We have no such thing as a smoke certificate in my market. But my response would be simple... call the agent and ask their client to replace the battery to ensure the unit is functioning properly.

I have packages of 9 volt batteries

Nothing. Go to closing, and repair or replace the detector after buyers move in.

We don't have that in our state it's our responsibility & the sellers to have that stuff working at close. I'd tell the LA that it needs a new battery & nothing would happen.

Just wait until after the closing and change the battery.  No big issue, besides a replacement is not expensive.

Needs a new battery ?

Write it on the final walk through form, have the buyer sign it, submit it to the listing agent. Close Escrow.

In California we have a final verification of condition(final walk-through form) and I would likely include it there.   I have never heard of a smoke certificate in our area issued by a fire department.   

We do not have any certificates issued by the fire department for smole detectors. Sounds like another government shake down. What is so difficult about either changing batteries or the smoke detectors?

Replace the battery.

Buy a battery and install it they are not that expensive.

I am with Nina Hollander on this one. I also carry batteries in my car. I'd change the battery to see if the chirping stops. 

Go to my car and grab a battery then install it.  If it is still chirping then we have a bigger issue. Time to call the listing agent.

Ask the listing agent to change the battery if you do not want to do it yourself.

Lyn Sims nailed this one!

Sorry we don't have that in Texas.

No smoke certificate here.  Is this something that your buyer does for himself, being thorough inspecting the home or is part of regulation in your state?  I would ask the buyer what he/she likes to do. It's likely that the battery is low but we cannot be 100% certain.  If the buyer thinks that it's ok and would like to proceed with closing then we will close, if the buyer is having a fit and wants seller to fix prior to closing then I'll prepare an amendment.  Also I don't usually change the smoke detector's battery as usually I can't even reach it. Many higher end homes in DFW have high ceilings even one story homes. 

Perhaps the battery needs to be replaced or the smoke detector needs to be replaced.  We do not have "smoke certificates" in my area.

Eeezy peezy - call the listing agent and request the batteries to be replaced by the seller. We don't have the smoke cert like I remember from back in Boston but they are still supposed to be in working order, as are the Carbon Monoxide detectors

Get the battery changed.

No such an animal in this market

We don't have smoke certs in my area. I would buy a package of batteries for my buyers. 

Probably wore the battery down during testing, stick a new battery in.

Inform the agent, but I would spend 3 bucks and put in a new battery.  If that didn't work I would thin about it. What is it really going to cost to replace.

I would put a battery in the smoke detector. Time spent = 2 seconds. Price spent = $2-3, actual value = priceless.

Chirping is usually low battery. I would discuss at the closing.  Good luck Praful Thakkar 

Nina has the perfect answer for this one...Praful.  A

No fire department inspections here.  If the battery dies after the inspection, that's life and better for the seller than during the inspection!  I'd ask them to replace the battery (or do it myself).

Out here we have to use the sealed from the user smoke detectors with 10 year non-user replaceable batteries in new construction.  Cost three times as much and when it goes out, the whole unit needs replacing. 

Change the battery. My husband and I carry some with us for this very purpose. 

It never happened to me, but I would not let my client to be upset about one tired battery. 

Ask seller to change battery?

I agree with Nina Hollander and call the listing agent to get the batteries replaced and/or repaired.

Never assume in real estate--get company back out

I would have the battery replaced before closing... to be sure that is the problem.  Matters not whether it is you or the listing agent.  Whatever is most expedient to be sure closing occurs on schedule for YOUR clients.

have the homeowner replace them.... hold back at closing to cover the cost in case it's defective equipment!!!!

Ask the listing agent to replace the battery.

I agree that it is probably a low battery and that can very easily be fixed.  On a Final Walk-Thru I would do nothing Praful Thakkar. 

Change battery however...I had one that would not shut off no matter what and I had to call out of state, track down the inventor and he walked me through a series of steps that shut it down...Amazing. Claimed it was a defect

Praful Thakkar Ask the the seller's agent to bring a battery to the closing.

We had that process in SSF, but nowhere else, so I rarely dealt with it. Call & have them change the battery before closing or maybe give your clients an battery as part of the closing gift?

call the listing agent.

No smoke certificate required in my market, but since it is not waorking as intended, I would ask it be repaired!
