## Summary description

The Ei200MRF is an RF add-on module from Ei Electronics operating at 868.5 MHz. It features a transmission range of up to 100 meters and is powered by a lithium battery. Compact in size with dimensions of 60mm x 30mm x 20mm, this green module is designed for easy integration into existing alarm systems, enhancing their functionality and reliability.

## Long description

The Ei200MRF is an add-on RadioLINK+ RF module for compatible Ei208-series CO alarms. The compact module plugs into the designated slot at the base of the alarm head and the LEDs indicate correct fitting. Operating at 868.5 MHz and powered by a lithium battery, the Ei200MRF extends alarm functionality by enabling wireless interconnection between devices and improving system reliability.
Advantages
The Ei200MRF supports wireless interconnection of up to 12 RadioLINK devices, forming a mesh network that transmits, receives and repeats the RadioLINK RF protocol for robust signal paths. A house coding feature confines RF communication to authorised RadioLINK devices to prevent accidental activation of neighbouring alarm systems. Remote Alarm Learn allows installers to set or re‑activate system house coding from a single device, and a buddy monitoring system provides RF path monitoring so devices can report communication loss or other events.
Suitable for
Expanding Ei208-series carbon monoxide alarm systems with wireless connectivity
Homes or small buildings requiring up to 12 interconnected RadioLINK devices
Installations where mesh RF coverage and monitored signal paths improve reliability

Use the RadioLINK tool as needed to download event logs such as alarm activations, faults, tests and head removals.
Usage recommendations
Installers should verify RF coverage across the intended installation area and ensure each device forms at least one buddy link. Follow manufacturer guidance for battery replacement and safety checks; use the RadioLINK tool to confirm network health and to download event information when commissioning or servicing the system.
