The MB-2 adds automatic bilge blower control. The blower is automatically started when a fume level of 16 to 20% LEL (lower explosive limit) is reached and remains on until fume level is safely lowered. A 30 amp relay is standard. The MB-2 system also includes a test button at the display module to activate the warning lamp, alarm horn and blower motor.
