Installation & Operation Manual
1 Introduction
1.1 Overview
The TX7322 Addressable Sounder Base is an 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.
The TX7322 Addressable Sounder Base is powered by the communication bus. The TX7322 can
change into different encoding modes such as non-coding mode, single-encoding mode and dual-
encoding mode using a programming tool.
And it has different starting modes. In addition, the
