Oh so the bump becomes a dip instead of a bump! Oh please!

Hmm. Ever heard of packing something square? Of course judging by most of
the pro burglar alarm installations I've seen in houses, care and neatness
was the last of the priorities. I hope you're different, although given
the cost in time of concealing all cables and switches etc, I doubt it.

Doubt what you like but I can assure you than I have NEVER shown a cable on
ANY installation and that includes not only houses but industrial buildings,
shops, ships (yes, ships!) and even the odd Royal Palace.

Have you looked at them? Checked their condition? Is the foil and foam
protruding from the split edges yet?!

They all still work, so no, I've not done a physical check.

Ah, right. So, your waiting for the alarm to give problems and annoy your
neigbours jost like the professionaly installed systems which you mentioned
earlier?! Ever hears of preventative maintenance. It'll also be interesting
to hear what you do when your pads do pack up because (and I may be wrong) I
don't think you can buy them anymore! Most of the major alarm wholesalers I
know stopped stocking them in the early 90's. I think that says a lot?!!

Yes, if I did it for a living like burglars do!

Most burglars aren't pros. They are druggies etc looking for a quick buck.
A pro burglar would pick somewhere with richer pickings than my modest
pad.

You'd be surprised.

The PROPER locks will.

I'd love to see the lock which makes the surrounding frame etc stronger.
No locks will stop a determined attack on a wood sash window. I'm
surprised at you if you're in the trade.

You simply bolt the two halves of the sash together and they then cannot be
opened. Forced out yes but not opened.

As for securing the frame. Yes I agree - it's difficult. In th epast I have
used ally angle which the bead fits over to hide it. Very effective
indeedie!

To the best of my knowledge, non of the nearby systems that constantly
give false alarms have pressure pads. To install them *properly* is too
much work - as is fitting window and door switches *properly*.

It's nothing to do with fitting the contacts (or other devices) properly.
It's all about care of installation. Soldering joints, avoiding EM
interference, using proper clips - not a staple gun, etc.

I'm afraid you're coming across as so many other pros - you recommend as
gospel that which is easy to install.

You're totally wrong. What I advise is the best options. I have had very few
"easy fits" and have never been in the "cheap brigade". I have never
installed a system in a house - even a very small house - for less than
£500. Why? because I did it properly. I never had systems which troubled and
many systems I installed over 20 years ago are still working just fine
having only had the odd battery or sounder replaced. As a general rule I was
only ever called out to systems when something needed altering such as
customers replacing doors etc.

So please, don't paste me up with th evast majority of pricks who call
themselves alarm installers. I'm one of the few remaining good boys!
