Guest Mol1 Posted February 17, 2022 Report Share Posted February 17, 2022 I have previously installed interlinked smoke alarms in 2005 (not wireless) i now need to add a heat alarm to comply with regulations can I do this with my existing set up or do I have to change all my alarms to wireless? Thanks Quote Link to comment Share on other sites More sharing options...
green-foam Posted February 21, 2022 Report Share Posted February 21, 2022 If you installed wired smoke alarms in 2005 You should change ALL of them as they only have a 10 year life. If it is easy to install a new 3 core and earth cable from one detector to your new Heat alarm, then I would do that as it will be cheaper than all new radio alarms, but if it is not easy then yes, change them all to radio interlinked alarms.
