Installation options

The ARX-50 is designed to be flexible, allowing for user preferences. For this reason, the system provides relay contacts for a variety of connections.

The relay contacts output in the ARX-50 is a floating metallic switch that closes upon alarm receipt. It is capable of switching a circuit carrying up to two amps, at up to 30 volts. The contacts, which are normally open, can be used for a variety of purposes, including:

Sending input to an external GPS to save position Switching to an external siren or bell for an alarm

An external speaker may also be connected using the speaker wires on the I/O cable.

NOTE: It is recommended that a qualified marine electronics professional or qualified electrician connect such optional devices. While ACR allows customized connections to the ARX-50, non-standard configurations are not supported by ACR due to the number of unknowns and variables involved.

SECTION 4 - OPERATION

Operation overview

The ARX-50 is a 121.5 MHz radio beacon receiver that is part of a ship’s crew overboard (COB) system. To properly protect officers, crew and passengers from COB, each individual will need to wear or carry on their person a locator beacon such as an ACR Mini B™300 series beacon. If the beacon is activated in a COB situation, the ARX-50 receiver will detect the 121.5 MHz signal. Audible and visual alarms will be triggered.
