What is the maximum wiring distance between an MX power module and its furthest MX flasher module?

This article discusses the maximum radius between the power module and its furthest flasher module.

Product applicability

The following products are discussed in this article:

  • MX Series: R920-MX, R829-MX, R247-MX, CHEVRON-MX and WWD-MX

When wiring your MX system in a "distributed approach" you will need to follow the guidelines outlined below for maximum distance between the power module and last flasher module, based on the number of flasher modules and type for your application. For example:

  • 1 power module with six 12" yellow round beacons —> 35 feet of wiring maximum from power module to last beacon.
  • 1 power module with eight RRFBs —> 30 feet of wiring maximum from power module to last RRFB.

The distance of wiring is calculated based on wiring used from the power module through each flasher module.

Below are the options if you plan to use the distributed wiring approach with several flasher modules on a single power module:

  1. Limit the number of flasher modules to five per power module, or whatever number is required to stay within the limits as per the table below.
  2. Increase the wire gauge for the flasher module wiring to 16 or 14 AWG.



If you experience overcurrent faults or flashers not working it may be due to running too many beacons and exceeding the wiring distances as per the table above.
