Massachusetts code on smokes


I was planning on adding smoke/CO detectors to a general 15A lighting circuit. Is this code compliant in MA or do smokes need a dedicated circuit?

Massachusetts code on smokes


Hey,
I am doing the same thing currently. I believe that they do not want them on a dedicated circuit because if it trips you may not realize. If it is on a circuit with lights, you would know the circuit tripped from the lights. I am planning on using the three way hall light to run the smokes. May want to still double check. If you find anything out post it back, cause I am curious, but that it what I have been led to believe.

Massachusetts code on smokes


I have always thought they do not want them on a dedicated circuit, since they could then be shut off
I've been looking for something that fulle explains requirements
Its a Fire Code regulation as far as I know
Not even Mass Gov had info

Some info...& info on different types of detectors - from REMax
I may end up buying different types for a good mix of detectors

527 CMR 32 outlines requirements:

http://www.mass.gov/Eeops/docs/dfs/o...red/527032.pdf

But doesn't address the issue
When my last house was sold I think the Lt that did the Inspection stated they could not be on a dedicated circuit
I had battery operated & they wanted hard wired


Another pamphlet

I'll call the building office this afternoon.
A friend that lived in Beverly, MA was required to wire his on a dedicated circuit but it might have been a misinformed inspector.

Maybe not....but just info from a commission:

Start on page 18 (by pamphlet)

http://www.cpsc.gov/LIBRARY/FOIA/foi.../acfismoke.pdf

Quote:
NFPA 72 addresses the installation of smoke alarms in residential homes. The 2002 National Fire Alarm Code, Section 11.6.3 AC Primary Power Source, states:


The ac power source shall comply with the following conditions:

(1) A visible “power on” indicator shall be provided.

(2) All electrical systems designed to be installed by other than a qualified electrician
shall be powered from a source not in excess of 30 volts that meets the requirements for power-limited fire alarm circuits as defined in NFPA 70, National Electrical Code, Article 760.
(3) A restraining means shall be used at the plug-in of any cord-connected installation.
(4) AC primary (main) power shall be supplied either from a dedicated branch circuit or the unswitched portion of a branch circuit also used for power and lighting.
(5) Operation of a switch (other than a circuit breaker) or a ground-fault circuitinterrupter shall not cause loss of primary (main) power.
Exception: Where a ground-fault circuit-interrupter serves all electrical circuits within the dwelling unit

It would be a Massachusetts ammendment. NEC allows it to share a branch circuit.
(4) would have been easier worded as:
"AC primary (main) power shall be supplied by an unswitched branch circuit."
I Forgot it is Friday and the building office closed at 12:30. I'll update this thread on Monday.

I am also in Mass. Check with you city/town FD. We require them to be on a general lighting circuit so that if it trips you will know about it and will likely fix the problem as opposed to shutting it off and forgetting about it.

Following up finally.
I checked with the electrical inspector. He told me dedicated and it was code. I'm debating if I should challenge him on this. I don't want to tick him off but I'd rather the smokes be on a lighting circuit.

Edit: I'm going to check with the local FD. Who should I ask for? I don't imagine that all firefighters would have this info.

Why would you like them on the lighting circuit? The battery backup will beep when power is lost to let you know.

The reason I was told that they didn't want them on a dedicated circuit:

It could trip or be shut off
Batteries could be removed if someone had nuisance alarms & did not want to buy new smokes
If they shared a lighting circuit less chance they would be shut off
That was over 7 years ago at my last house
Didn't matter to me....I just wanted to wire them up & be done

Good point, follow the path of least resistance.

Mine (both houses) are on a lighting circuit
A dedicated just seems like a waste of a breaker
