Customer Reviews

Battery Operated Photoelectric Smoke Alarm with Escape Light is rated 3.8 out of 5 by 4.
Rated 5 out of 5 by from I'm so impressed! I'm so impressed with the product. It's not flimsy! In fact the price I think it's reasonable, I've actually seen it work and I would definitely buy more when the time comes. I recommend it because it's not just a smoke detector it's also an electrical detector. This is actually with the fire marshals recommend that homes have instead of just smoke detectors I did my research.

Rated 3 out of 5 by from Works okay for a couple of years We got this smoke detector about 2 years ago. It works the same as any other detector (alarm goes off while we are cooking). However, it malfunctioned today and will have to be replaced. It started beeping as if the battery was low, but I have replaced the battery with 4 other batteries (3 brand new from different packages and manufacturers, and one from another smoke detector in the house that is functioning fine) and it continues to make the same beep. The little red light flashes, as if it is working properly, but when I try to test it, neither the alarm or escape light will work and then the red light stays on. There is no dust build up. I even wiped off the metal prongs to make sure there was nothing preventing a good connection with the battery. This replaced a 20 year old detector that still worked fine, I just wanted one with an escape light. Very disappointed to have it malfunction after 2 years.

Rated 3 out of 5 by from closest I could find for hearing impaired was looking for a battery powered photoelectric smoke detector with strobe for hearing impaired tenant, but couldn't find after web search-this only has a small light that turns on with the alarm, but doesn't flash; we'll see if useful/effective
