8. Move the CONFIG SLU DIL switch on the
control board to the OFF position.
NOTE: The SLU configuration is stored in
EEPROM and is retained when the panel
has no power.
4.3 Panel Quiescent State
The panel will be in the quiescent state when the
POWER SUPPLY ON LED is on steady, either the
AUTOMATIC & MANUAL LED or the MANUAL
ONLY LED is on steady and no other indications are
present on the display board or the control board.
4.4 Auxiliary Fire Condition
If a fire condition is detected on the Auxiliary zone,
the following occurs:
1. The FIRE LEDs pulse
2. The AUX ZONE FIRE LED pulses
3. The SILENCE ALARMS LED pulses
4. The FIRE SIGNAL output operates and the red
FIRE SIGNAL LED operates
5. The AUX ZONE FIRE output operates
6. Sounder circuits 1 & 2 operate
In this state, the buzzer can be silenced, both
sounder circuits can be silenced (and re-sounded if
necessary) and the fire condition can be reset by
operation of the FIRE RESET button.
4.5 Single Extinguishing Zone Fire
Condition
4.5.1. MANUAL ONLY MODE
If a fire condition is detected on either zone 1 or
zone 2 while the panel is in the MANUAL ONLY
mode, the following occurs:
1. The FIRE LEDs pulse
2. The ZONE 1 FIRE or ZONE 2 FIRE LED
pulses
3. The SILENCE ALARMS LED pulses
4. The FIRE SIGNAL output operates and the
red FIRE SIGNAL LED operates
5. The ZONE 1 FIRE or ZONE 2 FIRE output
operates
6. Sounder circuits 1 & 2 operate
In this state, the buzzer can be silenced, both
sounder circuits can be silenced (and re-sounded
if necessary) and the fire condition can be reset by
operation of the FIRE RESET button.
4.5.2. AUTOMATIC & MANUAL MODE
If a fire condition is detected on either zone 1 or
zone 2 while the panel is in the AUTOMATIC &
MANUAL mode, the following occurs:
1. The FIRE LEDs pulse
2. The ZONE 1 FIRE or ZONE 2 FIRE LED
pulses
3. The SILENCE ALARMS LED pulses
4. The FIRE SIGNAL output operates and the
red FIRE SIGNAL LED operates
5. The ZONE 1 FIRE or ZONE 2 FIRE output
operates
6. Sounder circuits 1 & 2 operate
7. The SYSTEM ACTIVATED LED pulses (pre-
activated condition)
8. The 1
st
Stage Shutdown output operates
In this state, the buzzer can be silenced, both
sounder circuits can be silenced (and re-sounded
if necessary), the fire condition can be reset by
operation of the FIRE RESET button and the
extinguishing pre-activated condition can be reset
by operation of the EXTINGUISHING SYSTEM
RESET button.
4.6 Two Extinguishing Zones Fire
Condition
4.6.1. MANUAL ONLY MODE
If a fire condition is detected on both zone 1 and
zone 2 while the panel is in the MANUAL ONLY
mode, the following occurs:
1. The FIRE LEDs pulse
2. The ZONE 1 FIRE and ZONE 2 FIRE LEDs
pulse
3. The SILENCE ALARMS LED pulses
4. The FIRE SIGNAL output operates and the
red FIRE SIGNAL LED operates
5. The ZONE 1 FIRE & ZONE 2 FIRE outputs
operate
6. Sounder circuits 1 & 2 operate
In this state, the buzzer can be silenced, both
sounder circuits can be silenced (and re-sounded
if necessary) and the fire condition can be reset by
operation of the FIRE RESET button.
4.6.2. AUTOMATIC & MANUAL MODE
If a fire condition is detected on both zone 1 and
zone 2 while the panel is in the AUTOMATIC &
MANUAL mode, the following occurs:
1. The FIRE LEDs pulse
2. The ZONE 1 FIRE and ZONE 2 FIRE LEDs
pulse
3. The SILENCE ALARMS LED pulses
4. The FIRE SIGNAL output operates and the
red FIRE SIGNAL LED operates
5. The ZONE 1 FIRE & ZONE 2 FIRE outputs
operate
6. Sounder circuits 1 & 2 operate
7. The SYSTEM ACTIVATED LED illuminates
steady (activated condition)
8. The 1
st
Stage Shutdown & 2
nd
Stage
Shutdown outputs operate
9. The pre-discharge delay timer starts
10. The Extinguishing System Reset Inhibit timer
starts and the INHIBITED LED illuminates.
11. The Extinguishing Sounder circuit pulses 1
second on, 1 second off.
In this state, the buzzer can be silenced, only
sounder circuits 1 & 2 can be silenced (and re-
sounded if necessary), the fire condition can be
reset by operation of the FIRE RESET button.
