TROUBLESHOOTING
Applicable for Function 6-4 only
a) Auto-address-device does not program
If during the course of programming an auto-address-device, the new address is not programmed in the module, verify
that the connections to both the loop and the device are correctly made. Confirm supply polarity of the device. Always
follow the manufacturer's instructions. Check loop voltage at the auto-address-device terminals followed by a verification
of the device voltage, measure voltage across the supply wires (black & red). In normal operation it should always be
greater than 17 V DC.
Verify the condition of the whole system, in particular supplies (auxiliary and loop), earth leakage, loop length too long,
loop with a short or open circuit and panel communications. If all of these are OK, then do a system reset after which you
should verify, using function 7-1, if there are devices with duplicated addresses. If there are, clear those addresses and
reprogram auto-address-devices that previously had identical addresses.
In the eventuality that one auto-address-device does not program but there is no evidence of two devices having identical
addresses after a system reset has been performed, clear the last programmed address using function 6-4-3 and
reprogram auto-address-devices. If that does not solve the problem, replace the auto-address-devices module.
Remember that a duplicate address fault will only show with ASET mode disabled.
b) Auto-address-devices with duplicate addresses
In an installation with auto-address-device, should there be a fault of 2 devices or more with the same address (duplicate
address fault) two actions can be taken:
1) CLEAR LOOP. Clear the loop where some auto-address-devices have duplicate addresses. See function 6.4.2. This action
should only be applied when in a brand new installation, where all auto-address-devices should have been blank (no
address programmed).
2) Alternatively the duplicated address can be erased using function 6.4.3
Reset the panel and verify, using function 7.1, the offending address and henceforth the associated FAULT condition has
disappeared. Re-program cleared devices. Repeat the procedure until the fault disappears. If after the third time the
address clearing procedure has been repeated the fault persists, replace those auto-address-devices that have duplicate
addresses. It should be observed that this verification can only be performed when ASET mode is disabled, since the fault
condition where 2 devices have the same address is not shown when in this particular mode.
7 Monitor Device Counts & Test
7-1 Device Count, Type & Value
Use this function to check that all loop devices are present.
Use 1
▲
3
▼
to select the device address on that loop.
Use 2
►
to select the panel loop.
This function is also useful to confirm the address of the various different types of devices connected to the Analogue
Loop. Note that in Installation Mode all information is live, i.e. the count of devices will change as the panel learns and
device types will be updated if they change. In Active Mode only the device value is live.
7-2 Test Sounders
Use this function to test the audibility of the sounders in a more comfortable manner than pressing SOUNDERS
ACTIVATE/SILENCE. The Panel Conventional Sounders will sound for 1 second and then be silenced for 9 seconds.
7-3 Sounders on Test Activation
This function allows you to choose an audible confirmation that a device has detected a fire. The audible confirmation
consists of a 1 second period of sounder operation. The settings selected by this function are used by ‘7-4 Test Zones’ and
‘6-4-1 Activate ASET Mode (Automatic Address Settings)’.
ALL SOUNDERS ON DETECTOR TEST activates the Panel Conventional Sounders and Loop Sounders.
