Comfort - Alarms - Zones - Best Ideas.

[Wayne <wayne@xxxxxxx>]

Hiyall,
Having some mods done to the house at the mo with garage conversions,
kitchens and porches being created (and a LOAD of mess!), have took to
the idea of fitting an alarm - most probely a comfort (hay if it wasnt -
it just wouldnt be proper of me to post questions here :)).
Have got me some 6 core alarm cable to hand and started drilling holes
for cables got me thinking on how many sensors / cables are needed to
get a reliable system going. (nothing like planning things on the fly!)

The general 'gist' on reliability - or at least confirmed alarms - would
appear that it would best to have sensors on external doors /and/ pir's
in rooms, so if a window sensor was tripped AND the pir in the same room
- someone has got in and mooching about in the room. If you had either
(but not both) you could have false alarms based on some kid throwing
ball at window and tripping the sensor or if something fell in the room
it would trip the pir.

1st off - is that assumption correct? (did it make sense even!)
2nd can sensors in a room be chained together in some way or do you wire
each one back to the panel? (the garage for example would have 3
sensors, one for the outside door, one on the window and one pir)
3rd Zones - I would imagine that if you have window/external door
sensors you can 'zone' an 'I'm in but tell me if someone gets in while
I'm asleep' setting?
4th pvc windows / doors - whats the best sensor to fit with those?
vibration type?

typically I thought of a load of questions when I was drilling and now
have forgotten now that I've got round to typing this thing - although
the first two are key at this point!

Thanks for listening (reading)!
