This MANUAL contains the de-scription, theory, installation and maintenance forthe DK100/DK120/DK130/DK140 UnderwaterAcoustic BEACON , hereafter referred to as the DKSeries , manufactured by Dukane Corporation,Seacom Division, 2900 Dukane Drive, St. Charles,Illinois, 60174. These beacons have been tested to,and meet, or exceed, all requirements of FAA 1.

4 DK Series UnderwaterAcoustic BEACON Installed inMounting SYMBOLS AND and abbreviations used in this MANUAL arein accordance with ANSI and MIL-STD-12, GENERAL PHYSICAL CHARACTERISTICS. TheDK Series beacons consist of a self-containedbattery, an electronic module and a transducer. Itis housed in a cylindrical watertight aluminumcase capable of withstanding high-G impactshock and deep-water immersion. As shown onpage 6 and 7, the DK Series beacons operate for30 days when immersed in water. See Figure 2. Water Switch Locationon BEACON MOUNTING. The BEACON ismounted to a flight recorder or the airframe bymeans of a mounting kit (See Section II). Thismount consists of an extruded channel, which inconjunction with a securing plate retains the bea-con.

5 Figure 1 shows the BEACON mounted in theN30A21A Mounting Kit, a strap-type mount. Thismount is used for applications where space limita-tions do not permit the use of the simpler N30A26 Series cradle BEACON SIGNAL. The BEACON is a bat-tery-powered device, which radiates a pulsedacoustic signal into the surrounding water uponactivation by its water-sensitive switch. Searchoperations in water for BEACON equipped aircraftcan be conducted by utilizing a portable receiverequipped with a directional hydrophone such asthe Dukane Model N30A5 Series Locator receiver system is operable from small boats orby free-swimming lost in deepwater, , in excess of 6000 feet (1829 meters), re-quire special search gear.

The aft mid-section of theaircraft is normally the most desirable locationfor the BEACON , but consideration must be givento environmental conditions outlined in The area selected for the BEACON mountingshould be free of the possibility of heavy equip-ment tearing loose and striking the Installation should be made to a substan-tial structural member, but kept as simple aspossible and must not weaken the The DK Series BEACON must not be disas-sembled, crushed, penetrated, incinerated orexposed to temperatures above 160 F (71 C).

8 The BEACON is a battery-powered deviceand installed shelf life is affected by higher thannormal temperatures. Maximum temperaturemust not exceed 160 F (71 C). Inadvertent actuation of the water switch byany source of water, such as rain, salt spray, meltingice or snow, head or washroom overflow, foods andbeverages, must be In order to avoid accumulation of moistureon the water-switch, the device should bemounted with the long axis of the BEACON hori-zontal or with the water-switch facing down. Aclean switch will allow moisture to collect intodroplets and run off the switch, without activat-ing the Honeycomb structure, tarpaulin fabrics,clothing, parachutes, cargo, etc., are sound-absorbing materials. Do not surround the devicewith these materials and if necessary, removesmall areas of such materials from the Any compartment that may not be ex-pected to flood under light impact should not beused.

9 Direct contact between the BEACON case andwater is necessary for actuation and addition to observance of the precedingmandatory considerations, where possible theselection of a mounting location should providefor convenient BEACON access during inspectionintervals. The proper mounting location shouldalso provide for clearance for removing thebeacon from its mounting REV 16 Page 9 of INSTALLATION PROCEDURES FORTHE DK100/DK120 AND THE N30A26 SERIES MOUNTING GENERAL. Model N30A26 Series Mount-ing Kit (Cradle Type) is an aluminum extrusion witha screw-attached securing plate that providesrugged mounting and protection of the BEACON withinthe aircraft. See Figure 3. The BEACON should bemounted horizontally with the switch end forward, ifpossible. If vertical mounting is necessary, switchend must bemounted downward to prevent accu-mulation of dirt, grease and water on the switch CRADLE MOUNTING Using Figure 3 as a guide, locate the inch ( cm) diameter holes on inch ( by cm) centers.

10 Be sureaccess to the securing plate end is available forfuture BEACON installation and removal. Approxi-mately inches ( cm) clearance should beallowed for BEACON 3.
