While I'm not a big fan of wireless alarm systems (so easy to jam) I've
got a situation where a sibling is wanting a new alarm and I can't be
arsed running wires around his house.

Are the modern wireless alarm systems any good these days? I've been
looking at the ones in Screwfix.

I recall that the early ones could be set off by the high level radio
transmissions of Taxi's. This is apparently a problem with the current
system which is a wired Optima Concept system. Normally the Optima
range provided stellar service, but the "concept" version tried to be
clever and mounted the full electronics in the remote keypad with just
the power supply and some circuit terminals in the main box. It appears
to be the interconnecting wiring that is prone to picking up RF from any
passing taxi's and setting the alarm off.

Anyone used the Yale or other wireless alarm systems from Screwfix?

You won't find any decent wireless alarms in Screwfix.

Erm, right.

Yale = bag of ****. Offerings from only decent wireless alarms I can
think of aren't readily available in DIY type places. Txecom Premier
and radio expander might be the best to go for for ease of use and
installation, reliability and availability.

Oh well. Hard wired it is then.

It's too easy to jam wireless alarms anyway. You can hack one of the
transmitters or even a matched keyfob to transmit at higher power
continuously and it jams the whole system. Even if it has an "anti-jam"
feature (sets the alarm off) the owner will soon turn the system off if
it just sits there in alarm mode continuously.

Nope, but I have used TLCs Infinite range. That does seem quite good.
Fairly pricey though.

Keep forgetting about those. THe Infinite is meant to be reasonably
good. FM Electronics do some decent wireless kit too.

Yale are crap. I installed one of these last year:

and it's worked brilliantly ever since - no false alarms and works when it
should do. Well recommended.

That should be easy enough to cure.

I wouldn't worry too much about the "jamming" problem. Only a very well
organised burglar is going to attempt to jam an alarm system and then
only if the contents being protected are of high value.
The large majority of burglaries in domestic premises are carried out by
relatively low-intelligence people who are certainly not going to carry
jamming equipment with them.

Yeah, if I rewired it all in screened cable!

I'd rather just put in a new system and avoid any repeat visits.

Not necessarily. You could try fitting ferrite beads to the wires
coming out of the alarm box to increase their self-inductance...

I get the feeling burglary has gone out of fashion since nothing is
worth much any more and people tend to take their phones and laptops out
with them

Not that there would be anything unusual in an 80 year old grandmother
in Middlesbrough being a crack dealer.

Hell, I've been in some pubs in Middlesbrough. Finding an 80 year old
crack whore in Middlesbrough wouldn't surprise me.

Not necessarily - a simple filter should do the business.

And if that was the case the contents would be of interest to the
insurance company who would insists on a grded alarm which you
couldn't fit yourself anyway.

I installed the Visonic PowerMax+ system. It operates in a frequency
spectrum reserved for security devices - 868MHz I think - which is supposed
to all but eliminate interference and false alarms.

Fully monitored system for tamper events and low battery warnings etc etc.

It's not cheap though - bought mine from www.quick2fit.co.uk
