I called ADT about the heat sensor and am getting one installed in the next few weeks (soonest I could get a tech out). I asked about the false alarms with the smoke detector and finally got a straight answer. They are VERY sensitive to dust and if a spider decides to spin a web on one overnight, that will wreak havoc too. REALLY!?!? When changing bedding (which I explained), dust is going to fly a bit. I don't remember whether the false alarms were the day after changing bedding or not but either way, not the best for that situation. Heat detectors aren't my favorite option but they at least protect my house if something happens.
Bottom line - prevention is key. Once you have a fire, unless you have a sprinkler system, the fire department isn't making it out there in time. I would like to know more about these pop bottles though. Sounds like it just might work. I figure with GFI outlets, once something starts to meltdown or short, power is going to get cut so if they would put out the fire quickly before it has time to spread, that just might work. One last thing, does anyone know how hot melamine can stand?
