Ears are the best fire alarm detectors. Installation is usually natural process and should not be meddled with. Keeping someone in a confined space as there is a false ceiling might require to look at other regulations.

If nobody needs to detect a fire alarm the use of fire alarm detectors might be deferred until the need of such arises.

Mind that an above ceiling detector might also be referred to as below ground detector dependent on the floor plan.

If in doubt reading the code might be the preferred way of dealing with this question.

"If nobody needs to detect a fire alarm the use of fire alarm detectors might be deferred until the need of such arises."

What if fire starts from there? Does it need to be detected or not?

Wrong question. We are not talking about fire detection but about fire alarm detection.

Confined spaces with fire detection should be inherently coupled with a fire suppression/sprinkler system.

Some deaf will not noticed.

Most codes require that the "alarms" be bot AUDIO and VISUAL.

Your question makes no sense to me.

Please explain the non-availability of a copy of NFPA72 at that location. The question is abstruse.

Dear Minsahib, I am not possesing sufficient funds to pur-chase the said document and also my friend Siva is not been having this document NFPA7. We are making business and simply require your free help to make money to be rich like you.

Mr Idea Smith, can yo give me a drawing for the below ground fire detector and a full explanation as to how it works and who can supply this to me.

We thought the question was polite and recherche.

The NFPA documents have to be purchased. You might check with the county Building inspectors office they may have a copy you can look at, are you in the US? If so what state to give you an idea of where you need to go to check on the codes most likely the Fire Marshal or County Building Inspector.

I already send the necessary documentation to an anonymous account. If I do not receive full payment within the next 14 hours the package will anonymously self-destruct.

We talking business here so politeness is of utmost importance.

Thank you Mr. Idea Smith. I have your package and soon I send the money with with Mr. Siva and Western Onion. Please do not self destroy until we install the detectors.

You are so kindly person.

<...require your free help to make money...> That might be the real problem.

If you are in the USA just go to the local fire station and ask them. They will help you and are always keen to assist to save them hassles when they do the final inspection and when the place goes on fire. They always seem happy to be involved when I work there on converter stations.

Exactly.

Do you know what a firefighter calls a good day?

Sitting around the station, bored as F--K because there have been no calls, and all the regular maintenance on the equipment has already been done that day, TWICE, once to insure everything is in perfect working order, then again later 'for fun.'

Firefighters and police both have the same word for a bad day, 'exciting.' Excitement means there is trouble, (for the firefighters, that means a fire), trouble means someone has either been hurt or is likely to get hurt.

What's a 'fire alarm detector'? Do you mean 'ears'? As in, I hear a fire alarm...

Perhaps you mean smoke detector, or CO2 detector? In which case, they need to be located where they can detect smoke or CO2, not hidden behind a ceiling where the smoke or CO2 might not get to them quickly enough.

Fire detectors are usually installed in air ducts vents and supply

Here are some questions an experienced fire protection engineer might ask you when you hire them to assist you:

- What is the facility use classification?

- Is the facility existing or new?

- Does the facility have a sprinkler system?

- Is the above ceiling area sprinklered?

- Are there any combustibles in the above ceiling area?

- Is the above ceiling being used as a plenum?

The above is not a comprehensive list....

LOCKDUKE had the best answer-ask the Authority Having Jurisdiction (AHJ). In most cases it will be the the local building department, although when I lived in NYC, the Bureau of Fire Prevention was the AHJ, and sometimes satisfying the Fire Code involved obtaining documentation from theBuildings Department.

Regardless of what NFPA or any other Code may say, sometimes the AHJ will overrule it in its own code.

As to going to the local fire station, the firefighters do not necessarily know all of the requirements for every system, Their training is specifically oriented to control and extinguishment, and they are usually pretty damned good at it.

As far as cost of Code and Standards goes, if they are purchased for your business, thie cost may listed as a business expense, an partially deductible on your taxes.

I think I've shared this valuable "secret" before in another thread; i.e., the entire collection of 300 NFPA Codes and Standards is available online for free, only catch is that it's for viewing only, no copying, no printing. My personal thanks to the NFPA for providing this essential service free to all interested parties.
