Aico Ei128RBU Mains Relay Module with Battery Back-Up

The Aico Ei128RBU is a hard-wired relay module with rechargeable lithium battery back-up. When any interconnected Aico alarm sounds, its relay contacts switch to signal an external device such as a fire panel, warden call or nurse call system.

It is for use with Aico 3000, 2110e, 160e and 140RC Series alarms, and 260RC Series CO alarms when using the Ei128COV cover. It fits discreetly behind a smoke or heat alarm, or can be sited remotely with the supplied cover. The lithium cells give up to 2 months of operation without mains power.
