circular con nector as shown in Fig ures
3-10 and 3-11. The cir cu lar con nector
will fit through the rect angular open ing
in the mount ing frame cap.
Please note the pin ori entation as
shown in Fig ure 3-10 is look ing at
the rear of the cir cu lar con nec tor

3.6.4. Wiring Re mote Switch
Assembly 9-pin Con nec tor
Be fore in serting the ca ble pins into
the 9-pin con nec tor for the cock pit
switch as sembly, strip and crimp a fe -
male ter minal pin to a sep arate
shorter wire for con nec tion be tween

craft ground. Strip and crimp a fe -
male pin to a sec ond wire for
con nec tion be tween air craft power and
the power con nec tion (pin 3) on the
cockpit switch con nec tor.
In sert each of the fe male pins into
the switch 9-pin con nector, which will
con nect to the cock pit re mote switch,
as shown in the wir ing di a gram (Fig -

3.6.5. Power and Ground
+28 VDC air craft power is re quired to
operate the nav igation func tion of the
C406-N. Air craft power also pro vides
power for the cock pit re mote panel
light func tions but has no ef fect on
the switch func tions. The ELT will ac -
tivate and trans mit an emer gency sig -
nal (less po sition data) without +28
VDC. Should +28 VDC air craft power
be lost in flight, prior to a crash, the
ELT will re tain the last known po sition
from the ARINC 429 source for 36
seconds. The ELT power must be
wired via a breaker or switch since
the ELT cir cuitry will draw cur rent
whenever power is ap plied. ARTEX
rec om mends that the re mote switch
be wired di rectly to the air craft bat -
tery.
If your ELT front panel in dicator light
is wired through ei ther the air craft
mas ter or the avi on ics mas ter switch,
make sure these switches are turned
on dur ing test ing.
3.6.6. Finishing Up
With its switch in the “OFF” po sition
(down), in sert the ELT into the mount -
ing tray at an an gle so that the lock -
ing ears at the end op po site the
direction-of-flight ar row fit into the
mounting tray lock ing slots. Press the
ELT down into the mount ing tray un til
fully seated.
In stall the pro tec tive top cover on the
ELT by fit ting the cover lock ing slots
over the lock ing ears on the ELT.
Push the cover to ward the con nec tor
end of the ELT and seat it down in
place on the ELT.
In sert the an tenna coax ca ble through
the end cap ac cess hole and con nect
to the ELT unit. Feed the 22-pin cir -
cu lar con nector through the end cap
and con nect to the ELT con nec tor.
Slide the end cap into place over the
mount ing tray and pro tective top
cover and se cure the end cap to the
mount ing tray us ing the two thumb -
screws. Do not tighten over 18 in-lbs.
Tie up ex cess slack in the coax ca -
ble, yet leave enough slack to al low
for a drip loop and also so that the
mount ing tray cap can be eas ily re -
moved.
Per form the tests as out lined herein.
It is VERY im portant that the cock pit
switch panel light im mediately be gins
flashing when the ELT is ac ti vated. If
the light fails to start flash ing im medi -
ately, re check the in ter face wir ing be -
