1 Introduction
1.1 Overview
TX7211 Addressable Sounder Circuit Module unit is an addressable interface module, which will
integrate conventional detectors or conventional manual call points to addressable system. When
any of the connected devices alarms are active, the unit can send the alarm message to fire alarm
controller, which generates alarm signal and displays its address. The unit can match with the
conventional optical smoke detector, conventional rate of rise and fixed temperature detector and
conventional manual call point etc. 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 detectors.
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 Tand to avoid addressable communication compatibility problem.
