The Ei128RBU is a Relay Module that runs on a 230V AC mains power and has built-in tamper proof Lithium cells that act as a battery back up in the event of mains failure. These rechargeable lithium cells are designed to have a 10-year life and outlast the life of the module itself, whilst providing up to 2 months of operation without mains power.
For use with 3000, 2110e, 160e and 140RC Series alarms (and 260RC Series Carbon Monoxide alarms when using the Ei128COV cover).
