DKM502
37.5kHz – 30 Day Marine Beacon
With Over 50+ years of crafting experience of underwater acoustic beacons the DKM502 is the acoustic locating beacons for maritime VDR & other application. DKM502 will assist in location of VDR & S-VDR capsules up to 6096 meters or 20,000 ft. depth underwater at sea.
The DKM502 will provide a minimum of 30 days of uninterrupted operation once activated, complying with Minimum standard specification SAE8045, IEC61996-1 & IEC-61996-2.
Physical Characteristics
- Watertight aluminum case (1.3”dia, 3.92” length (less mount)).
- Capable of operation at depths of up to 20,000 feet (6096 m)
- Detectable at a range of 2000 to 4000yards (1800 to 3600 meters) based on environmental factors.
- Sustained pressure up to 8700 psi.
- Dual water switch actuation initiates beacon operation upon immersion in either fresh or salt water.
- The battery used to power the DKM502 will sustain beacon operation for a minimum of 30 days at an acoustic output of 160 dB operating frequency is37.5 kHz.
Standard Features
- Corrosion resistant hardware and epoxy.
- Chemical coating systems MIL-A-8625F.
- The beacon will operate for a minimum of 30 days after being immersed in the water. The beacon will withstand depths to 20,000 feet (6096 meters). It can be detected at a range of 2000 to 4000 yards (1800 to 3600 meters) with DSL-375 series of Locator.
- ATS-270M Portable Test Set shall be used to perform operational tests on the beacon.
