4.1 Panel Control Buttons

4.1.1 Acknowledge
The first press of the Acknowledge key silences the piezo sounder, changes flashing LEDs to steady, and also changes the status field on
the LCD display from capital letters to small letters. When the piezo is silenced, an acknowledge message is sent to the printer and the
history file. Acknowledge also sends a silence piezo command to the optional annunciators connected to the FACP.
When more than one event exists, the first press of the Acknowledge key functions as described in the preceding paragraph. Subsequent
pressing of the key steps through each off-normal active event, with alarm events having a higher priority than trouble and supervisory
events.
4.1.2 Alarm Silence
The Alarm Silence key performs the same functions as Acknowledge/Step. In addition, if an alarm exists, it turns off all silenceable
NACs (Notification Appliance Circuits) and causes the Alarm Silenced LED to turn on. It also sends an 'alarm silenced' message to the
printer, history file and optional annunciators. A subsequent new alarm will resound the system NACs. Note that the Alarm Silenced
LED is turned off by pressing the Reset key, the Drill key or subsequent activation of the NACs.
4.1.3 Drill/Hold 2 Sec
When the Drill key is held for a minimum of two seconds (time required to prevent accidental activations), the FACP turns on both main
panel NAC outputs and all silenceable circuits such as control modules that are programmed as silenceable, and turns off the Alarm
Silenced LED if it was previously on. The EVAC IN SYSTEM message is shown on the LCD display. The same message is sent to the
printer and history file. The Alarm Silence key can be used to turn off all silenceable NAC outputs following activation by the Drill key.
4.1.4 Reset
Pressing and releasing the Reset key turns off all control modules and NACs, temporarily turns off resettable power to 4-wire detectors,
causes a RESET IN SYSTEM message to be displayed on the LCD and sends the same message to the printer and history file. It also per-
forms a lamp test by turning on all LEDs (except the Ground LED), piezo sounder and LCD display segments after the Reset key is
released. Any alarm or trouble that exists after a reset will resound the system.
4.1.5 Function Keys F1-F4
The four function keys are user programmable. These keys can be programmed to allow rapid disable/enable of various fire panel inputs
and outputs during scheduled maintenance. Refer to "Function Keys" on page 72 for instructions on programming. Slide-in labels are
provided on page 159.

4.2 LED Indicators

The 11 LED indicators, which are located on the front panel, operate as follows:
Fire Alarm
This red LED flashes when one or more alarms occur. It illuminates steady when the Acknowledge/Step or Alarm Silence key is pressed.
The Fire Alarm LED turns off when the Reset key is pressed. The LED will remain off if all alarms have been cleared.
CO Alarm
This red LED flashes when one or more alarms occur. It illuminates steady when the Acknowledge/Step or Alarm Silence key is pressed.
The CO Alarm LED turns off when the Reset key is pressed. The LED will remain off if all alarms have been cleared.
AC Power
This is a green LED which illuminates if AC power is applied to the FACP. A loss of AC power will turn off this LED
Supervisory
This is a yellow LED that flashes when one or more supervisory conditions occur, such as a sprinkler valve tamper condition. It illumi-
nates steady when the Acknowledge/Step or Alarm Silence key is pressed. It turns off when the Reset key is pressed and remains off if all
supervisory alarms have been cleared.
Trouble
This is a yellow LED that flashes when one or more trouble conditions occur. It stays on steady when the Acknowledge/Step or Alarm
Silence key is pressed. The LED turns off when all trouble conditions are cleared. This LED will also illuminate if the microprocessor
watchdog circuit is activated.
Ground
This is a yellow LED that flashes to indicate a ground fault condition (zero impedance from the FACP to ground).
Battery
This is a yellow LED that flashes to indicate a low battery voltage condition.
