Ok,  I had a brief look when I last introduced an extra zone PIR to the panel and I noticed that it goes across zone 1 .  Would the activation terminals be on the Trig terminals to left side of the panel under the aux supplies?? 

Thanks for your help...

No, it would go to a spare zone and need programming appropriately. 

Hi,  thanks for your help.  I hav'nt looked closely at the wiring from the reader but I would guess it will have a 12V supply it goes across Zone 1 and will also have a switch line going back to the panel to activate it.  If it's working as a simple switch the only programming would be learning and accepting the key fobs .  I would like to understand how it activates the panel and also does it use the zone as a kind of tamper ??

Cheers

it activates the panel as the circuit its connected too will be programmed as keyswitch

It requires a simple volt free contact, the reader is powered but the output to the panel is volt free. 

So zone 1 is programmed as a key switch and activates closed circuit or open circuit?

If that's where the existing reader is connected to then yes. 

Thanks

I recently added another pir to the panel on zone 8.  Although the test function acknowledges the pir works it isn't activating the alarm.  It wasn't previously used and originally had a resistor across it which I have removed.  I have changed over zones 7,8 and to test the pir and wired into zone 7 it works fine and activates the alarm.

but zone 8 is still not activating the alarm.  Any idea what the cause may be.

I'd suggest zone 8 is programmed as spare.

 

How did you test it?

So I would need to re-program the panel but I don't have an engineers's code for it.  The panel was fitted by ADT.  It was here when we moved in.  Any way round this.
