Aico Ei1428 Mains Relay Module Base RadioLink

Aico Ei428 RadioLINK Relay Module — Mains-Powered Wireless Relay For External Devices.

The Aico Ei428 RadioLINK Relay Module provides a simple way to link your Aico wireless alarm system to external devices such as strobes, sounders, telecare units or door controls. When any interconnected alarm in the system activates, the Ei428 switches its volt-free relay contacts so third-party equipment is triggered automatically.

Seamless Integration With External Equipment

Designed for use in domestic and light commercial installations, the Ei428 allows you to pass fire or alarm signals to ancillary devices without running extra control wiring around the property. The volt-free relay contacts, rated at 5A, make it suitable for a wide range of interfaces including beacons, panel inputs and call systems, helping you tailor the alarm response to occupants’ needs.

Installer-Friendly Design

The module is mains powered for convenience and incorporates a rechargeable lithium back-up battery, so it continues to operate during short power cuts. Front-facing LED indicators clearly show power status plus RF transmission/low battery, allowing quick fault finding during commissioning and maintenance. Its compact enclosure and straightforward wiring keep installation time to a minimum.

Reliable RadioLINK Performance

Using proven RadioLINK wireless interconnection at 868.499MHz, the Ei428 offers an open-air RF range of over 100m, helping alarm signals reach reliably across larger homes, HMOs and supported-living schemes. Low power consumption of just 0.8W and a 5-year manufacturer warranty make it a robust, low-maintenance choice for long-term life safety systems.
