I've been asked to fit an alarm for a customer.
They currently have a wired one that is 20 years old, so needs replacing
as it is falling apart, especially the door sensors.

Fitting a wireless one would be far easier for me, but are they reliable
enough?

If the existing wiring is sound and the sensors, panel and sounder are
in the right places its a simple swap out job. Lots of similar models
on the market now so ask at your local electrical wholesale suppliers
which are readily available rather than getting a hard to source model.

No, complete rewire, so best done while doing that.
The old one is unreliable, with numerous wires going all over that
cannot be traced, so I dont really want to work on it to try and fix it
when new alarms are £100ish.
