well, i want to make a thing u pull to make a alarm go off. just not to loud to call the fire-department
Basically what you need are three things.a power supply (usually 12 V, try an AC adaptor)a Pull station (the thing you pull to set off the alarm. you can use a switch) Check eBay, I bought a FireLite BG12 for $15 new! I also have some older ones if you want)a signaling appliance (the actual alarm) you can get a 'horn' or 'horn/strobe' unit. I recommend the ones made by Wheelock. Those can also be found for cheap. There's also stand alone strobe units. I have a lot of extra ones that are new or like new, so let me know if you're interested in buying some. I can arrange payment via Paypal for security.
