Smudge807 Posted June 30, 2010 Posted June 30, 2010 i have installed a GT595 in a school which has been fitted for 7-8 months and has 2 expanders , a month ago i kept getting random faults on all zones on zex 2 , after checking it all out the zex seem to be at fault , which i changed , it has now just started doing the same thing again ,all used zones go active together very randomly .... cable feed to Zex fine (25 m run), zex in psu but power fed from panel (13.45v ) neutrals are linked , pirs fed off psu .I have 4 zones on one 12 core cable, which risco point to as a problem ie one of the zones on the 12 core playing up , all zones metre fine , no inductance , shorts etc all doing exactly as its says on the tin , risco saying zex ok as never comes up with zex tamper fault and zones not in use do not show up ........ Any ideas would be most welcome as starting to pull my hair out ... )-:

antinode Posted June 30, 2010 Posted June 30, 2010 I presume the PSU has been checked out and is OK? IE aux output fuse holder, voltages, battery, switches over on mains fail properly? Not a major Risco user so can't think of any model related problems. What about linking all zones out on Zex 2 and putting on them on soak, with a temporary Zex (address as 3) for the detection, just to narrow it down a bit? Trade Member
arfur mo Posted June 30, 2010 Posted June 30, 2010 i'd be suggest the same, also look at the inline batt fuse, and stretch the spring, very common issue causing many of the uncommon faults i'd also ask is the data link near mains or florescent lighting circuits? how often is it faulting, is it at a fairly regular time of/or day? are th expanders in a location subject to casing condensation. i'd also wonder if there a problem in the 1st ZEX data output, so an idea might be to swap them over, ZEX1 being thus far fault free. if there is a dry joint your testing to fault find might actually clear it for a while, until it go's 'dry' again.

Smudge807 Posted July 1, 2010 Author Posted July 1, 2010 Thanks for the replys guys , psu was checked out and is working fine , and zones are all EOL ... Will report back my findings

OP - are the zones EOL? perhaps posting about further that little problem you had with wireless kit - and me posting about moving switch 4 would be nice still waiting for the bottle of scotch - i'm getting very thirsty Arfur and my birthday is EARLY next month If you think education is difficult, try being stupid!!!!

Will report back my findings i, as others would be very interested smudge807, bit hard to diagnose when looking through the letter box, but a base point is the kit is generally very very reliable. so i'd tend to look for environmental issues, rodent damage to cables, or near hot pipes and so, this after i've checked out for human error (aka plonker fowl up's like a misplaced cable staple shorting).
