Product Information

Product Description
The Ei428 Relay Base is a device that switches a relay upon receipt of an alarm signal from a suitable Ei alarm. The electrically isolated contacts can be used for many applications such as signaling, 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). As supplied the relay operates continuously but can be easily adjusted to pulse condition.

The Ei428 relay base is primarily designed to work with the other range of RadioLINK products, but for additional flexibility the Ei428 can also be used with conventional hard wired interconnect systems.

The Ei428 uses advanced radio transceiver technology with unique software coding to transmit and receive the radio signals. The transmissions are frequency modulated (FM) and use Manchester coding to ensure robust signal integrity and avoid signal noise interference

The Ei428 has built in circuitry to aid suppression of voltage transients and RF interference.
