I have seen some videos on youtube of people making their own fire alarm panel using light switches and relays. I want to do something similar with a light switch for the power on or off for the system, a switch for silencing the alarm, and one for drill feature. How can I go about doing this? Thanks for the help. This is for my fire alarm board, so it is not a commercial system and just my hobby board. Here is the video with my vision.
