54 Amended: Jan 2014Problems“Dual address”The dual address should be displayed on the screen the panel sees this fault if two or moreaddresses are responding at the same time.Other effects of the dual address could be the displaying of devices that have not been installed, theresults of which could be a Beam detector, an SCU (sounder controller), a 4/20 mA interface or theworst case a Repeater Panel which causes a continual resetting of the main panel.This is because the analogue levels of the 2 devices that have dualled are added together therebyfooling l the panel into believing those devices exist on the system.The most likely causes would be:-Device wired incorrectly. See wiring diagram for the deviceBase continuity switch not opening. The switch on the base can occasionally be pushed above themetal tab preventing the switch from opening. See diagrams below.Correct IncorrectFIG 50If this is the case the switch may need to be clicked under the tab, if this fails the base may needreplacing.Alternatively on later versions of the detector base the spring has been rotated to provide a morelogical operation. Certain instances of this base (up to May 2013) can cause a dual address becausethe tooling of the spring was found to be too acute, which allows the spring to break and then remakeat the extent of its travel.This modification was not carried out on the base sounder, sounder /beacon (see also fig 53)FIG 51
