4. HARNESS
Due to the large array of configurations possible, ACR Electronics, Inc. does not provide a
harness or RJ11 plugs (telephone connector) as part of the installation of the ELT. Accordingly,
it is the responsibility of the installer to manufacture a harness or ensure that the existing
harness is adequate for the installation.
The harness must be manufactured following the cross-wired configuration mentioned in
Subsection 6.2.
NOTE: Refer to Subsection 6.1 for Ameri-King and ACK retrofit installations.
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.
Although it might be appropriate to use a telephone line (minimum UL flammability rating VW-
1) in some instances, each installation is different and should be evaluated on a case by case
basis. Accordingly, it is the responsibility of the ELT installer to ensure that the installations
follow FAA regulations such as but not limited to Advisory Circular 43.13.
Refer to the installation section of any of the ME406 series manuals for ELT related information.
