Guest Phil Woods Posted January 30, 2021 Report Share Posted January 30, 2021 I'm replacing my EI151 with EI141 but the 141 has it's own replaceable battery rather than a built in rechargeable one. So what do I do with the blue battery wire I have from the old 151? Quote Link to comment Share on other sites More sharing options...
Guest Posted February 1, 2021 Report Share Posted February 1, 2021 Hi Phil The 150 and 140 series alarms have different bases, hence the need for rewiring. We always recommend that such work is undertaken by an electrician or other qualified, competent person due to the dangers involved with mains electricity and the need to ensure the alarms are powered as necessary after installation. Assuming your system was installed with wiring coloured according to accepted standards, you should find two blue wires - one neutral wire from your electrical installation which must be connected to the new base for the Ei141, and a short length looped from and back into the old Ei151 plug. This short length is used to disconnect the lithium battery when the plug is removed and can be discarded as it is no longer necessary for your new alarm.
