The WS4920HE - DSC Wireless Repeater Module is a wireless repeater designed to extend the range of DSC one-way wireless transmitters and to improve signal quality between the transmitter and receiver. Use the WS4920HE to remedy transmission problems caused by excessive noise or other interference, or by long distances between devices and receivers. The maximum recommended number of WS4920HE's per alarm system is 4.

Each enrolled WS4920HE occupies a zone slot. The WS4920HE does not increase the number of supported wireless zones. This is determined by the control panel's wireless receiver. Only zones requiring repeat functionality need to be enrolled on the WS4920HE. Ensure these zones are enrolled on both the WS4920HE and the receiver/control panel.


  • Greatly extends the range of DSC 1-way wireless devices
  • Backward compatible with existing security systems including ALEXOR, PowerSeries and MAXSYS
  • Identifies the optimal location for mounting - taking in to consideration noise and interference
  • Quick enrolment of DSC 1-way wireless devices
  • Status LEDs for AC, battery and RF Jam
  • Up to four repeaters can be supported per system
  • Supports up to 164 wireless devices
  • Wall and case tamper protection
  • Esthetically pleasing design

Installed my own system and had recurring faults with a couple of zones that were pretty far from the panel. After I installed the repeater, the fault issue went away. Now I just wish I had installed it earlier.
