I am making some changes to my loft flooring but need to re-route the cable for the alarm bell box, as it presently runs over the top of a joist (where the water tank used to be).
The cable is jointed, handily where I want to re-route the cable, using a punch down joint box (connections like the back of a BT phone socket).
Am I right in presuming that even if I put the alarm panel into Maintenance mode (or to be even safer, turn off the alarm panel altogether (and disconnect its battery)?) then disconnect the bell box cable at the joint box then the alarm will still go off due to the anti tamper circuit and the battery in the bell box??
I am reluctant to get my ladders out to get to the bell box due to the snow and ice we have at the moment. Is there any wires I can short out on the cable to the bell box (or some other method) so the sounder doesn't go off when I disconnect the wiring at the joint box in the loft? (This would be the same as disconnecting the bell box wiring from the alarm panel without disconnecting the battery in the bell box?)
The bell box has the following connections:
A - +12v, B - Bell, C - Tmp, D - 0v, S - Strb
The alarm panel has the corresponding connections:
D - +ve supply, B - -ve bell, T - SCB, A - 0v, - Strobe
Many thanks for any advice received.
