This +12V can come from a key switch, a push button switch, a toggle switch, or anything you like as long as it applies +12V to the opto-isolator. Zone monitor schematic [ 43 ] Building the Hardware The following photograph shows the completed PCB. Assembled two zone input PCB You will notice that I have used sockets for the ICs. This is not strictly necessary, but when I build prototypes, I use sockets until I am sure that the design will work. Also notice that the rectifier diodes D3 and D4 are raised off the board.
This is a good place to put a key switch that turns off the alarm. There is also hardware support for a second key switch, so you might want to install one by the kitchen door to the garage. The outside door and inside door can be protected with standard magnetic door switches. As part of our layered-defense strategy, I would also put a door sensor on the door leading from the kitchen to the dining and living room area. This increases the chance of catching a burglar who has defeated the window or door sensors.
The other resistors are 1 percent tolerance resistors; so, three decimal places are required. So, brown, black, black, and brown means, (1 - 0 - 0) x 10 with a 1 percent tolerance, that is, 1000 ohms. There is no need to use 1 percent resistors in this design. I had them in my lab stock; so, I used them. You will also note that the white connector hangs over the edge of the board. This is to make it easier to attach the connector when the boards are stacked during the final assembly. [ 47 ] Building the Hardware Connecting devices to the board Congratulations!
