DVK Gas Monitors for Boats

DVK Monitors have been protecting boats from the dangers of explosive gas for many, many years.

Boat On Fire

The DVK GA286 and GA286SV are GAS/FUME alarms capable of detecting the presence of inflammable gases or vapours in concentrations below the explosive limits.

The T.G.S 813/C sensor used responds to the presence of LPG (Propane/Butane), Natural gas (Methane) and Town gas including petrol fumes with calibration range of 1% to 25% LEL Propane at 20ºC.

Our DVK Monitors WA GA286SV units come with a 12 Volt solenoid and a 4m sensor lead.

They conform to the standard AS/NZS 2013 5601-2 Gas installations for LP gas installations in boats.

These units are not only a requirement but an essential safety requirement, with LPG dropping to the lowest point in unventilated parts of vessels.

Appendix E: COMBUSTIBLE GAS DETECTION SYSTEMS FOR BOATS

E2 GAS DETECTION SYSTEM

Have at least two outlets for connection of external equipment (e.g., gas solenoid valve, audible alarm, bilge blower etc.

Activate the alarm function and cause a solenoid valve to close off the gas supply whenever the concentration of LP Gas in air exceeds 25% of the lower explosive limit.

Have a latching system that continues to indicate an alarm condition until cancelled

Boat fitted with DVK Monitor

Be self-checking and indicate both normal and fault condition
