I am looking for smoke detectors that do NOT beep when the backup battery gets weak.
My system is house 115v powered/backup battery that is connected to each other.
The beep when the battery gets low terrifies my dog and is useless since I can't hear it anyways.

Anybody know of a brand without the beep?

Everything I saw referenced the battery as a backup in case a 115v-wired system loses power, but (Google) Nest Protect has an ring LED indicator for visual reference per device to show it checked itself & all is well.

We're on a similar 115v system & I had to run out in the middle of the night recently to get a 10' ladder to replace a battery that was low & terrorizing our cat. (Vaulted ceiling)

I'm not certain what you're looking for exists, although the LED device described above is intriguing.

There are smoke detectors out now that the battery supposedly lasts for 10 years. They're more expensive but you (hopefully) wouldn't have to listen to the beeping for a long time.

If you contact the manufacturer direct, they might sell at a better price.

I once was in a housing project apartment where the person was deaf and they had the smoke detector wired to a flashing lightbulb...

Had the doorbell wired to a different colored bulb.

Identifying and disabling the beeper on the detector's PCB should be trivial, desoldering/removing it a little more of a challenge, but not too hard, I'd think. I don't know how that might affect an insurance claim in the event of a fire, or liability for injury/loss of life, but if it bothers the dog...

It's a safety feature, you can't buy it. It would be like trying to buy a car without air bags or ABS. Best bet is to buy the ten year sealed lithium ion batteries or just remember to change your batteries every year. Many people find it easy to do by picking a day like Christmas or New years day. Electronic calendars you can also set up reminders far, far into the future.

This really is rather an annoying pain, especially if you don't happen to have spare batteries in the house.

Does the beeping continue if you remove the battery?

Since houses now have 30 of these detectors, it would be nice if they were all wired to a single battery like the one used for home burglar alarms. Then just replace one battery every few years or so.

Don’t buy the ten year battery only units that just have a battery and that don’t use the house 120v wiring. They are advertised to last ten years and everyone of them I installed lasted two years until they started beeping and in need of replacement.

You may have power quality issues. 80%+ they are fine. People when get surges/outages don't fair so we'll. Also the ones made before 2018 were the worst. I personally would never buy them because the old school ones work just fine and if you don't have power outages the batteries will last 4-5 years (or until you have long outage).

OK if its beeping just pull the unit and that's the end of that. I have not had the bad experience on the 10y units, but since you already have 120v units, that's a step backward. Just change the batteries on a decent schedule and problem solved. Its not hard.

You can put lithum AA batteries in if you dont want to hop up the ladder every year. I did that on one of mine that is way up there, like 14-16 feet up as its hard to get to.

I replace all of my other batteries every year on schedule, but the really high one has been fine for a couple years on a Energizer advanced lithium battery.

The battery is only used in a power outage, if you have reliable power, they will last 4-5 years+. I haven't changed mine in 7 years, probably time to do so, but I don't lose power for more than a few hours once or twice a year.
