What to do if Vigilant MX1-Au Button LED flashes but does not change state?

If the button LED flashes but does not change state, it means communication between the DSS master and the MX1 main board or network communications with the remote DSS controls have failed. Check the communication cable from the master control board to the MX1 main board. Check the network communications if the control is a ‘Duplicate’.
