SECTION 1 - HOW THE ARX-50 WORKS The ARX-50 alarm receiver is designed as a companion to the ACR radio beacon transmitter model number RBL-30 (Mini B™300). It is intended to be used in a crew overboard (COB) alerting application. When properly powered and fitted with an external antenna, the signals from the Mini B™300 transmitter can be received by the ARX-50 up to several miles.

Location selection Choose a dry, clean surface to install the ARX-50, giving consideration to the importance of the location. The user must be able to see the visual alarm and hear the audible alarm. CAUTION: When using the included antenna, the ARX-50 must be mounted vertically and the antenna must not be within 0.5 m of a metal panel or other metal objects. Ship’s power requirements The ARX-50 accepts ship’s power supply in the range of +10.5 to +28 V DC.
Connect the power supply The ship’s power supply is the source of power for the ARX-50. A onemeter I/O cable is supplied with the product. It is recommended that a qualified marine electronics professional or qualified electrician connect the power.
The ARX-50 has three large, circular push buttons and seven LEDs that indicate settings. The push buttons switch between alternate modes. Each button is assigned a set of functions. See Figure 1. Each button “beeps” when depressed. The LED indicators are either red or green to signify the system mode. Green LEDs signify that the system is in a normal state and red LEDs signify that the system is in an atypical state.
Monitor Low mode This mode is identical to the Monitor High mode except that the speaker volume is lower. NOTE: The ARX-50 reverts back to Alarm mode after 15 minutes in Monitor High mode. Training mode Operation in Training mode is identical to the live radio beacon detection mode. In Training mode, the ARX-50 receives a special training frequency (typically 121.65 MHz or 121.775 MHz).
