Ei Electronics Ei600MRF Alarm Expansion Module RF

The Ei600MRF is an optional RadioLINK+ add-on RF module for the Ei650-compatible alarm series. Designed to plug into the dedicated slot in the base of the alarm head, the module confirms correct installation when its LEDs flash. It operates at 868 MHz with a transmission range up to 100 m, is powered by an internal lithium battery and has a compact housing (60 mm x 30 mm x 20 mm). The Ei600MRF enables reliable wireless communication and extends the functionality of compatible Ei alarm systems.

Advantages

The Ei600MRF creates a mesh-style RadioLINK network using a TI transceiver to transmit, receive and repeat RF signals, which improves signal robustness and communication paths. A house coding feature restricts communication to designated RadioLINK devices to prevent interference with neighbouring systems. The module supports up to 12 RadioLINK devices and includes remote learn functionality that allows the installer to set or re-activate house coding from a single device.

Suitable for

• Expanding wireless connectivity of Ei650-compatible alarms
• Creating a multi-device RadioLINK mesh network (up to 12 devices)
• Retrofit installations where a compact RF module is required
