MX920 Product Description:


The Qolsys DSC MX920 is an MX digital loop line isolator module designed to be used on MX addressable controller loop circuits. It connects to the MX addressable loop circuit of the HSM3105. The MX920 module is used to monitor for short circuits. If it detects a short circuit, it will isolate the affected section while allowing the rest of the addressable circuit to function normally. This module ensures that a single short does not disable the entire MX addressable loop circuit.

Product Features:

  • Short circuit detection insulating the affected section
  • Designed to be mounted in a standard dual-gang MK box
  • Yellow LED to provide indication of unit operation

Note: This equipment must be installed by a skilled person only. A skilled person is an installer with appropriate technical training. The installer must be aware of potential hazards during installation and measures available to minimize risks to the installer and other people.
