User manual ACR ELECTRONICS ARX-50

[. . . ] 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. A two-wire connection (ground negative) is required that is capable of supplying 120 mA average and up to 400 mA under an alarm condition at +10. 5 to +28 V DC. SECTION 3 - INSTALLATION Mount the bracket After selecting the location, hold the ARX-50 bracket in position and use as a template to mark where the screws will be located. [. . . ] 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. Turn on the ARX-50 The red OFF LED will be illuminated while the system is turned off, yet is still connected to a power supply. To turn on the ARX-50, depress the On/Off button. The LEDs will blink on and off, and the green On LED will illuminate. Set to default at the factory, the alarm mode is active on channel 121. 5 MHz. Some signal level indicators may flicker while the unit searches for a signal. Choose Alarm mode or Monitor mode Alarm mode The Alarm mode for the ARX-50 is the system's default mode. In this mode, the radio beacon signal detector circuitry is activated, i. e. , The system is ready to detect 121. 5 MHz signals. In Alarm mode, the speaker is silenced until a 121. 5 MHz beacon signal is detected, at which time a loud audible siren and a flashing bright red LED are activated. The ARX-50 detects an activated Mini BTM300 beacon, and other activated beacons that transmit 121. 5 MHz signals. The ARX-50 is designed to only detect an alarm on 121. 5 MHz signals that originate from an activated beacon. The signal strength meter is always active in this mode. If there is a strong signal that is not from a beacon, the signal strength will still be displayed on the signal strength meter, but the ARX-50 will not alarm. Monitor High mode This mode is intended for advanced users to obtain more information about a received signal. NOTE: The ARX-50 reverts back to Alarm mode after 15 minutes in Monitor High mode. In the monitor modes, the ARX-50 detector circuitry is deactivated. The demodulated 121. 5 MHz audio signal is annunciated at all times. If there is not any signal on the 121. 5 MHz carrier, whether activated beacon or other source, static will be audible. The speaker volume is high, and the signal strength meter is active. Y1-03-0229C 7 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. [. . . ] Reproduction in whole or in part is permitted only with permission of ACR Electronics, Inc.
