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. If the panel appears to be operational, then a reset will clear the fault.
The only exception to this is the write enable switch. In access levels 1, 2A and 2B, if the switch is on, a system
fault will be indicated on the LEDs and display. The fault relay will be off (to indicate a fault condition). 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, power down completely and check
that 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.
ZONE SOUNDERS
Yellow
Flashing
Continuous
A fault condition is present on a Twinflex zone circuit.
A device or an action associated with the zone
sounder circuits has been disabled.
FIRE OUTPUTS
Yellow
Flashing
Continuous
A fault condition is present on the monitored fire
circuit.
A device or an action associated with the monitored
fire circuit has been disabled.
SOUNDER OUTPUTS
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.
DAY MODE
Yellow
Continuous
The system has gone into the less sensitive day
mode as programmed.
SERVICE
Yellow
Flashing
Continuous
The pre-programmed weekly test is due.
The pre-programmed service interval has expired
and a routine maintenance check is due.
DELAY
Yellow
Continuous
An action has been setup 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.
