About the Aico Ei428:
The Aico Ei428 RadioLINK Relay Module switches a relay upon receipt of an alarm from an Aico RadioLink fire alarm system.
The electrically isolated contacts can be used for many applications such as linking into a nurse call system, signalling, turning on lights, strobes etc. The Ei428 Relay Base is powered by 230VAC mains and has rechargeable battery backup cells (in the event of a mains failure).
The Ei428 is designed to operate with all Aico (Ei) RadioLINK products.
