What type of smoke detector is in this unit....ionization or photoelectric?

Asked by: ALinNC
CAUTION: MASSACHUSETTS requires a photoelectric alarm in all residential situations. This ionization device has limited use in MA and in the few situations where it could be installed, it would need a photoelectric alarm mounted next to it.

can the battery be changed??

after ten years
Asked by: john
Not without breaking open the unit and voiding the warranty. Sealed unit is not designed for user battery replacement. Battery life > 10 years and built-in warranty timer means you should never have to replace the battery for the useful warranted life of the unit (10 years).

I have a 2 story colonial which is hardwired with regular smoke dectectors on all levels. One in basement, one on main floor and one in each room

upstairs as well as the hallway upstairs. How many smoke and co detectors are necessary in this design? And can the Kidde worry free be installed where I now have BRK Electronics model 4120B?
Asked by: bigJim

However, the store stocking/restocking process needs a lot of work. After two trips to the store for a missing part (electrical pigtail connection) on the third trip I had to open five boxes to find one that had the missing part.

The idea of no battery replacement is very attractive. I have had problems with tenants replacing the batteries on earlier Kidde products and ruining the detector in the process. This model eliminates this problem. Nice that that this detector gives a warning when it is time for replacement. Great improvement.

Remaining two had low battery warnings immediately upon installation even though they were from the same unopened case lot as the others. Home Depot replaced the defective units; and there were no further issues. With the exception of the quality control issues (minus one star), the units are performing as designed.

It is very nice to know I do not have to worry about the batteries for 10 years. The units I replaced needed new batteries every 2 years and always seemed to go low when we were not at home. The noise drove the dogs crazy until we got home.

My wife has already tested out the alarm a couple times,LOL. That lets me know the old one wasn't working well! I like the voice telling what type of alarm it is, and was able to silence it easily when it was a false alarm.

No one at Home Depot could explain or make sense of this? I was caused to retire all my alarms. Big hassle and simply poor design for no maginable purpose!

Installs easily and seems to test very well, time will tell on the battery life and trouble-free operation. I have the smoke-only versions now for about two years and they have been fine. No disturbances or effort needed beyond periodic testing.
