I'm back again with this!
I disconnected my panic button to remove the kitchen unit it was bolted on to. The original wiires went up inside of cupboard, hole drilled through and panic button fitted on other side. My plan was to remove it put it back together and leave it on floor until new units fitted, then site it back again.
The door magnetic sensor is also wired through this button, in that the cable from that runs to the panic button.
tamper went off as predicted, user code silenced it.
However, the cables had to come out to enable the button to come off, I then wired it back the way it was, or so I think.
There were 2 single wires (green and white) wired across the central reed switch (?) thing. I assume this to be the panic button wiring (pressing the button makes it go open circuit?)
2 black wires (one from each cable), twisted and tinned, wired to a terminal with the black metallic strip - I think this is tamper (?)
Then pairs of wires from each cable (red, blue and yellow) twisted and tinned to each of 3 terminals at the bottom.
I put it all back together yet on walktest it shows "front/rear doors" as being open but they are shut!
Currently I've got the button off, I've twisted the single green and white that went across the switch together to remove the "panic alarm" fault. So this pair along with all the other pairs are now wrapped in insulating tape with the alarm unset.
How longwinded for something probably so straightforward to you all!
What have i got wrong? The only thing is some of the solder disintegrated a bit so I twisted the wire pairs together, would this be the issue?
Otherwise its alarm company out time, don't mind getting them - just a pain to get them out to remove a switch on a unit, then back again to but it back after - likely 2 call outs....
