DKM502
37.5kHz – 90 Day Marine Beacon
Building on over 50 years of underwater acoustic beacon manufacturing experience, Dukane Seacom has developed DKM502/90, which is the newest version of the IMO standard in underwater acoustic locating beacons for maritime use. Expanding on the proven reliability of the DKM502, the DKM502/90 will assist in locating VDR and S-VDR capsules at up to 6096 meters or 20,000 feet water depth.
The DKM502/90 will provide a minimum of 90 days of uninterrupted operation once activated, complying with minimum standard specifications SAE8045A, IEC61996-1 and IEC61996-2. BSH approved.
Physical Characteristics
- Watertight aluminum case (1.3" diameter, 3.99" length, excluding mount).
- Capable of operation at depths of up to 20,000 feet (6096 meters).
- Detectable at a range of 2000 to 4000 yards (1800 to 3600 meters), depending 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 DKM502/90 will sustain beacon operation for a minimum of 90 days at an acoustic output of 160 dB. Operating frequency is 37.5 kHz.
Standard Features
- Military-grade corrosion protection.
- Chemical coating systems MIL-A-8625.
- Innovative engineering technology that protects against inadvertent actuations.
- ATS-270M Portable Test Set shall be used to perform operational tests on the beacon.
- It can be detected at a range of 2000 to 4000 yards with a DSL-375 locator.
