Inspired by the other thread.
I'm building an addition onto my home. Interconnected smoke alarms are now required in our area, so I'm doing that - including running them into the existing house.
A few questions.
Battery Backup - I see plenty of AC wired interconnected smoke alarms that have individual 9V battery backups. Considering how many alarms there will be once this system is done, changing them twice a year will be a real PITA. It seems there should be an easier way - like an UPS type battery backup on the entire circuit. Is anything like that available? A few minutes of googling didn't turn anything up.
Of course, if the circuit gets broken somehow, everything downstream would be dead. Maybe keep 9V batteries in the bedrooms also.
Attic Alarm - The specs I've looked at tell you that the alarm is only rated for 40F to 100F. I have a metal fireplace chimney going through the attic, and I live in a wildfire area, where fires can start with sparks through vents into the attic. I've also heard of lightning strikes or wiring faults causing fires in attics that can smolder for days undetected before flaring up. So is there a detector that you can put in this type of space? I've seen the heat detectors - but would that catch a slow smoldering fire?
