This is possibly the smallest smoke detector available. The body is based around a sandwich of the sounder and detection cavities with the control PCB and battery taking up the rest of the space. The resin covered area seems to be for protection against humidity. The covered circuitry is the sensor amplifier and the control chip (probably a microcontroller) which may just be standard SMD devices.
I forgot to mention that the test button on the side also acts as a mute button in the event of a false alarm.
Disassembly of these is pretty much a one-way trip due to the gluing of the sounder and detection areas.
It's a good idea to replace smoke detectors every 5 to 10 years depending on how much dust they get exposed to.
It appears the Cavius range also has a heat detector version which uses a thermistor to detect a sudden increase in heat or an upper alarm threshold.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

This is just a rebranded First Alert P1000 smoke detector
I like this small one and sound it produce but I cant find any available in shop and e-shop here in that time(they are in sell with same look but other brand also). I bought Hütermann F9 with standart sound. I like red blinking ring on it but not like battery can't be change not look like it can be disassemble without completely destroyed. Plastic look very cheap and poorly fabricated.
Thank you sir
Would you have any uses, for an out of date Carbon Monoxide detector?
i saw a video of kids sleeping through smoke alarms and not waking up and a company made a smoke detector that you record your voice and helps kids to wake up
That cavius smoke detector is a rebranded First Alert Adim and the other smoke alarm is a Status smoke alarm Wich I have in my collection
These buy the way work and work very very well but having a sealed battery (Which more and more smoke alarms do these days since modern 9V cells last for 10 years since people forget to change the batteries every year or even few years in the older ones which are much more power hungry!) you will need to replace them every 8 to 10 years!

CAVIUS are the original the others are ones that CAVIUS makes for other brands using their IP and factory for a fee!!!

That's a knock off of the first alert atom knock off I say knock off
thenks Clive
A lot of the new fire alarms have the sounders in the smoke and heat detector
Put the tools away, screw it on to your belly and let your rumbling sumac make it fall apart.
So… Most electronics you have to keep the vents clean to make sure you don't let the smoke out. This one you have to keep it clean so that it CAN let the smoke IN.
