1 Introduction
1.1 Overview
The TX7120 Intelligent Addressable Optical Smoke & Heat Detector is the ideal device for most
applications, due to its spiffing linear response to a wide variety of different types of smoke patterns
and combining with heat sensing sensor for temperature response. The unit manufactured base on
the sensitivity requirement of EN 54 part 29, European Standard. The unit is aesthetically pleasing with
unobtrusive design that will complement modern building designs. The unit incorporates an
intelligent processor that provides Algorithm map, inbuilt A/D converter, Drift compensation, and
Self-Diagnosis and History log.
Secure and speedy communication through the on-board processor enables the detector to make
its own decision, resulting in greater automation. In the event of fire, the integral microprocessor
analyses the signal according to factors such as signal strength and rate of increase, then confirms
these patterns with the pre-programmed fire scenarios, smoke and heat patterns including rate of
rise temperature, for a faster and safer response. Once it is confirmed, the LED indicates the sensor
status and parallel sending communication signal to the control panel. The TX7120 detector is
compatible to the TX7004 Analogue Intelligent Fire Alarm Control Panel, produced by single
manufacture T&A, to avoid addressable communication compatibility problem.
