reach the switch and see the light. The
re mote switch is re quired for the ELT
to be TSO C126 ap proved. It is not
op tional.
The switch as sem bly re quires a space
about 2" high by about 1" wide both on
the panel sur face and be hind the panel.
Re fer to Fig ure 3-8.
Mark a cut out for the cock pit panel
switch with the di men sions shown in Fig
-
ure 3-8.
In stall the switch as sem bly by fit ting it
into the cut out, mark ing the 4 screw
holes and drill ing them with a #28 (.1405)
drill bit. Use the 4-40 X 1/2" pan head
phillips screws, nuts & lock wash ers pro

3.6. Wiring the 406 Sys tem
CAU TION:
Prior to in stall ing the har ness in the
12-pin re cep ta cle, feed the wire bun dle
through the rect an gu lar hole in the mount -
ing frame cap. The re cep ta cle will not fit
through the mount ing frame cap har ness
en trance if the har ness is in stalled prior
to do ing this.
3.6.1. Fab ri cate the Ca ble
NOTE: If the ELT is to be used with an
Artex ELT/NAV In ter face (P/N 453-6500)
re fer to the ARTEX ELT/NAV In ter face
In stal la tion and Op er a tion Man ual
(570-4602) for wir ing in struc tions. Wires
will need to be run which con nect pins
9, 10, 11 and 12 of the ELT to the
ELT/NAV In ter face unit.
Fab ri cate a 5 wire har ness (22 Gauge
min i mum) long enough to reach be tween
the ELT in stal la tion lo ca tion and the cock
-
pit panel switch lo ca tion. See Fig ure 3-9.
Strip about .150" of in su la tion from the
ends of each of the 5 ca ble wires. Dress
and tin the bare wires to pre vent the
strands from fray ing dur ing the crimp ter-
mi nal in stal la tion.
Fab ri cate an ad di tional wire long enough
to reach from pin 11 of the ELT con nec
-
tor to an air craft ground point. Strip and
pre pare as de scribed above. This wire
will be crimped in the same ter mi nal a s
the wire run ning from pin 11 of the ELT
con nec tor to the cock pit r e mote switch
(i.e. 2 wires ter mi nated at the same
point). Re fer to the de pic tion of pin 11
on Fig ure 3-10. As an al ter na tive, this
wire may be spliced as de scribed in AC
43.13-1A, Sec tion 445 (“Splices in Elec tric
Wire”) if crimp ing both wires in a sin gle
ter mi nal is not prac ti cal.
Re mem ber - the wires at the 12-pin
con nec tor end of the har ness must be
fed through the End Cap As sem bly
prior to in stall ing the con nec tor. Re fer
to Fig ure 3-9 and Sec tion 3.6.2
On one end of the ca ble, use a Molex
crimp tool (Molex Tool # 11-01-0008) or
equiv a lent tool for .062 ter mi nal pins and
crimp the male ter mi nal pins pro vided
(ARTEX P/N 151-6627) to each of the
ca ble wires which will mate with the
12-pin re cep ta cle which con nects to the
ELT. Re mem ber, there will be 2 wires at
pin 11. This end will join to the Molex
con nec tor on the ELT unit.
On the other end of the ca ble, crimp
the fe male ter mi nal pins pro vided (ARTEX
P/N 151-6628), us ing Molex Tool (or
equiv a lent) cited above, to each of the 5
ca ble wires. This end will join with the
Molex con nec tor on the cock pit panel
switch as sem bly.
