15. GENERAL FAULT FINDING

On the Premier AD panel, Faults are divided into 2 types, "Faults" and "Device Faults". Device Faults
are any fault associated with a particular address on the loop. Faults is everything else, EG sounder
circuits, power supply etc. In the event of multiple faults, the Faults are grouped together first,
followed by the device faults. Next button will scroll to next fault.

15.1 COMMON FAULT.

This is a general indicator which lights whenever a fault is present. It doesn't refer to a
specific fault.

15.2 LOOP CONTENTS FAULT FINDING

If the loop contents are different to what was expected, then there two probable causes:-
1. Two or more devices may have the same address setting. This is referred to as a double
address fault. If this occurs all devices with the same address will answer at the same time.
The panel will not be able to understand the answer it receives. NOTE: If a panel detects a
double address, it will light the LEDs of the devices with the problem. (NOTE: only
detectors will light their LED. Call points, sounders & interface modules will not be
indicated).
2. There may be some reversed connections to devices (they are polarity sensitive). The
Fyreye detectors should be connected Loop + to L2, loop – to L1IN. Other devices will have
their polarity marked by their connections.
If the panel reports any double addresses present, investigate these first as they are the easiest to
find. The panel will turn on the LED of any incorrectly addressed detector.
1. Make a list of the double addresses reported (there may be more than one).
2. Go to view device screen in Configuration menu 1. Scroll through the devices, and make a
list of any that are missing (note: the panel skips over empty addresses when scrolling)
3. Go to the location of the missing device, and check if it has its LED on (Detector), or check
the dip switch setting.
4. If this does not cure all double addresses, go to the known location, and temporarily remove
the device. The panel will now report the type of device that was also configured to this
address. This will help narrow down the search for the device. (eg if extra device is call point,
check all the call points)
If there are still less devices than expected, check the missing addresses for correct wiring polarity. If
in doubt, contact your supplier.
If the wiring polarity is correct, check that there is no cable break on the loop. (If there is a break, the
panel will report the break after 60 seconds or so, and inside the panel, the LOOP POWERED LEDS
(green) will alternate on & off). Some devices take a few seconds to power up, so may show as
missing during the repeated Power Down / Power Up cycle that occurs during a line break.

15.3 ZONE FAULTS

There are several reasons for the zone fault LED to light.
1. There is a cable break, or short circuit to devices in that zone,
2. A device has been removed from that zone
3. A device has been changed for one of a different type
4. There is a double address in this zone (see previous section)
4. A device in that zone is communicating a fault condition to the panel with its analogue value. A
value less than 8 is usually a fault condition. (This could be a zone monitor reporting a fault in its
zone wiring, for example.)
The LCD will show Device Fault, the user label, and the address
Of the fault. Pressing enter will bring up the View Device screen
for the device showing fault. This will give more information about the
fault.
In this example, the device is Missing. IE the panel is not receiving
an answer from this address. This could either be a removed detector,
a changed address switch setting, or a damaged detector.
Check the device has not been removed
Check that there is power to the base
Check address hasn't been changed (compare to system set-up chart)
