volt pen is not the same as a volt meter low voltage ???

 

A digital volt meter.

 

yes --fluke to be percise

 

Are there more smokes somewhere else? Check for voltage on the interconnect wire. 9 volts dc

 

Today's service call:

HO removed a dwelling smoke detector because it was beeping. They replaced it with an identical unit, and it still kept beeping, so they just removed it and pulled the battery out.

I arrive and can't tell which smoke is the old one, and which one is the new one. So I put a known good battery in one, and install it.

It beeps every 10 seconds or so. OK, so I pull the battery out and install the second smokie. Again, it beeps every 10 seconds.

My volt pen says there's power.


What next?

At this point for me, the next step would be to give the Estwing treatment to both smokes. :whistling2:






Actually, I always make sure to use the test button. This often "resets" the smoke, and the chirping stops. Also, I try a fresh battery. As well as ensuring there is actually 120v, and the spices are secure.

 

Are all of the smokes periodically chirping or just the one?

 

Just the one in question.

 

Loose neutral.

 

That was my first thought. So I pulled the mounting plate down and checked the connections. All 3 were good.

 

I think someone already got it. Hold down the reset button until you get them all going off for 15 seconds or so. This usually does the trick!

 

What reset button? I've never seen a smoke with a reset button.

Some have a ShutTheF*ckUp button, but reset?

 

You said you didn't know which was the new smoke, did the battery have a proper connection? Meaning, if it's the old smoke the tabs might be jacked up?

 

When I arrived, I have provided with two identical smokes. One was original to the house wiring, and one that they purchased in hopes to solve the problem. The new one didn't solve the problem.

New battery installed in both, and they both beeped every 10 seconds or so.

 

test button

 

Be honest, how long did this call take you, not including the 800 mile drive? I won't laugh if you say four hours.

 

I never looked at a clock, but I'd say 10 minutes or so.

 

how about another hint.

(sorry, it was a very long day and my brain doesn't really want to work overtime.)

My brain doesn't work undertime some days, either. :laughing:

Another hint:

When installed, neither smoke signalled the others when the test button was pressed.

What is on the circuit that is feeding the SD?

Beats the cheese out of me.

 

What is on the circuit that is feeding the SD?

 

If it's just some bedroom lights that shouldn't make a difference. What's your take here?

 

Did you change the harness too? Or just swap detectors?

 

Just swapped the detectors. They were the exact same make & model.

 

I have had some weird things happen with firex (don't know what brand you are working with). I know it sounds wierd but we actually had a service call where we changed another one out down the line and it actually made the other one stop chirping. Also if one is a co2 combo that would be where I would start. Smokes can be a pain to troubleshoot.

 

Birds nest above SD box?

Or a loose neutral in the box feeding it?

But some smokes will beep constantly once they lose the grounded conductor, not just chirp.

 

Interconnect is no good, smoke alarmed due to interconnect but doesn't know to shut off now.

 

Houston, we got a harness issue.






:blink:





Right?

 

Did I miss something? Did you fix it and not telling us what you did. :001_huh:
gus

 

See post #1.

Bad harness?

Houston, we got a harness issue.
Right?

No.


FWIW, there is a response that is close, oh so very close, to the actual problem. But it's not a complete correct answer.

 

My guess that something give out the high frequity like remote control or a electronic ballasted luminaire { it can be either flourscent or low voltage with electronic transfomer }

Merci.Marc

 

I've had similar symptoms with mis-wired interconnects. 120 Volts on the red line, etc.

Usually, the affected smoke is fried, and won't talk with the other smokes after such events ... :no:

 

It's the doorbell thats chirping:thumbsup:

 

ok we give up

 

I gave up as soon as I saw the title to the thread. :laughing::laughing:

 

I'm thinking you had no 120v present. I found one once fed by a switched receptacle....on the switched side.

It worked great as long as the switch was on. :thumbsup:

 

Did you silence all the other smokes?

 

No 'silence' button.

 

Will the alarm in question sound if the test button is pushed on one of the other alarms, and do all the others go off? What are the LEDs doing and what colors are flashing?

 

If I pushed the test button on the one I was replacing, it would sound, but none of the others.

I pushed a test button on the smoke in an adjacent room, and they all sounded except for the 'problem child'.

I never paid attention to the LED. Sorry.
