Small, but really loud. They work really well.

I was kind of nervous when I saw the size of box that two of these came in, but when my husband hooked them up and tested them and we heard the sound they put off we realized that size does not matter. It is loud enough for us to hear from far away. We have one at one towards our room and one by the kids' room. I'm very happy with this purchase. We replaced our much older, much bigger ones for these. I couldn't be happier, plus they come with batteries. What else could you ask for.

Reliable brand

I wanted UL listed reliably designed alarms for my workshop and garage. I installed these on new years so it will be easy to remember to replace the two cheap AA cells each year as a routine. Low battery chirping in those locations will not be too bothersome. The mounting plates are easy to install. In some cases the power goes out (Blown circuit breaker caused by a shorting appliance) before the alarm can sound so AC detectors are of limited value. Lithium batteries last much longer but they also cost much more and I recycle all of my used batteries anyways. I tested these with cigarette smoke and they responded fast. Keep in mind that 10 year old detectors should always be replaced. I have no fire insurance and 5 smoke detectors as well as 4 extinguishers and three fire blankets.

Gary, we understand how frustrating continued chirping can be, especially after only two months and after you’ve already replaced the batteries. Different chirp patterns can indicate different alarm conditions, so our Product Support team can help identify what your alarm is communicating and determine the appropriate next steps. Please call 1-800-880-6788 with your alarm available so our team can help troubleshoot.
