WHAT?? No no no, I am more than capable of installing mats BUT stopped
doing that 20+ years ago when new (and much better) technology appeared.
Trust me, I've installed more pressure mats than you'd believe. AND they
were concealed. AND we didn't cut the underlay!

You mean you installed useless technology? You've said on a number of
occasions they are unreliable and don't last. So you just took the money
and ran?

No, please read my posts properly. I said we used to install them UNTIL
better technology became available. Up to the late 70's it was usual to
install door contacts and pressure mats. Maybe the odd ultrasonic too. After
around 1978 though they were starting to be faded out. Understand me now?
What I am saying is that 25 years ago pressure mats became old hat in favour
of voluetric protection. YOU though still have mats!



As for relays, I made more circuits using those when I was at college
then you probably have but again, I dropped them in favour of better and
more reliable technology. That was 27 years ago and YOU are still using
them today. Says it all really!

You're definitely out of the IMM mould. Anything new is always better and
exclusively replaces older techniques - regardless.

When it comes to pressure mats, yes, indeed.


I've got news for you. Nothing replaced relays for all applications. And I
daresay you'll still find them in the finest alarm currently available.
