1 Introduction
1.1 Overview
The TX7320 Addressable Sounder is alarm warning device used to notify persons in the vicinity of the
occurrence fire emergency in order the person to take appropriate measures. The unit adopt multi-
application device starting from the types, parameters and wiring layout in single unit. Parameters
can be configured according to the requirement which include alarm tone from 17 different tones,
single address or dual address mode and also setting of power mode to low current consumption in
a simple programing.
The unit manufactured base on the requirement of EN 54 part 3, 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 T&A, to avoid addressable communication compatibility problem.
