Hi,

Anyone able to give me some advice?

During the early hours when there was a heavy frost one of my two bell boxes (Tate) of my intruder alarm (Melcom) started intermittently sounding for short bursts (few secs max) in no regular pattern. It went on for a few hours and now it has stopped - ?starting to warm up?.

I tried putting the alarm on engineer setting, however despite this it continued to sound.

I assume that it must be a local fault in the bell box which hasn't triggered the tamper loop. What is the likely problem in your experience?

Thanks

Chris

Some bell boxs dont have a cover over the circuit boards and over time the board and sab module get damp and short, get a decent bell box......... risco or texecom

tate ? sounds like Risco made to me possibly

you`ll need to fit a link (details are in the instruction sheet)

if not there just old and got water damaged and will need changing IMO

Points to a intermittent positive feed at the sounders PCB board, looks like the laddders are coming out!

sounds like lid tamper opening and closing

maybe due to cold warping lid or metal spring on tamper

activating sab

did panel show a tamper

get a tin of pcb laquer )spray) and coat the pcb's, bought from rs components or maplins.

as above, risco sounders had a fault a while back. if it drops below -6 the sounder will chirp.

had the very problem this morning

i had loads, was a real PITA that one.
