DK100/DK120/DK130/DK140 Underwater Acoustic Beacon, hereafter referred to as the “DK Series”, manufactured by Dukane Corporation, Seacom Division, 2900 Dukane Drive, St. Charles, Illinois, 60174. See Figures 1 and 2. These bea- cons have been tested to, and meet, or exceed, all requirements of FAA TSO-C121.
2.1. GENERAL. This section describes the installation of the beacon mounting kits and the installation of the DK Series beacons into these mounts. 2.2. INSTALLATION CRITERIA OF THE BEACON. NOTE All installations to Cockpit Voice Record- ers and Flight Data Recorders should be in accordance with the recorder manufacturer’s approved procedures and hardware.
2.6. INSTALLATION PROCEDURES FOR THE DK100/DK120 AND THE N30A26 SERIES MOUNTING KIT. 2.6.1. GENERAL. Model N30A26 Series Mounting Kit (Cradle Type) is an aluminum extrusion with a screw-attached securing plate that provides rugged mounting and protection of the beacon within the aircraft. See Figure 3. The beacon should be mounted horizontally with the switch end forward, if possible.
20 inch-pounds torque. F. Perform the Operational Test outlined in Section IV. 2.7. INSTALLATION PROCEDURES FOR THE DK100/DK120 AND THE N30A21A MOUNTING KIT. 2.7.1. GENERAL. Space limitations sometimes require the use of the strap-type N30A21A Mounting Kit. Where a choice exists, horizontal mounting with switch forward is best.
If vertical mounting is employed, the switch end should be facing downwards to reduce the accumulation of dirt, grease, and water on the switch end. Rotate the beacon in the mount, so that the markings and beacon replacement date label can be read. Figure 6.
2.8. INSTALLATION PROCEDURES FOR THE DK130/DK140 AND THE N30A29 SERIES MOUNTING KIT. 2.8.1. GENERAL. Model N30A29 Series Mounting Kit (Cradle Type) is an aluminum extrusion with a screw-attached securing plate that provides rugged mounting and protection of the beacon within the aircraft. See Figure 9. The beacon should be mounted horizontally with the switch end forward, if possible.
B. Make sure that the beacon case and water switch, are free of grease or film. If in doubt, wipe clean with mild detergent C. Test the beacon as outlined in Section IV to insure operation prior to installation. Figure 10. Installation of N30A29 Series Mounting Kit and Beacon D.
E. Insert the ends of the retainer straps through the 0.272 inch (0.691 cm) holes in the mounting surface. When horizontal mounting is used, position beacon with switch end forward. If vertical mounting is employed, the switch end should be facing downwards to reduce the accumulation of grease and dirt on the switch end.
3.1. THEORY OF OPERATION. 3.1.1. The DK Series beacon is a battery-oper- ated underwater acoustic pulse generator that is activated when the water switch is immersed in either fresh or salt water. 3.1.2. The water switch is part of a triggering circuit, which when actuated will initiate normal pulsing of the beacon circuit.
The TS100 Portable Test Set is not compatible with the model DK130 or the DK140 Underwa- ter Acoustic Beacons. The TS200 Test Set is compatible with the DK100, DK120, DK130 and the DK140 Underwater Acoustic Beacons. 03-TM-0037 REV 13 VOLTAGE 3.55 VOLTS...
5.3.2. See Sections 4.2. and 4.3. for testing procedures. 5.4. PRECAUTIONS. 5.4.1. The DK100/DK130 Beacons must not be exposed to heat in excess of 160°F (71°C). 5.4.2. The beacon must not be disassembled in any way. Any disassembly of the beacon will void the warranty.
MAINTENANCE DK120/DK140 6.1. GENERAL. This section contains DK120/DK140 Beacon cleaning, beacon testing, battery replacement and testing, disposal and storage procedures. Initially beacons must be tested at every installation or battery change. The required schedule for Bat- tery Replacement and Off-Current Testing is every six years.
O-ring groove and threads. NOTE: O-ring, lubricant and battery are provided in battery replacement kit see Figure 19 for battery kit number.

USE OF AN UNAUTHO- RIZED BATTERY WILL VOID THE WARRANTY AND MAY CAUSE AN INOPERATIVE OR DANGEROUS CONDITION. USE OF AN UNAU- THORIZED BATTERY MAY PRESENT A RISK OF FIRE OR EXPLOSION.
Figure 21. RBB Label Placement 6.7. BEACON OFF-CURRENT TEST. Connect test leads as shown in Figure 22 and check for current leakage between battery and beacon body. The battery OFF current must be less than 3 microamperes. Beacons with greater than 3 microamperes OFF current should be taken out of service immediately.
DK140 Underwater Acoustic Beacon (hereafter referred to as the “unit”) will be free from defects in materials and workmanship for six years from the date of shipment from Dukane Corporation. Dukane Corporation will remanufacture or replace any unit or battery found not to be in conformity with this warranty.
