Controls and Indications Continued
TABLE 1
A
SUPPLY HEALTHY
Indicates permanently when panel is correctly powered.
B
TEST MODE
Pulses when the control panel is in engineer’s test mode. The individual
circuit fault lamp will be on (steady) whilst the circuit is in test mode. It is not
possible to test a disabled zone. See page 33 “Test Mode” for more details.
C
DISABLED
Indicates when a zone or sounder circuit has been disabled using the disable
button on the keypad. The LED pulses when disablement mode is selected
and remains on steady if any disablement is present on any of the circuits.
The individual circuit fault lamp will be on (steady) whilst the circuit is
disabled. See page 34 “Disable Zones or Sounders” for more details.
D
ARW
Automatic Reset Warning, Indicates if the processor has been rebooted. Will
indicate when panel is first powered up. See fault finding section for more
details.
E
“ENABLE CONTROLS” KEY-
SWITCH
Key-switch to activate the buttons on the keypad. They do not function unless
this switch is in the on position
F
POWER SUPPLY FAULT
Indicates a fault with the power supply. A fast pulse = battery fault. A slow
pulse = voltage faults. An intermittent blip = mains fault. Constant LED = volt-
age out of range. See fault finding section for more details.
G
EARTH FAULT
Indicates an earth fault on the system. See fault finding section for more
details.
H
REMOTE OUTPUTS ACTIVATED
Indicates if the remote fire and fault relays have been activated
I
REMOTE OUTPUTS FAULTY /
DISABLED
Indicates if the remote relay outputs are faulty or have been isolated using
the isolate remote button on the keypad. This LED also indicates short or
open circuit faults on monitored input. Slow pulse = open circuit. Fast pulse =
short circuit.
J
DETECTOR REMOVED ON ZONE
Indicates that a detector has been removed on this zone. See fault finding
section for more details.
K
SOUNDER CIRCUIT FAULT
Indicates that there is a fault on the individual sounder circuit or that the
sounders have been disabled or are in test mode. A fast pulse = short circuit.
A slow pulse = open circuit. All zonal sounder circuit fault LEDs are on
(steady) for disabled or test mode. Note:- disablement or test mode will have
priority. See fault finding section for more details.
L
COMMON FAULT
Dual LEDs Indicate when any fault occurs. Also if Test Mode is activated or if
zones or sounders have been disabled. Pulsing when fault buzzer sounding,
intermittent pulsing when fault buzzer muted (by pressing the ENTER button)
Note:- when a mains failure fault is present the LEDs blip intermittently to
conserve the batteries. See fault finding section for more details.
M
COMMON FIRE
Dual LEDs Indicate when any zone is in fire. Pulsing when fire or evacuate is
active, will steady when alarms silenced.
N
ZONE FAULT / DISABLED / IN
TEST
Indicates that there is a fault on this zone, or that the zone is in test mode, or
has been disabled. LED on (steady) in “test mode” or “disabled“. A slow
pulse = open circuit. A fast pulse = short circuit. Note:- disablement or test
mode will have priority. See fault finding section for more details.
O
FIRE ON ZONE
Indicates that there is a fire condition on this zone. Pulses when in fire, will
steady when alarms silenced. New zones in fire will pulse until silence
alarms is pressed again while the existing silenced zones will remain steady.
