There are 11 smoke detectors in my house. I just replaced them all with ac units with lithium battery back-up.
Unfortunately, when one goes off they all sound off at the same time, sending our critters for their favorite hiding place and driving my wife out of the house. The sound is deafening as there's no car pen in the house to absorb sound. It really is painful.
I did a web search for "smoke detectors without alarms" and Google responded, "Did you want smoke detectors with alarms?"
I know there are people here that have one in every room, required by many localities. WTF do you do when they all go off?
