Capable of being interconnected with up to 24 devices. When smoke alarm sounds, they all sound.

A soft chirp from this wirless smoke detector will notify you that the batteries have become depleted, giving them up to 12 hours to be replaced.

Easily solves interconnect requirements

Great Detector!

These units have been running in my home for a couple of years now...once in a while I change the big deal. We test them regularly (in the kitchen). When one goes off they all go off...quite a racket, but would be very effective for a real fire. I often wish for a photo-electric sensor for the kitchen though.

Questions & Answers

i purchased 8, model rf-sm-ac-dc, smoke detectors. On the back it says weekly testing is required. If it is not tested weekly do they sound off until you hit the hush button? We hooked these up at our lake house and are not out there very often. They went off for no apparent reason.

The weekly testing is only a manufacturers recommendation. The units should not "sound Off" unless there is a problem such as "low Battery"

I want to replace my FIREX 4518 Smoke detectors (discontinued) with battery-operated only detectors. I need to be sure the replacement recommendation(s) will mount to the bracket that the FIREX attaches to. Can you make recommendations?

All smoke detectors should be installed with the New equipment provided in the manufactures packaging .
