NOTICES
1.
This document discloses subject matter in which Artex Aircraft Supplies, Inc. has proprietary
rights. Neither receipt nor possession thereof confers or transfers any right to reproduce or
disclose the document, any part thereof, any information therein, or any physical article or device,
or practice any method or process except by written permission from or written agreement with

570-0049 Revision -
SYSTEM OVERVIEW
Due to the range of ELT installation available, this manual does not illustrate each single wiring
diagram pertaining to a specific ELT because the wiring is in fact very generic to all Artex
beacons. All Artex ELTs follow the same wiring criteria, and have 5 basic electrical lines
connecting the toggle switch to the beacon:
1. Light: This pin turns ON the toggle switch LED. The ELT output is a square wave
pulse with 280 millisecond period. The ON period of the pulse is 140 milliseconds
and the OFF period is 140 milliseconds.
2. Reset 1: This pin enables the ELT to determine the ON or ARM position of the toggle
switch.
3. Reset 2: This pin enables the ELT to determine the ON or ARM position of the toggle
switch.
4. External ON: This pin turns ON the ELT when it is grounded.
5. Ground: This pin is tied to Aircraft DC ground and references all control input and
output signals.
The interface system alleviates the need to install the 5 electrical wires across the aircraft when
the ELT and the toggle switch are installed apart. As such, the system uses 2 interfaces to
convert the typical 5-wire communication line down to 2 wires.
The ELT interface 453-0041 has a built-in horn that is powered by the ELT.
Upon initialization of either the ELT or the toggle switch 140-3349, the event communication
latency between these two products is less than 2 seconds. As such, a change in the lamp state
(LED) also takes place within 2 seconds.
Once the system is operational, the standard LED flash rate is ~140 msec.
The quiescent state power consumption (with the toggle switch in the “ARM” position) of the
interfaces is less than 100µA.
The color of the two communication wires between the interfaces is inconsequential, but each
wire must:
1.
Have the proper gauge (22-26).
2.
Be properly connected to the appropriate contact on the D-sub mating connector of
each interface as shown in the appropriate wiring diagram.
The voltage range of the 453-0032 interface is 6.5 to 30 VDC, but aircraft power is typically 14
and 28 VDC.
The interface 453-0041 contains a latching relay so a slight clinking noise should be expected
during operation.
4.
CABLE HARNESS
Due to the large array of configurations possible, Artex Aircraft Supplies, Inc. does not provide a
harness as part of the installation of the ELT. Accordingly, it is the responsibility of the installer:
1. To manufacture the required harness(es) and ensure that the wires are adequate for
the installation.
2. To check the integrity of the 2-communication wires installed across the aircraft.
3. To thoroughly check the integrity of any wires used in the installation to lessen wiring
problems and increase operational readiness.
4. To follow standard aircraft wiring practices.

The D-sub crimp contact 151-0042 accepts 22 to 26 AWG wires and is used with Tyco crimping
tool 91525-1 or equivalent.
Artex recommends using a shielded cable to prevent signals related to power frequency, audio
frequency and electrical transients generated from on-board equipments from interfering with the
ELT operation.
The mating connector and contacts connecting to the ELT are found in the install kit included in
the pack list at the time the beacon is purchased. Accordingly, the hardware included in the 4550032 and 455-0041 is only used to connect each interface together.
The interfaces 453-0032 and 453-0041 adequately communicate and allow operation of the
toggle switch 140-3349 with the ELT when using 26 AWG wires with a length of 240 ft (73
meters). Other combinations of length and gauge size must be tested on a case by case basis to
ensure proper communication between the ELT and the toggle switch.
4.1
INSULATION ADJUSTMENT PROCEDURE
On many tools, the insulation barrel crimp height is regulated by the Insulation Adjustment Knob
(Figure 2). The insulation crimp should hold the insulation firmly without cutting into it. To
determine the proper insulation crimp setting, test crimp a loose piece contact using the setting
which corresponds to the insulation diameter:
-
(1) for small
-
(2) and (3) for medium
-
(4) for large
D-Sub Crimp:
Do NOT cut or nick the wire strands during
wire stripping.
Contact crimp 151-0042 accepts wire AWG 22 through 26.

The interface has two connections available on the D-sub connector to connect either aircraft
power 14 VDC or 28 VDC. The connections have internal current limiting resistors to protect the
built-in LED on the toggle switch, so it is critical to establish the proper connection between the
interface, the toggle switch, and the aircraft power.
The power supply inside the interface is designed to operate on 6.5 to 30 V input. Due to this
wide input range, a switching power supply is used to create 5 V for power distribution throughout
the system. This switching supply allows the system to draw on average approximately 125 µA
from a 14 V battery and 65 µA from a 28 V battery.

DIODES INSTALLATION
Ensure that the leads of the diodes do not touch the body of the toggle
switch, or any other contacts other than the ones mentioned below.
7.1.1
Solder the diodes 120-4007 to the toggle switch according to the following information:

The wires for the interface 453-0032 are crimped and inserted inside the D-sub connector 1500022 using the same procedure highlighted in the “Cable Harness” section.
NOTE: Do not close the backshell if the two communication wires have not been installed yet.
Refer to section “453-0032 wiring to 453-0041” in this document to complete the entire
wiring process.
7.4.2
Install the D-sub connector inside a backshell (151-0006) at the completion of the crimping
process.
7.4.3
Secure the strain relief using the screws provided in the backshell kit.
7.4.4
Install the thumbscrews and close the backshell with the screws.
7.4.5
Attach the backshell to the 453-0032 interface using a torque between 1.5 and 2.0 in-lb (.7 to .22
Nm) at the completion of the entire wiring process.
NOTE: Accidently attaching the interface 453-0041 to the backshell instead of the 453-0032 does
not harm the ELT, the toggle switch 140-3349, or any of the interfaces. The outcome is
that the ELT cannot be activated remotely through the toggle switch 140-3349.
