Ive recently replaced a wired system in the daughters house with a Honeywell kit. I also replaced all the connection wiring and moved the main control unit into an upstairs airing cupboard.
Installers tend to try and keep as much as possible close to the centre of the house, run the wires for their convenience and as near to the main control unit as they can because of limited access and less disturbance. As I was doing some re wiring and floor boards were up I was able to modify the locations of sensors and panels. All neatly done.
Only issue was that Honeywell stopped doing domestic kits so replacements components could be an issue down the line.
Systems may or may not have tamper circuits wired up which is just a continuous loop of 2 wire colours. The engineering code is required to disable the tamper circuit. This will be different from the user code.
The rechargeable led acid back up batteries have a limited lifespan and in the event of a power cut the alarm will continue to sound as there is no juice to take over from the mains.
Zs idea of changing the user code to operational keys sounds good to me.
The other issue with house alarms is that insurers ask for annual servicing. The annual premium reduction is not a lot and you can bet if you did make a claim they'd be looking at your servicing regime.
It is definitely a line of defence for your property.
If you can ascertain the make of the system you might have a chance for a replacement part. There are only 6 wires of which 2 are tamper circuit and I believe the other circuits are common throughout the industry.
