    Nothing comes to mind


    We purchased four of these alarms last year in May 2018 and they were installed by staff of local fire station. Today 4 Feb 2019 two of them have been sounding off constantly for no apparent reason so firemen came in uninstalled faulty ones and put in replacements (a different brand) with 10 year life span - hopefully.

    No, this product has too many drawbacks.
