Step 2Well that is perfect
The output from the circuit is 4.5V which is perfect to hook up to the battery connections of another magnetic door sensor which I bought from Dollarama for $1 CDN. hooking up the wires to the battery connections was the only mod I made to the sensor.
I tested the circuit and there is a little discrepancy in the alarm volume if S2 is closed the Alarm turns on and emits ~90db when S2 is reopened it drops down to ~80db not really a problem but worth mentioning.
