FCI, Gamewell, Silentknight, Fire Lite or any others?
A simple and easy to use fire arm would be a 9mm handgun. It will provide good protection and fires with great accuracy. Also many rounds can be fired in quick succession
Yes, and be sure to wear your tin foil helmet ZZZZZZZZZ fiZZZZZZZZZ Oops, maybe not such a great idea if the cord can get pinched and slowly heat up the insulation with no ventilation eventually leading to a short or worse a heat condition that burns the insulation and sets the mattress in FLAMES AHHH FIRE FIRE GET OUT !!! you'll have to let it hang out, while it is off you can hide it under the blanket? just don't trip over the thing.
I would place the smoke detectors on a lighting circuit. Lights that don't come on are more quickly noticed than unused outlets that don't work.
by the NEC smoke detectors needs to be in a dedicated circuit, is rare but some states and some inspectors wants them in an arc fault breaker, the book say that, but some times they don't ask for it. is too expensive to buy an arc fault breaker.
