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. 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). This allows users to become familiar with the operation of the ARX-50 by using a special training beacon operating on the same frequency. This way, local Search and Rescue authorities are not notified. NOTE: The ARX-50 reverts back to 121.5 MHz after 1 hour in Training mode. Activation and alarm indicators The ARX-50 is a fully automatic monitor/receiver. In Alarm mode, once the ARX-50 detects a signal, a loud audible alarm will sound and a bright red LED will flash. Signal strength meter The eight LEDs on the signal strength meter are capable of indicating sixteen levels of received signal strength. The signal strength meter provides the user with an indication of how far away the 121.5 MHz signal might be. The higher the LEDs are illuminated, the stronger the 121.5 MHz transmitted signal is, and the closer the signal is relative to the ARX-50. The reverse is also true: The lower the lit LEDs are, the less signal strength, and the further away the beacon is relative to the ARX-50. NOTE: The signal strength meter may display a low level of activity any time that the ARX-50 is on. This is not to be mistaken for detection of a 121.5 MHz beacon transmission. SECTION 5 - MAINTENANCE The following maintenance schedule is recommended: Action Description Frequency Visual inspection Inspect the antenna, cables and connections. Ensure that the cable is attached properly and the unit has not been damaged. Every 6 months Performance test Verify that the system is operating by using the training mode with a training beacon Every year Clean exterior Using a mild, sudsy solution such as dishwashing liquid, wipe the surface of the ARX-50 with a damp cloth to remove film, salt and sand As needed APPENDIX A - SPECIFICATIONS General Carrier frequency 121.5 MHz or 121.65 MHz, user selectable Sensitivity <0.2 .V (at antenna output) VHF antenna Flexible monopole Modulation Swept tone Electrical input power +10.5 V to +28 V DC, 120 mA average, 400 mA maximum Alert methods Bright red flashing led Loud audible alarm (.70dBA @ 1m) External speaker connection (8v maximum) Relay contacts: normally open (2 A/30 V maximum) Regulation conformity Safety IEC 60945, EN50371 EMI/EMC IEC 60945 RoHS/WEEE European Directive 2002/95/EC Physical Dimensions 5.3” X 3.7” X 1.5” (13.46 X 9.40 X 3.81cm) Weather resistance IP65 (when included monopole antenna is correctly installed) Operating temperature -4°F to +131°F(-20°C to +55°C) Storage temperature -40°F to +158°F (-40°C TO +70°C) Weight 0.8 lbs (362.87 g) APPENDIX B - ACCESSORIES The following are items that can be ordered for your alarm receiver: Description ACR Part Number Mini B™300 ILS H2ON (water activated) 2767 Mini B™300 ILS (manually activated) 2766.6 APPENDIX C - WARRANTY, USEFUL LIFE POLICY, NOTICES Limited Warranty This product is warranted against factory defects in material and workmanship for a period of 1 (one) year* from date of purchase or receipt as a gift.
