EI428 Radiolink Relay Module
In stock
Product Code
U81672
The Ei428 Relay switches upon receipt of an alarm signal from a compatible Ei devices. The electrically isolated contacts can be used for many applications such as signaling, turning on lights, strobes etc.
It is powered by 230VAC mains and has a rechargeable battery backup. The battery backup provides power supply for up to 2 months in case of mains failure.
The Ei428 relay is primarily designed to work with RF devices, but for additional flexibility it can also be used with hard wired interconnect systems.
It uses advanced radio transceiver technology with unique software coding to transmit and receive the RadioLINK RF protocol. This ensures a robust “mesh” of RF signals and reliable paths of communication. The house coding feature confines the RF communication to designated devices only, thereby avoiding the inadvertent activation of neighbouring alarm RF systems.
As supplied the relay operates continuously but can be easily adjusted to pulse condition. In continuous mode, the relay switches until it receives an alarm cancel signal. In pulse mode, the relay switches for 5 seconds only.
The Ei428 has built in circuitry to aid suppression of voltage transients and RF interference.
Unlike a smoke detector, the relay does not need to detect smoke and is therefore quite flexible in terms of positioning. However, it is convenient to place it near the device it is controlling as well as its power supply.
