Setting it off is a good idea unless it’s co detector. Timing the beep and maybe glass on the wall is good.

A/ Drill holes, fill the void with squirty foam
then - if you can still hear it . . .
B/ Trigger an EMP to kill the electronics . . .

Destroying a whole marina full of nav gear to destroy a 99p smoke alarm may make you a tad unpopular!

Sell the boat.
If it is a fire alarm and you have no panel it will be battery. If it is on a panel, trace the cables.
They are a pain to find, when hidden away.
I guess you can not isolate it to an area?

RF spectrum analyser is a possibility, but battery powered and low power means its going to be very hard to track down, and require an very nice setup, probably £1-5K of kit and a lot of effort..
Time to start making holes...

A friend of mine bought a little box off of Ebay that would emit a beep at random times, we hid it in our boss's office. It drove him absolutely demented 
. Watching him stalking around the office waiting for the next beep was hilarious. Any chance someone is playing a joke on you?

I was fixing the vandegraph gen at a school once. The head of physics wasn't too chuffed as id been repeatedly rebooting the projector in his classroom (which shouldn't have happened, but certainly was happening!)

I would suggest recording the time whenever you hear the beep.
After youve collected a load of data, it may well be that you can find a pattern.
All this then means is that you can be listening out for when the sound goes off. This way you will be able to track it down without too much effort, it will just take a while.

i believe a smoke bomb will set off your alarm
seal your boat up and use a smoke bomb it should set it off
but wont leave your cabin full of a burnt smell after
you will need to go inside it though so beaware of this
enjoy your garden air hose to find an alarm time though

Buy a smoke alarm, stick a duff battery in, tape a lump of cheese to it.
Hide it, let it bleep, let your dog try to find it. He will.
Repeat.
Put hungry dog in boat.. wait.

Maybe buy/borrow dog first.

I've had battery smoke alarms give out the odd cheep when the battery is low even the mains fed smoke alarm has a back up battery ......that one was hard to discover .
I've also discovered .....cheep type noises from the central heating remote control thermostat . a TV control , a couple of digital timers . a battery supported mains voltage failure device , my phone . The electronic control on the water filter , gas monitors & CO2 detectors . The water level detector in the caravan flush tank drove me crazy before I discovered what it was & where it was & a couple of oil tank fuel level indictors . Does your mobile phone signal that it's lost the ability to receive a working signal .
Don't go ripping the boat apart just yet .... if you're like me you'll be hearing damaged more in one ear than the other so directional hearing becomes complicated . even with both hearing aids in use.
Rule out everything before you start wrecking . Using a bit of sink drain pipe as a listening scope might be useful if the noise is fairly regular .
Suggest you remove all such battery powered stuff clean the terminals with cotton buds & vodka & put in new batteries after first cleaning the ends to remove the super thin protective coating they have.

Set out an imaginary grid on the wall of interest, then every time it goes off use one of these
Each time it goes off go to the next square on the grid. You’ll be urprised how accurate it is.
They use this technique to detect water leaks in buried pipes

If you don't want to ruin the T&G just drill a few holes from the outside like i did, then claim on the insurance when it sinks 
A friend of mine bought a little box off of Ebay that would emit a beep at random times, we hid it in our boss's office. It drove him absolutely demented
When I was living at home my Dad said to me "You'll be up early tomorrow", he knew I was out on the lash that night. I laughed it off but he had set an alarm clock and hidden it in my room.

Ok I'm trying to avoid ripping out lots of 1/2" tongue and groove, to find a small concealed electronic device on my barge.
It randomly emits loud bleeping noises, the volume and intensity comes and goes.
It is loud sometimes, and driving us mad.
It is impossible to hear where the bleeping is coming from, just that it is somewhere behing a large area of panelling.
A normal builder's batten detector is no good, it's an old iron hull and there are millions of random battens, fasteners etc behind the panelling.
I'm fairly sure it must be a left-behind fire alarm, gas detector or similar sensor/alarm.
This means it must have electronic currents flowing, and a quite powerful loudspeaker. But it's going to be made of plastic.
Are there any gadgets which could pinpoint it? That could detect the electronics or speaker in the pesky thing without me tearing out loads of t+g?
Preferably available on ebay, not something that Q would issue to James Bond. Although it might be worth it!
A penny for your thoughts chaps this is uncharted territory to me.
( PS the previous owners were swingers, I hope it's not a camera)
“For Sale: one faulty CO alarm.
gives off an annoying beep which is giving me a right bloody headache..!”

this sounds a bit random why would any one put a fire/carbon detector behind a t&g wood whats the point ?
more lightly you got a battery item that is getting low in an electical item
years ago we had a beep that started in the front room seamed random it would beep every so often days turns out it was a watch that was in a corner that son had put there for me to change a bettery in but the alarm was set for 1 day in the week only found it when was cleaning up one day
before ripping out out anything clear the room inc anything not nailed down
