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 addressable sounder circuit module can receive the alarm message from fire alarm controller, which generates alarm signal and displays its address. The TX7211 Addressable Sounder Circuit Module unit can match with the conventional sounder or bell. TX7211 Addressable Sounder Circuit Module unit 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.
