I need help designing a homemade fire panel

Like what Wheelockns said I recommend using a (depending on the size of your home) a Honeywell Vista 15 or 20p panel. These panels can be configured for use as a security system and/or a fire alarm system. You can pay a company to install it for you, or you can install it yourself. If you choose to do it yourself be warned that there is some programming involved but there are many YouTube videos on it along with some topics on here. These systems can also be programmed to dial a monitoring station when there is an alarm condition and they can automatically dispatch the proper authorities. Hope this helps you!
