  • Low-battery warning chirp and missing battery tab alert you when unit requires a new power source

three short beeps

what does three short beeps that happen infrequently mean? an model 7010B this has been happening since I installed it over a year ago.
Asked by: denn
Just talked with Mfgr. 3 short beeps every 60 seconds is a "malfunction". Nice that the owner's manual doesn't tell you what that is though.... Called the Mfg., and am told that our units manufactured in 2010, are past their 5 year live by 12 months. the Three beeps tell you they are still working but time to replace. When it gets to 5 beeps, the alarm is no longer functional, just keeps beeping to tell you that. Same model number manufactured now, has a 10 year life.

Where should these detectors be installed?

I thought CO detectors were supposed to be installed low on the wall and smoke detectors high. Also, they used to say CO detectors should be installed near potential sources of CO, like a gas furnace or water heater. I am thinking I will install one of these in the hall near our furnace and 9120B smoke detectors in all of the bedrooms. Since they are interconnected, there should be enough noise to wake us in case of excessive CO. I know that's not what they say in the manual but they are trying to sell as many devices as possible!
Asked by: eegorr
The experts recommend 1 unit per every level of your home. In bedrooms or directly outside of all bedrooms. Most homeowners typically have 1 unit mounted on the ceiling outside of the bedrooms.

Hardwired Interconnected Smoke and CO Alarm with Battery Backup is rated 4.4 out of 5 by 223.

I bought new house that came with 3 of these detectors. the first one was malfunction after 4.2 years (from the date in the back of unit) and I ordered a replacement through Home Depot. The second one started 3 beeps/min as malfunction recently (so ~4.5 yrs). This time I called the First Alert customer service for warranty, as advised from someone else. Surprisingly, the customer service was quite really great (which is the reason i give 4 star review) and they ordered a replacement for me. The third one has yet made any beep as malfunction as the others. and so far I am seeing that the life of this detector is somewhere from 4 years and up (warranty for 7 years).
