Wide-angle color camera with integrated loudspeaker module with 2 call buttons for installing audio/video systems in 2-wire technology. Color camera with 1/3' sensor for extended detection range (135° horizontal/96° vertical) including LEDs for illuminating the detection area and anti-fog heating (heating resistor). With adjustment of the volume of the loudspeaker and microphone. For managing up to 98 call buttons via the code lock/keyboard module or with 2-row call button modules. Up to 49 call buttons are possible with 1-row call button modules. The door opener (max. 30 Ohm internal resistance) is connected directly to the S+ and S- terminals (18 V 4 A surge current - 250 mA holding current). An external door opener button (e.g. postal lock) can be integrated via the PL terminals. An additional power supply unit can be connected to terminals 1 and 2 (e.g. in large systems with several door stations). The device is equipped with several status LEDs that indicate the following operating states: door open, communication active, call made and system busy. Integrated brightness sensor for automatically switching on the background lighting in the dark. To be completed with the corresponding front panel. The device is configured either with configurators or via PC and TiSferaDesign software. Note: - When using the left call button on the loudspeaker module or the 2-row call button modules, the jumper (J1) must be pulled.
