TX7211 Addressable Sounder Circuit Module TX7211 Addressable Sounder Circuit Module

The unit manufactured base on the requirement of EN 54 part 18, European Standard. The unit is aesthetically pleasing with unobtrusive design that will complement modern building designs and its plug-in type assembles make installation and maintenance more convenient to the installer. The unit is compatible to the TX7004 Analogue Intelligent Fire Alarm Control Panel, produced by single manufacture Tanda to avoid addressable communication compatibility problem.

TX7211 Addressable Sounder Circuit Module unit is an addressable interface module, which will integrate conventional sounder or bell to addressable system. When any of the connected devices alarms are active, the unit can receive the alarm message from fire alarm controller, which generates alarm signal and displays its address. The unit can match with the conventional sounder or bell. It has the function of checking short or open circuit of the output connection, by the End of Line Resistor (EOLR). The fault massage includes open circuit, short circuit or any removal of the conventional sounder or bell.
