K5431R /  D 451 FU-EBI PF o.T. 1 Gang Volt Free Multi Function Switch Receiver
The Echo K5431R 1 Gang Volt Free Multi Function Switch Receiver offers great versatility by virtue of the potential free floating switch contacts. Isolation from the mains supply enables the freedom to control almost any device with both AC and DC voltages. The receiver can be assigned to a maximum of 32 Echo switch transmitters, the function of each switch being individually programmable. Each transmitter can control an unlimited number of receivers. The receiver is designed to be installed into a flush mounted installation box.

Applications include converting existing wired controls to Echo radio control and updating existing remote controls to Echo EnOcean technology.

Selectable functions: pushbutton
• Staircase style lighting with selectable switch OFF delay and advance OFF warning

The range between the transmitter and receiver (or repeater) in a typical house is about 30m (line-of-sight) and 100m in open spaces. The actual transmission range depends on the materials used in the building and nearby interference sources (See the product install guide). Range can be increased by the use of the repeater function available in this receiver or the stand alone Echo K5440R Repeater.
