MMC's sonic alarm systems for bilges provide an effective means for monitoring HIGH, OVERFLOW and LOW liquid levels. Engineered for dependability and low maintenance, the system's sensor has no moving parts to become jammed with bilge debris.

An intrinsically safe version of the alarm system includes a safety barrier.

Audible and visual alarms provide immediate indications of critical conditions.

The standard version utilizes 115 V (AC), 60HZ, 1ø phase power. A 220 V (AC) power option is available with a separately purchased step down transducer.
