Report Replace unit on smoke alarm Ei141 in Smoke Alarms Posted June 18, 2019 Hi I am replacing the battery on an Ionisation smoke alarm model Ei141 as it is beeping. I notice the cover says "replace by Sep 2020". Does that mean the unit or just the battery? I cannot see anything in the manual which explains this. Thanks.
