SECTION II
INSTALLATION
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 BEA-
CON.
NOTE
All installations to Cockpit Voice Recorders and
Flight Data Recorders should be in accordance
with the recorder manufacturer’s approved proce-
dures and hardware.
2.3. SURVIVABILITY.
2.3.1. The beacon location should minimize the proba-
bility of physical damage to the device during water
impact. The aft mid section of the aircraft is normally
the most desirable location for the beacon, but con-
sideration must be given to environmental conditions
outlined in Section 2.4.
2.3.2. The area selected for the beacon mounting should
be free of the possibility of heavy equipment tearing
loose and striking the device.
2.3.3. Installation should be made to a substantial
structural member, but kept as simple as possible
and must not weaken the structural member.
2.4. ENVIRONMENTAL.
2.4.1. The DK Series beacon must not be disas-
sembled, crushed, penetrated, incinerated or exposed
to temperatures above 160°F (71°C).
2.4.2. The beacon is a battery powered device and
installed shelf life is affected by higher than normal
temperatures. Maximum temperature must not ex-
ceed 160°F (71°C).
2.4.3. Inadvertent actuation of the water switch by any
source of water, such as rain, salt spray, melting ice or
snow, head or washroom overflow, foods and beverages,
must be avoided.
2.4.4. In order to avoid accumulation of moisture on
the water switch, the device should be mounted
with the long axis of the beacon horizontal or with
the water switch facing down. A clean switch will
allow moisture to collect into droplets and run off the
switch, without activating the beacon.
2.4.5. Honeycomb structure, tarpaulin fabrics, cloth-
ing, parachutes, cargo, etc., are sound absorbing ma-
terials. Do not surround the device with these materi-
als and if necessary, remove small areas of such ma-
terials from the immediate vicinity.
2.4.6. Any compartment that may not be expected to
flood under light impact should not be used. Direct
contact between the beacon case and water is neces-
sary for actuation and acoustic radiation.
2.5. MAINTENANCE.
In addition to observance of the preceding manda-
tory considerations, where possible the selection of
a mounting location should provide for convenient
beacon access during inspection intervals. The prop-
er mounting location should also provide for clear-
ance for removing the beacon from its mounting hard-
ware.
