February 15, 20224 yr comment_24031 Hi . I have no green lights on 3 of my detectors that are hard wired, But when I test them they all sound as they are meant to with the battery back up .. I have switched them round with other detectors on a different circuit and the green light shows . Model AicoiE141 Whats the likely problem ,? Report
