Good alarms from a trusted brand. I have 3 linked alarms to cover the house and 2 linked alarms to cover the garage/sunroom. Some of these alarms are hard to access so the long-life lithium backup battery feature is handy. Can get some false alarms (mostly due to spiders, I think). When this happens I usually find it necessary to open up the alarm body to get access to the optical sensor housing to vacuum, or blow, out the offending insect/detritus. I don't think the alarm housing is designed to be taken apart but I didn't find it too difficult.

Bought this to replace a faulty one after 8 years use. The old one would alarm for no good reason. So far so good with this one. I have three of these in operation.
