Both smoke/carbon monooxide detectors are hard wired and have battery backup- one started beeping every 30 seconds the night before last and the other one started last night. We have replaced the batteries to no avail. The units are 7 years old, does this mean they both have to be replaced?. Or any other suggestions?
