Aico Ei428 230V Mains Powered Relay Module

The Aico Ei428 is a 230V mains-powered RadioLINK relay module. When the alarms in the property activate, it switches volt-free contacts to trigger external devices such as a strobe light or telecare system. It receives the alarm signal wirelessly using Aico RadioLINK, so no cabling is needed between the module and the alarms.

It works with the Aico 140RC (on an Ei168RC RadioLINK base), 160e (with an Ei100MRF RadioLINK+ module), 3000 Series (with an Ei3000MRF SmartLINK module) and RadioLINK carbon monoxide alarms. It can be set up to give a 230V output, or a 24V output using an external 24V supply. Built-in rechargeable lithium cells keep the relay working during a mains failure.
