Home Security Alarm System

castle_age said:

Hi,

I basically want to build a cost effective alarm system for my home with the following attributes:

1. Need to have 2 or more zones (connect to basic motion sensors)
2. Input of reed switchs would be nice
3. Needs to have output 3 12volt sirens
4. Needs to connect to 240v mains ac
5. Either a keypad or some other device or system to turn it on and off.
6. Time delay (to allow people to leave after turning on or turn system off when coming home - without the sirens alarming)

If anyone has any diagrams or guides it would be great

Thanks
