    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.

  • Page 11: Figure 6. N30a21a Mounting Kit And Beacon Overall Dimensions

    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.

    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.

  • Page 15: Section Iii, Operation, Theory Of Operation, Figure 15. Nominal Pulse Train

    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.
