Problems
Dual address
The dual address should be displayed on the screen the panel sees this fault if two or more
addresses are responding at the same time.
Other effects of the dual address could be the displaying of devices that have not been installed, the
results of which could be a Beam detector, an SCU (sounder controller), a 4/20 mA interface or the
worst case a Repeater Panel which causes a continual resetting of the main panel.
This is because the device ID’s of the 2 devices are added together thereby fooling the panel into
believing those device types exist on the system.
The most likely causes would be: -
Device wired incorrectly. See wiring diagram for the device
Base continuity switch not opening. The switch on the base can occasionally be pushed above the
metal tab preventing the switch from opening. See diagrams below.
Correct Incorrect
Fig 61
If this is the case the switch may need to be clicked under the tab, if this fails the base may need
replacing.
Alternatively, on later versions of the detector base the spring has been rotated to provide a more
logical operation. Certain instances of this base (up to May 2013) can cause a dual address because
the tooling of the spring was found to be too acute, which allows the spring to break and then remake
at the extent of its travel.
This modification was not carried out on the base sounder, sounder /beacon.
