The BREAKSAFE RM6000 Remote Battery Monitor is fitted in the tow vehicle and operates each time the brake pedal is pressed. The additional circuitry in the BREAKSAFE 5000 and 6000 disconnects the Breaksafe battery from the charge circuit and then connects it to a small electronic load. Should the Breaksafe battery be fully charged, a green light will illuminate on the front panel of the RM6000 Remote Monitor. If the battery is below the safe level, a red light will flash and a buzzer will sound for about 10 seconds.
Note that a remote battery monitor is required by the NSW RTA to be fitted to the tow vehicle.
