make sure one of them is not is some weird mode, or has a communication issue with another. use the led flashs listed in the manual below.

Hardwired Smoke & Carbon Monoxide Detector | Kidde

This Hardwired Smoke & Carbon Monoxide Detector, Interconnectable with AA Battery Backup, model 900-CUAR, helps protect you and your family from two hazards – fire and dangerous carbon monoxide (CO) – in one unit.

we find this problem somewhat frequently after a homeowner or similar replaces them because there is a bad connection somewhere and they behave in odd ways. usually can diagnose by looking at the led flashes and testing.

Like everything else, sometimes they fail. You got a dud, replace it and move on.

With photoelectric you don't need leaks or gas or CO, just something like dust that blocks the sensor. In my workshop, mine go off all the time when I'm sawing wood, if I don't put the orange shower-cap looking cover on it until the dust settles.

Otherwise they work fine and I'd buy them again, if they were still the $30 I paid at the time but now they are $52 so I'd shop around before paying that much. I have separate CO detectors, not wired together, but the hardwired w/battery BU smoke detectors are these Kidde PI2010 :

Anyway, what I'd try first is blowing them out with compressed air or an electric leaf blower or whatever. Wait. Yours "speaks", what did it say, Fire or CO or something else?

Let loose some bigger spiders to eat the little ones?

Praying Mantis or birds might work too.

Do you like the smell of peanut butter? You could mount some of those mouse sticky traps around it, so the spiders can't cross to get to the detector, or some double sided foam tape inside it, around the sensor.

Is there an LED always lit on it? Light can attract other insects, which attracts spiders.
Are there a lot of spiders there?

I've never had this happen to mine, nor have I heard about it from anyone I know IRL. Maybe it's just a one-time event that will never happen again.

Took it apart. The part where LED beams scatter had a very tiny spider in it. This caused the whole commotion. This thing was like .3 mm small.

Now, the question is how to prevent such tiny things against nesting inside a smoke detector???

You could burn the house down to kill all the spiders, lol.

I replaced all of smoke detectors about 5 years ago (after realizing they need to be swapped out after 10 years. Mine were about 13 years old)....

I got some low discharge 9 volt batteries (for applications such as smoke detectors that are hardwired into an electrical system) that are 'supposed' to last 10 years....5 years in and they are all still good...

Here are the ones I got but they are no longer available...
