Veritas R8 PIR problem

[Spark123]

OK, the wires should read about 0v when the PIR is not tripped and 12v when the PIR is tripped,

no it doesnt - theres NO volts across the alarm terminals

Then how does it work then?

I think the next easiest thing to try is to disconnect the wires from the alarm terminals and see how many volts there are on the panel

er, it`ll be none same as above

Odd, just tried it with a new panel and it read the line voltage for the panel with the wires disconnected.

terminals, hopefully there will be 12v which means the panel isn't at fault (and the link still isn't in from pre commisioning!!).

you dont do many alarms do you sparks

Nope, but I do work with instrumentation and electronics.

So your saying - with your test meter on volts you get a reading ACROSS the alarm pair ? I`d be very worried if I was you

you`ll only get a reading with reference to the 12v or 0v terminal - think about it - if there was 12v ACROSS the alarm relay the ffng fuse would blow everytime the sensor closed wouldnt it

you never heard of a short between poles (well of course you havnt, why should you have) or multicore cable ?

my fault finding ability isnt in question, certainly not by some half wit like yourself who couldnt even understand the opening post now #### off like you keep promising[/quote]
