Connect the power supply
The ship’s power supply is the source of power for the ARX-50. A one-
meter I/O cable is supplied with the product.
It is recommended that a qualified marine electronics professional or
qualified electrician connect the power.
Wiring
The 1m I/O cable wiring chart is as follows:
Signal Wire Color
Positive power (12 to 24V nominal) Red
Ground Black
Speaker- Brown
Speaker+ Orange
Relay- common Yellow
Relay- normally open Green
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.
