Extend & Strengthen UPB Communications Reliability

Enhanced over the original model, this PCS PulseWorx UPB Wired-In Split Phase Repeater, re-released in 2016, offers a simpler installation process to help you extend and amplify UPB communications more easily than ever. Designed for use in a home with a 120V/240V split-phase electrical system, the Split Phase Repeater works by repeating UPB commands transmitted on one phase (leg) of the electrical system onto the other phase (leg), and amplifying them by 150 percent. This allows UPB devices to communicate no matter where they are in your home.

This Repeater installs in a junction box and wires into two phases (circuits), as well as the neutral of the circuit breaker panel. This upgraded model features four main improvements over the original model:

  • Same size as wall switch models RWS, WS1DL-6, WS1R-15 to match
  • Fits in a single-gang box just like a wall switch dimmer
  • No longer requires junction box knockout
  • Offers convenient mounting points for secure installation

Configuration Details

Like all PulseWorx devices, the Split Phase Repeater can be initially configured using PCS's free UPStart Setup Software tool. UPStart enables configuring such parameters as Network Name, Network ID, Unit ID, Room name, Device name, default on light levels, fade rates, LED colors, dimming disable, auto shut-off time, etc. as well as test the operation and communication strength of the device. UPStart has the option to configure an entire network offline and then download the information into the devices after they are installed in the home.

UPB PulseWorx Lighting Control System

An integral part of a complete PulseWorx Lighting Control System, this device uses the patented UPB powerline communication technology (invented by PCS) to reliably communicate with any other UPB-compatible devices over the existing house electrical wires. No new wires are necessary, thus making PulseWorx perfect for retrofit situations. When initial configuration is complete, a single push of a button is all you need to activate any group of lights (or virtually anything else that connects to AC power wiring) throughout the house simultaneously.
