AUDIO UNITS IN ENTRANCE PANELS WITH PUSHBUTTONSTechnical data regarding the various models of audio unit which can be incorporated in the upper entrance panel modules is givenin the following pages.1Cod. 9610028GRF-201ELECTRONIC AUDIO UNITAudio unit for standard installations of door entry system with electronic call. Conventional 4+N connectionsystem. Generation of electronic call with acoustic confirmation for the visitor.The audio unit incorporates a microphone, a loudspeaker, a pushbutton to illuminate the card-holders of theentrance panel (1), volume controls both for the panel (2) and for telephones (3), and jumper for the configurationof the call tone: either double-tone or triple-tone (4). It also includes lift-up type connection terminals toensure correct connection.The electronic circuit is protected against short circuits.Operating temperature -10 to + 55 °CDescription of terminals and typical voltages depending on the condition of the equipmentin door entry installations and in door entry installations with internal communication:Note: The voltages shown here are reference values provided for testing of equipment. Do not use the terminalsof the equipment to supply power to additional devices without previously consulting the manufacturer.TERMINALSAT RESTWORKING2 34V , 12 VGRF-201cod. 9610028Made in Spain3 2 J2V , Power supply voltage1 , 2 Telephone lock release3 , 2 Telephones microphone4 , 2 Telephones loudspeaker7 , 2 Common push button terminal1 , 23 , 24 , 218 V9 V0 V0 V5.6 - 6.6 VAudio max. 4 VppAudio max. 7.0 Vpp12 V~V~9 10 11 121 2 3 479 , 1011 , 12J2Panel lightingElectric lockSelecting the electronic call tone7 , 29 VTone max. 7.0 Vpp9 V9 , 100 V12 V21Cod. 9610029GRF-20311 , 12ELECTRONIC AUDIO UNIT. SEVERAL POINTS OF ENTRYAudio unit with built-in microprocessor for door entry installations in buildings with several points of entry.Capable of controlling the priorities of the different points of entry of the installation directly, i.e. withoutrequiring audio selectors. Conventional 4+N connection system. Generation of electronic call with acousticconfirmation for the visitor.Note: In installations where a buzzer call is required, the audio unit must be used in conjunction with thecall adaptor accessory. See the technical data in the section “Call Adapter Accessories” on page 87.The audio unit incorporates a microphone, a loudspeaker, a pushbutton to illuminate the card-holders of theentrance panel (1), a red light which indicates when the panel is disabled (2), volume controls both for thepanel (3) and for telephones (4), jumper for precision adjustment of sound level (5) and jumper for the configurationof the main panel (6): the main panel determines the panel with which telephones on standby arein communication.The unit also includes elevator-type connection terminals to ensure correct connectionThe electronic circuit is protected against short circuits.0 V12 VOperating temperature -10 to + 55 °C59
