In my dorm, the fire alarm is really sensitive toward smoke. I know I'm not allowed to have toasters. This is where I live though. No one is going to tell me what i can or can not have in my house!
I've not heard any of them yet. But following parameters should be checked b4 purchasing. dB : this value should be greater as best. impedance : as low it is great frequency: short range will sound more clear, e.g. 20 Hz-20k kHz will sound gr8 than 18 Hz to 20 kHz. sensitivity..great as good. Hope it help ya.
You can't extinguish grease fires with water. You have to use carbon dioxide or baking soda. The contents of a fire extinguisher are under pressure.
