists after a system reset, will resound the system, reactivating
normal system activity. Any zones that were disabled before the reset will remain disabled after the reset.

Lamp Test - If the Reset/Lamp Test key is pressed and held for more than two seconds, the FACP will perform a
Lamp Test. All panel LEDs will be turned on and the piezo will sound until the Reset key is released.

AC Power LED

A green LED that remains on while the AC power supply is within correct limits. If this indicator fails to light
under normal conditions, service the system immediately.

A yellow LED that blinks to indicate that a system fault or abnormal condition exists and that the fire alarm sys-
tem may be inoperative. It turns on steady when a Signal Silence or Acknowledge key is pressed.
