how can i make a fire alarm system? Answered

i want to make a fire alarm system for a low cost.


You just want "an alarm" then, not a fire-specific one.
All you need is to get the parts and assemble them, do you know where to get pull stations, wire and strobe alarms?


Those are going to be REALLY expensive!!!
Go look on eBay. I bought a FireLite BG12 pull station for $15 BRAND NEW
and a wheelock horn strobe + strobe for $15 all together too!
Then I bought a 12V AC adapter and I was GOOD TO GO :D
I built a PVC stand for the pull station and Horn + Strobe, ran the wiring inside.
It cost me less than $40!!!!
