LIGHTED SMOKE ALARM
Style: Smoke
WORKS AS INTENDED

Detector Accessibility
Style: Smoke
We replaced our previous detectors with new ones with strobe lights. More accessible since we are Deaf.

Exactly what I wanted, works as advertised!
Style: Smoke
This is an integrated Smoke Detector with a Strobe light that is also capable of interconnections with up to 18 other compatible alarms. It comes with multiple power adapters so if you are replacing existing AC Powered alarms you should find a suitable connector, saving you from messing with the wire nuts, etc. Don't be fooled by cheaper Strobe devices which require separate wiring to an actual Smoke detector. The Strobe is VERY Bright and is exactly what I wanted due to having hearing impaired guests visit frequently. See short video in a darkened room. Finally, I like the idea of a 10 year sealed battery, as long as it lasts close to that long. Too many people assume Smoke Detectors work forever since the test button produces an alarm. They DON'T and may not recognize a fire due to dust accumulation and effects of higher humidity levels in certain climates. ... show more

It does what it says it will do.
Style: Smoke
It does what it says and we passed the inspection for supposedly deaf person (she's not deaf). It will not blink the strobe on battery FYI. Make sure you get AC to it.
