He's not wrong though!

Nah, wireless is fine but the installers sound rubbish, probably why they went down.

Don't go to a solicitor .... that would only end up with a richer solicitor. Go see the Citizens Assassination Bureau for advise.

QFA

vodka + cold =

A friend of mine had a wirless intruder system fitted to their house in 2007 with monitoring. The system has never worked correctly from install ( by an agent for a national ) . There is no external ball box, the only sounder is the internal one from the control unit fitted into an upstairs wardrobe. It cost

vodka + cold =

no.

no vodka and it is warm here right now.

check this thread for an explanation why wireless is rubbish:

Explanation

Wireless Grade 2 properly installed = PD6622 Grade 2 installation suitable for low to medium risk and police response.

There will be few members of the public visiting this site who require greater than Grade 2 systems.

Of course wireless is not suitable for Grade 3 or 4 because suitable components for the grades do not yet exist.

hmm - would it make wireless system automatically better if it would be approved to G3?

also - low to medium risk grades expect the possible intruder to have little or no knowledge of the alarm systems. question here is: is knowledge of using a wireless door bell considered a little bit of knowledge or no knowledge?

me thinks the G2 is too high approval for wireless equipment. ofcourse as it is approved it is OK to use it in G2 installations

Of course wireless is not suitable for Grade 3 or 4 because suitable components for the grades do not yet exist.

wired components and panels for G3 and panels for G4 exist.

if i remember correctly there is a time limit for the alarm to be registered at the panel after the detector activation. if there is RF JAM present wireless won't be able to fill this requirement. so i guess it will never be G3 or above..

Of course!

Old 433 frequency maybe because more equipment on that frequency but personally never come across it and with 868 even less likely. I have systems in property with wireless doorbells, wireless broadband and in one case nearby radio ham - absolutely no problem. Radio interference is more likely to cause a false alarm on a wired system than a failed alarm on a wireless one, that's why several companies exist on income from the sales of RFI filters for wired alarm systems!

Not sure that will ever be the deciding factor - of course wireless signalling is available to the highest grade, Grade 4 through Redcare and Dualcom so those that make the decisions must have confidence in wireless.

To be honest from reading your post it's hard for me to see what the dispute actually is, I'm not saying you are in the wrong or that the ARC are in the wrong but you haven't really described what the ARC are claiming for.

You haven't actually said who wrote the letter about the
