The sensors in smoke and co alarms work best in temperatures between 40 f 4 c and 100 f 38 c.
Smoke alarm in attic.
I was told of an inspector that said a wireless smoke alarm should be put inside an attic to just lay it down presumably near the hatch.
We do not recommend installing smoke or carbon monoxide detectors in unfinished areas of the home.
Place additional attic smoke detectors on the finished ceiling as before installing one every 25 feet in an open space.
Another location in a home where you should have a heat detector rather than a smoke alarm is the attic.
Smoke alarms are not designed for garages and attics and are much more likely to fail than a heat detector.
An ionization smoke detector smoke enters a chamber and interrupts an electrical current which triggers the alarm should be installed no closer than 20 feet from a cooking appliance and no.
If you sleep better at night with an attic smoke detector they do make detectors for extreme temperatures.
They go from 15 to 200 degrees fahrenheit.
Also was not mentioned was whether it was an unfinished attic or finished attic.
Smokes are very sensitive to dust.
The us fire administration fema recommends that you have a heat detector rather than a smoke alarm in your garage.
The only problem with these is the dust in most unfinished attics.
This includes attics crawlspaces garages unheated areas or porches.
If you have a workman in they will stir up the insulation and create dust.
