This came from legislation:

""""smoke alarm" means a device designed to detect and alert occupants of a dwelling unit to visible and invisible products of combustion by means of an audible alarm."""

Now if you were required to enforce that in a house, what type of device would you require??????
 
and if you had to require a specific device using this spec """""visible and invisible products of combustion """"

any different answer????
 
Chihuahua. They're tough to tape to the ceiling but they make plenty of noise.

Carbon monoxide is one of the "invisible products of combustion", so this definition could be construed as requiring CO detectors as well as smoke detectors.
 
I believe the OP was referring to just smoke alarms. If you traded "smoke alarm" with "CO alarm" in the origonal post, the definition would probably be the same.....as you stated. I wouldn't require a CO alarm using the definition for a smoke alarm, though.

Using the definition above it should be a combination ion/photo smoke alarm (detector).

Ionization detectors respond to invisible by-products of combustion. Photoelectric detectors look for the presence of visible by-products of combustion in the detection chamber.

Water and carbon dioxide is most always present from combustion, carbon monoxide is a product of incomplete combustion.

A combo smoke and Co is what I thought

I have one definer saying it means a combo photo and ion alarm

Could double as a limited area sprinkler system. I would check with the homeowners insurance for a discount.
 
[F] SMOKE DETECTOR.


A listed device that senses visible or invisible particles of combustion.

The definition in the IBC commentary explains the two types of detectors for invisible and visible smoke; ion and photo respectively.

The IRC Carbon Monoxide Alarms commentary describes co as an odorless, colorless and toxic gas.

Forgot to say in my previous reply that carbon monoxide can be present or not in both visible and invisible products of combustion.
