Smoke alarms

[guschash]

Where in the code does it talk about smoke alarm location or doesn't it. Do we have to put them on arc- faults. Read 210.12(A) and 760.41. I think they need to be but not sure.

760 does not apply to 'Smoke Alarms'

 

[guschash]

No wonder I didn't find! I was reading the explaination in 760.41 and it mention smoke alarms. Telling you to go to 210

Smoke alarms or smoke detectors? The line voltage smoke detectors must be on afci, in dwelling units, unless you have an amendment to that. The code on smoke detectors can be found in the building code not the NEC.

Aren't the line voltage types called smoke alarms?

Thanks Dennis, I thought it was in the code. What is the differents in alarm and detector? I talking residental. Does a detector give off a alarm if it detects smoke? Whats does the alarm do if it detects smoke? Trying to learn something here.

Well many people call them alarms I should have made sure you weren't referring to fire alarm panels. That was my bad...

I'm under the impression that a:

Smoke Alarm is line voltage or battery type that can be or is interconnected and is the alarm itself.

Smoke Dectector is part of an Alarm System, to detect smoke / heat to set off the System.

That is correct as far as I know.

If yopu want to see where and how to install, look at NFPA 72.

Smoke alarms are in the building code, and I'm not sure if they are in the resi code.

Smoke alarms are the battery or line voltage detectors that have a built in sounder - the alarm.

NFPA 72 2010 3.3.245 Single Station Alarm. A detector comprising an assembly
that incorporates a sensor, control components, and
an alarm notification appliance in one unit operated from a
power source either located in the unit or obtained at the
point of installation.

Smoke detectors are are the low voltage ones that only detect smoke. The "alarm" is a separate audible/visual that is activated by the fire alarm system.

NFPA 72 2010 3.3.59 Detector. A device suitable for connection to a circuit
that has a sensor that responds to a physical stimulus such as
heat or smoke.
