Sonihull Sonihull Quad
A 4-output control unit with a fault relay output for remote monitoring
Features
Features
Dry-side installation
Transducers are bonded with epoxy to the dry side of the hull, sea chests, coolers or pipework, with no through-hull penetrations.
Suitable materials
Suitable for materials that transmit ultrasound well, including FRP, GRP, aluminium, steel, stainless steel, titanium and rigid plastics; professional installation is recommended for FRP/GRP sandwich construction; not suitable for wooden hulls.
Monitoring and fault output
Run timer for healthy operating hours; monitoring of the 4 transducer outputs can be disabled individually (transducer output is unaffected); a fault relay output (24 V DC, 400 mA) supports remote monitoring and also signals a fault when power is lost.
Low DC voltage warning
The power LED flickers when the DC supply is between 11.9 and 12.4 V; on battery-powered installations this indicates poor battery condition.
Maintenance
Under the manufacturer's maintenance schedule, the crew carries out weekly and monthly checks and renews the transducer gel every 6 months; a manufacturer service engineer services the system every 5 years or at dry-docking.

Notes
- The Quad is also known as the 04.
- The number of transducers is configured after assessing vessel type, structure and areas to be protected.
- Power consumption is measured during operation at 230 V AC.
- The AC voltage selector must be set manually to 110 V or 230 V; check the switch position before installation.
- The system prevents biofouling; it cannot remove established hard fouling, so surfaces must be cleaned before installation.
