ACR Electronics, Inc. 1. 570-0049 Revision B INTRODUCTION This manual contains detailed information about the installation and operation of the interfaces 453-0032 and 453-0041 with any Artex Emergency Locator Transmitters. The interfaces do not function with the ELT-200 series. The intent of the interface system is to provide a cost effective means to our customers to retrofit existing ELT installations using 2-wire connection between the ELT and a toggle switch.

ACR Electronics, Inc. 3.2 570-0049 Revision B WIRING 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.

ACR Electronics, Inc. 4. 570-0049 Revision B CABLE HARNESS Due to the large array of configurations possible, ACR Electronics, 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.

ACR Electronics, Inc. 570-0049 Revision B Figure 2: Tyco Crimping Tool Figure 3: Crimp Overview 4.2.11 Hold the contact in this position and squeeze the tool handles together until the insulation anvil starts entry into the insulation crimper (usually two ratchet clicks). Do NOT deform the insulation barrel or wire barrel. 4.2.12 Insert a properly stripped wire through the locator slot and into the wire barrel of the contact until the insulation butts against the locator/insulation stop. 4.2.

ACR Electronics, Inc. 7. 570-0049 Revision B 453-0032 WIRING TO 140-3349 TOGGLE SWITCH 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.
