Any recommendations for a diy burglar alarm for a scout hut. I thing I want
the dual microwave plus PIR sensors and a wired system 'phoning out via a
payg sim. 5 rooms including vestibule.There's nothing particularly valuable
to protect but once notified someone can be on the scene in seconds.

Assuming that it's not 0330 and the respondee(s) are not tucked up in bed
sound alseep... And what are they going to do even if they do get there
and find intruders? People caught where they shouldn't be tend to react in
a none to friendly manner. Citizens Arrest? Very, very grey area of law
and best avoided.

Think a bit more about what the plan of action is to be when the alarm
triggers. Have a look at sound bombs.

I guess that's true of any burglar alarm. In this case I've been delegated
to look at the problem , the decision to have an alarm has been taken. I
just want a cost effective installation.

I imagine deterring vandals is a major consideration.

Ours is a commercial installation but I am sure there are lots of DIY
jobs available. Screwfix for one:-)

You will need a door entry switch and the keypad to set and re-set the
alarm. After that you might be able to economise on PIR detectors if
entry routes are obvious. Phone home is beyond my experience.

Yes. The experience here with our barns and the cricket pavilion was
that entry was gained for solvent abuse etc. and fires set on their way
home. Noise at the outset would probably have saved the insurers.

What did they put in the cricket pavilion? I'm hoping to get away with just
5 dual tech PIRs a keypad/controller and the GSM dialler and have costs
below 300 quid plus a small amount of my time.

Note, your PAYG sim will probably expire after 6 months if not used,
so an occasional test call would be advised,

As often advised on here, most important is physical security.
(door/gate locks, window locks, door/windows/gates/fences properly
maintained, security lighting, etc.)

For the alarm, there are probably two significant aspects.
Firstly, making it a visible deterrent with visible external
sounders with flashing LEDs so they stand out at night.
That combined with good physical security basically says it's
easier to go and break-in somewhere else, so don't bother here.

Then, if the physical security and the visible alarm deterrent
fail, I think sound bombs are a good idea. They may scare off
the burglars before they do further damage. You really don't
want to meet them face-to-face though.

There are a number of things to consider which you haven't
mentioned. Such as is there anything stored in there which is
particularly attractive to steel (e.g. a room full of PC's).
Also, is the building in the middle of an urban residential
area, or out in the sticks with just one or two households
nearby? Do you have an insurance requirement to fit the alarm?

BTW, I wouldn't have thought a PAYG contract was a good choice.
You really want a permanent contract for something like this.
You could use a land line if the line is well enough protected
against being cut. If you're looking for a monitored solution,
then there are things like RedCare which will detect the line
being cut.

Cameras and recorders are now a lot cheaper. A notice saying 'you are
being recorded' with physical evidence of it being true might also be a
deterrent. It might encourage imntruders to burn the place down to
destroy recorded evidence of course, but casting doubt into even a
moronic brain might work.

We installed a "screamer" siren (audible for around a mile) on the
roof of our mountain hut, plus a loud alarm inside.
Someone smashed the locks off two doors and opened them.
Fortunately the alarm was one which reset itself even if doors were
left open. The sensor inside kept turning the siren on when they went
inside, and they left without doing any more damage..
The plywood I glued and bolted on the inside of the doors worked well.
Now we need better locks.

I don't know. I don't even know anyone who plays there to ask. Sorry.

Name for an extra loud sounder - usually multiple transducers.

Used indoors, to create a sound which is too painfully loud to
hang around.

Being slightly deaf and having a reasonably large house I use one of
these as my door bell sounder. It has two plus points, firstly I can
hear it anywhere in the house and secondly the person at the door gets
positive feedback that the bell push has worked.

If you have these as part of your alarm system no one will want to stay
in the same area as them!!

I hear tell that a Max Bygraves LP played at normal volume has the same
effect.

The soft equivalent of this

http://www.diy-alarms.co.uk/catalog/...roducts_id=299

Sound bomb 111dB
Master Blaster 127dB
Air Raid Warning Siren 135db

I fitted 3 in a soil lab. Testing them out was fun.
