Ei128R Mains Relay Base

The Ei128R Mains Relay Base is a reliable accessory designed to enhance the functionality of compatible fire and carbon monoxide alarm systems. This mains-powered relay module connects to interconnected alarms and activates external devices when an alarm is triggered, providing additional safety and signalling options.

When a smoke, heat, or CO alarm within the system activates, the relay module switches its contacts to trigger connected devices such as strobe lights, telecare systems, magnetic door holders, or remote sounders. This allows alarms to integrate with other building safety equipment, improving awareness and response during emergencies.

The Ei128R is powered by a 230V mains supply and connects through a hard-wired interconnect line. It can be installed directly underneath a compatible alarm base or mounted remotely using the supplied cover, offering flexible installation options for residential or commercial properties.
