FIRE OUTPUT
Yellow
Flashing
Continuous
A fault condition is present on a monitored Relay
circuit.
A device or an action associated with the monitored
relay circuit has been disabled.
DAY
Yellow
Continuous
The system has gone into the less sensitive day
mode as programmed.
ROUTINE SERVICE
Yellow
Continuous
The pre programmed service interval has expired
and a weekly test or routine maintenance check is
due.
DELAY
Yellow
Continuous
An action has been started which utilises a
programmed delay.
ALARMS
Yellow
Flashing
Continuous
The alarm sounders have been activated
The alarm sounders have been silenced whilst
operating, and the system is awaiting a reset.
BUZZER SILENCED
Yellow
Continuous
The control panel buzzer has been silenced whilst
operating and will stay silenced until another fault or
relevant action occurs.
During a system fault, dependent upon what caused the fault, all relays will be off, all zones will be powered down, the
zone, power fault and disabled LEDs will be on continuously. If any output is set to sounder then the Sounder LED will
also be on continuously.
To recover from this the panel should be powered down for approximately 2 minutes and then re-powered. This should
be done by a competent person and entered in the log at the end of this manual. If the panel appears to be operational,
then a reset will clear the fault and should be entered into the log at the end of this manual.
The only exception to this is the write enable switch. In access levels 1 and 2, if the switch is on, a system fault will be
indicated on the LEDs and display, the fault relay will be off but it has no effect on the operation of the panel and serves
as a reminder to the Engineer to switch off write enable before leaving the panel.
If the display is blank and no LEDs are showing, then either the unit is not powered or the mains has failed and the
batteries are lower than 21V. To recover from the low battery shut-off, down power completely and check the batteries
are no lower than 21V and then power up the system.
If the batteries are lower than 21V, then they should be replaced or monitored during initial charging to ensure they
recharge correctly. This could take several hours.
If the batteries are below 18V they should be replaced as they will have lost much of their capacity and are unlikely to
recover. This could leave the system with no power under mains fail conditions.
SOUNDER
Yellow
Flashing
Continuous
A fault condition is present on a monitored sounder
circuit.
A device or an action associated with the monitored
sounder circuits has been disabled.
