zone alarm even when omitted

[Jonks]

Hi, I've read Breezer's replies about alarm faults. I'll do all the checks suggested on 2 October but just wanted to see if there is an obvious answer first. I've had the same zone alarm triggered recently, even when it was omitted when setting the alarm. Could it still be a faulty sensor if omitted (or wire damage/mice)? I imagined it wouldn't trigger in this case.
Thanks

if a cct goes into alarm when omited, it is not omited.

some panels you have to programme it as "omit permit"

when omited ccts do not go off, BUT the tamper can, is it alarm or tamper that is going off

 

[Jonks]

Wow that was a quick reply!! Thanks.
It was a zone alarm not tamper.
It's an Accenta 6 and I've had it in use for years with the occasional blip due to a flat battery or over-sensitive sensor.
I've just checked the omit prevent zones using the engineer code and there don't seem to be any. I was surprised it triggered with the zone omitted. Would this happen with a dodgy wire?
Thanks

doubtful.

since when a device is operated it goes open which is what the panel is looking for.

other thing is you may be omiting the wrong one. i.e
you omit zone 3 becuse its the kitchen, but in fact zone 3 is the lounge

check the battery again

I omitted the one that had caused the alarm - though I wasn't sure then which room it was. I suppose it's just possible that I didn't omit the one I thought I had though I don't think so. I'm worried about upsetting the neighbours to try again!! Can I omit all zones except that one and stay in the house to check?

check the battery again

I'll do that. Would a failing battery do all sorts of unexpected things?

 

[breezer]

if your battery is 5 years old change it, batteries tend to drag things down when old, but most panels will give a warning first.

as for can you omit everything else, it depends if you can omit it or not, and how your system sets, if it is final door, you will have to open and close it to set, if its timed then just sit tight.

you could also set your alarm with one cct omited and violate each cct in turn, one should not go off, since you have omited it, but dont do it now, you really will upset the neighbours

ohh yes

 

[breezer]

wont cause a cct omited to activate though, low batteries tend to drag everything down, starting with what ever is on the longest cable run

you`ve almost thought it all the way through, keep on going

 

[Jonks]

Logical female? I'll enjoy the compliment!

I'll do a violation test during the day at the weekend - and get back to you if it doesn't work!!

Thanks.

one day you will type something amusing, that day has yet to come

we`ll see what happens when they change the battery first

sounds good to me.
