This is more like it. Thank you Frank.

I will be out of range of radio gear so a cell phone connection is a
must. Your comment about motion sensors and heat is an interesting one
that I haven't heard before. I've already got a quote to install mains
but the 2ftx2ft brick box they want to put the meter in requires ANOTHER

  planning application which can and usually does take up to 8 weeks.
Once the mains are in I will be doing it properly but meantime I need a
cheapish foolproof thing that will work. Door sensors and a siren will
do it because I intend to put another welded gate inside which will give
the time needed for someone to get there. I had envisaged using motion
detectors because if they turn up with oxy-acetylene, bang goes the time
buffer.

Can you give me specifics? What I need and where to get them?

FYI I'm building an activity day center based on archery. I can't turn
up on the day with 50 people and find no equipment. It just doesn't bear
thinking about.

Thanks again.
