Has anyone any opinions on, or experience of, the pros and cons of a new alarm system being wired or wireless? 1950's House is being re-wired and re-decorated.
Electrician No.1 swears new alarm should be wired, taking opportunity to chase walls etc. for a more reliable system without repeated nuisance call backs and replacement of batteries, and cheaper to install than wireless as extra labour of wiring is offset by substantially cheaper sensors.
Electrician No.2 swears that it must be wireless, for more reliable system... easier fault finding, (no mention of callbacks), batteries replaced regularly 2-yearly, and cheaper to install than wired because higher cost of transmitting-sensors is offset by saving of labour!
