Purpose
Digital duplex 3-wired cabling communicative system Client-Casier Digital Duplex DD-215T is worked out on the base of audio processor Motorolla is oriented to perform the working scheme "client-cashier" via soundproof window barrier. The DD-215T is a main component of security systems in currency exchange offices. 8 independent noise detectors are used in the system, which are adopted to the surrounding background noise. Digital Adaptive Detector (DAD) - is a digital adaptive detector of activity which helps to reduce unwanted background noise within several seconds period after long-time pauses. The using of such system is quite effective, for example, in trading centers, in airports and on railway stations, where the level of background noise is sufficiently high. Client can talk by himself and listen to operator at the same time. But Operator can regulate volume and microphone sensitivity according to situation. In case of necessity, microphone can be switched off and client will be unable to hear anything behind the soundproof window barrier.
DD-215T was worked out as a mani component of banking equipment for exchange cash-desks.
Operator Call Button is available on the Impact-Proof panel. Call Button - is a universal device for such class equipment. Operator has much more freedom and mobility with Digital Duplex. He should't stay at the same place all working day long. Signalling Tone will inform an Operator when any client appeares.
Capacity
Our system is provided for digital enrollments, particuraly, the light-emitting-diode adjustment status. Built-in nonvolatile storage of current sensitivity adjustments and of loudness level, in case if electricity supply is cut, will help to store the latest operator's adjustments. And if the system will be switched on again, it will come back to the latest adjustments automatically. Sound keystroke, the tone of which can be changed, will help operator to identify the level of loudness and sensitivity the system is adjusted at the present moment. Digital technologies, digital operator's voice detector and automatically regulation of client's voice increasing level are used in the present model. as well as in the previouse one. Line Out helps to output sound on external dynamic, loudspeaker, to make high-qualitative recording of the dialog, when voice-recording device is connected to communicative system. Intergration with video-survaillance and audio-control systems Ewclid is possible. Gooseneck microphone design, worked out in bio-design style, can help to adjust communicative system to the proper level. Thereby operator's position upon communication can be optimal convinient for him.
External Impact-proof Laid-on Panel
External Impact-proof Laid-on panel "Topaz" protect device from mechanical impacts, damages and temperature changings (working regime from -40 to +60). Microphone sensetivity self-tuning, volume self-tuning are used in this model. It's possible to built-in a hidden video-surveilance camera. Double coat of laque on the printed circuit board of the panel makes this model moisture-resisting. Thanks to tampon printing on the operation unit and special powder paint which covers client panel, communicative system remains solid and resistant to any splits and save pre-incident perfection for a long time. Laid-on Abonent panel "Topaz" can be installed in the places, were the intstallation of classical "overall" pannel is impossible, for example, on narrow jambs and gates. Angle fastening , which helps to install the pannel under 45 dergees is included into the set. Installation of the pannel is possible as indoors and outdoors as well.
Cabling
Spreaded Audio processing scheme was founded as a basic princip of DD-215T, which provide the high quality of model productivity. 2 audio processors MOTOROLLA (one is in Operator's Unit and one in Abonent Panel) are used in the model. Light-emitting diod set in the first crack of dynamic just above buttons in order to indicate operation modes of DD-215T. Indification modes are as followes:
- Light-emitting diode is not illuminating - DD-215T is not working
- Ligh-emitting diode is blinking slowely - Microphone is switched off
- Ligh-emitting diode is blinking quickly - Sound is transmitted from Operator to Abonent
- Light-emitting diode is illuminating without blinking - Sound is accepted by Operator from Abonent
Main Components of Operator's Unit
1 - "MIC OFF" Operator's microphone is switched off
2 - "POWER" Power Supply Switched ON/OFF
3 - "-VOLUME" Volume of Operator's Unit is decreasing
4 - "+VOLUME" Volume of Operator's Unit is increasing
5 - "-SENSITIVITY" Sensitivity of Operator's Microphone is decreasing
6 - "+SENSITIVITY" Sensitivity of Operator's Microphone is increasing
Each selecting button "+" or "-" should be accompanied by beep signal. If the highest level of "+" or "-" reached, the tone of beep signal will be changed.
Abonent Panel
1 - Microphone
2 - Dynamic
3 - Fastening Hole
4 - Operator Call Button
