Electronic vacuum alarm system

Nauticam is pleased to announce an exceptionally comprehensive vacuum system that allows the underwater photographer to confirm watertight integrity before entering the water. This system provides additional peace of mind with expensive camera equipment and should mean fewer dives lost due to minor equipment problems. The system consists of two parts, a one-way vacuum valve and an electronic monitoring circuit.

Monitoring circuit

The electronic monitoring circuit is compactly integrated into the housing's leak detector, where it constantly measures the vacuum level and reports its status via an easily visible multi-color LED on the back of the housing. This sophisticated circuit has advanced temperature compensation capability, so changes in ambient temperature or changes in internal temperature will not cause a false positive.

Beginning with NA-70D for Canon 70D, all new Nauticam mirrorless and DSLR interchangeable lens camera housing models will be shipped with electronic monitoring circuitry installed as standard equipment. Vacuum valves are sold as optional equipment, allowing the user to customize the housing accessory configuration as needed. Understanding the LED color codes is very easy. At ambient pressure, the LED slowly flashes blue. When a solid vacuum is achieved, the LED changes to solid green, indicating system integrity. If the vacuum begins to degrade, the LED starts flashing yellow, and if water intrusion is detected, the LED flashes red and the audible alarm sounds.

Vacuum valve

The second component of this system is a one-way vacuum valve, which is available in several styles to support various housing configurations. These vacuum valves contain an integrated vacuum release and a redundant watertight lid. No tools are required to open the housing after creating a vacuum, as the vacuum is released with a simple knurled nut.

The basic valve uses a hand pump to create the vacuum, but a more advanced dual-activation vacuum valve is also available. The dual activation valve accepts a quick disconnect from the BCD low pressure inflator hose and uses the tank pressure to create a Venturi effect that pulls the vacuum. This is recommended for housings such as Nauticam's DCES for RED EPIC and SCARLET, where the internal volume of the housing makes the use of a hand pump impractical.

"Offset" extension valves are used when a casing has only one accessory port, but requires that both a vacuum valve and an electrical bulkhead be installed in the same location. This will allow most casings to utilize this valuable tool.

All vacuum valves also include a hand pump and valve installation wrench.

Bottom line

This new system is the most advanced integrity verification system available today and the only one with built-in leak detection and temperature compensation. With its intuitive multi-color LED status codes, the underwater photographer can now be assured at a glance that the watertight integrity of the housing is secure.
