Hi guys,
My name is Phil,i am an electrician and now and again i work on fire alarms.
I have tested and changed Batteries,and detectors that type of thing.
I work for several landlords and most of the systems are twinflex and multipoint.
I have a fault on one system at the moment that i could do with a little help.
I was getting nuisance alarms from zone 3,there is three detectors on zone 3,1 in each of the
two bedrooms and 1 on the landing.The detector in the first bedroom had its led on solid,
I have had this twice before at other houses and had to change the detector both times.
So i changed the detector.I powered down,and fitted the new detector,powered up after about 10
seconds the alarm goes off.I thought the new one may be faulty so i changed it for another one
but still same.Basically any detector put into that bedroom sets the alarm off.Its fine with no detector plugged into the base.I have also changed the base.I have tried the new detector in another location
and it works fine.There seems to be a problem just with any detector plugged into that base.
I spoke to Rafiki but they were no help really other than saying it could be noise on the cables.
The system is 8 years old and been ok till now.
Can anybody help?
Hi There,
Thank you for your reply,yes i am sure the detector is compatable,it has all the exact numbers on it.
I am aware that the detectors and detector sounders are identicle in appearance.I have also tried two other
detectors from other locations in the building.The panel is a CB200 4 zone.
Hi,
Thank you for your reply,the detectors are fike Rafiki multipoint detector with sounder,model no 202/0001.
The room where the detector is mounted is empty at the moment,i have tried fitting the detector with a air tight cover
over it,which made no difference.The whole system works fine with nothing plugged in that bedroom.As soon as any
one off 3 detectors that i have tried is plugged in,within a few seconds the led on the detector lights up and the alarm goes off.
How is this individual detector location wired? Trunk line with an out-back run? Straight shot between devices with minimal turns and bends? (I notice that some of the Fike systems are picky about out-back runs. They say NOT to use a two pair cable. Use two one pair cables.)
According to the manual this system uses an end of line capacitor. I had minimal contact with other systems but did hear about other brands using EOLC, and a EOL capacitor failing can cause weird problems. Have you substituted the EOLC?
Its possible about the leak as the bedroom has a bathroom above it.Could be worth a try changing zones,not been back over xmas.Each zone has a break glass as the last item in the zone,the break glass has dip switches in that are set for eol.The cable looks like standard cable with foil inside,not twisted pair.
So shielded pair cable. Check that the shield is connected all the way through the circuit from panel to the last device. Also be sure the shield is not grounded anyplace but at the panel. Sometimes the shield works better if connected to power supply negative rather than earth ground.
