The following links are diagrams of various Alarm Related devices I created over the years of installing alarm systems. By no means do I gaurantee the originality of the idea nor that it will function for you as intended. Your usage of these ideas is totally at your own risk.
Mini-Alarm System - This was created originally for use in a motor home where the owner wanted it to be protected while sitting in their yard but a conventional auto-alarm wouldn't do. This device has an exit delay, entry delay with pre-warn buzzer and the delays are modifiable just by changing the timer settings. In my real installation the system triggered a wireless transmitter that would setoff the alarm in the house as well when the motor home was in the driveway. The Altronics timers used work flawlessly for this purpose and this system has been in use for about six years now. Timer 'A' serves as the Exit Delay timer and Timer 'B' serves as the Entry Delay timer. The 2.2k Resistor is used so that the Pre-Warn sounder during the Entry Delay is softer than an alarm condition. You could use a siren for the alarm condition and buzzer for the Entry Delay if desired with little modification. Also, the motion detector could be replaced by any other type of sensor so long as they are Normally Closed devices.
