Looking for advice on disabling our current alarm and replacing then replacing it (north London).
We've moved into a house with an old Castle Euro Meridian G2-16 (grade 3 with MSX card fitted) installed by Banhams. It had a separate phone line for remote access, but that got disconnected when the previous owners moved out, which caused an error code on the alarm (and means we can't use the alarm at all now). Banhams won't give us a reset code, and say it needs an engineer visit to reset it (for £200+).
A few times now the internal alarm/sounder (but not the exterior alarm) went off for 15 minutes at random, the keypad is not accepting the fobs or user code we had. I replaced the battery inside and that seemed to fix it the problem for the time being but who knows.
So first off we just want to disable the thing we have completely so the alarm doesn't go off. If I could do that myself that would be great, but happy to pay someone. Any advice on this?
Secondly I want to replace the unit with something more up to date, but I want to have full access to reset the thing myself. I guess this means I want the installer code. Banhams said they won't do that (which I get), but I don't want to be on the hook for £200 a pop for a reset or a £25/month contract. I'd love to have something that works with my home automation setup (I have a pretty broad home automation setup so could probably hook into most things...). In terms of security, I'm not after Fort Nox cyber security stuff, I'm just looking for something to keep the scallies out.
We have wired PIRs and wireless door/window sensors (there's an Inovonics wireless extender next the main unit). I'd like to reuse these if possible.
Are there any installers who covers north London who could do this kind of install and give me the installer code too?
Cheers,
Justin
