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.

2 Installation
2.1 Installation Preparation
This sensor must be installed, commissioned and maintained by a qualified or factory trained service
personnel. The installation must be installed in compliance with all local codes having a jurisdiction in
your area or BS 5839 Part 1 and EN54.
The TX7120 Smoke & Heat detectors operate on the principle of infra-red light refracting off smoke
particles entering the chambers. This makes detector more sensitive to smouldering fires such as
modern fabric or furnishing. Optical detectors are more prone to false alarm from steam or dusty
environment. For best sensing ability, avoid installing the smoke detector in these areas.
In open air applications as the detectors require ceilings to direct the smoke from the plume
by convection.
On side walls, this will severely delay the response time of a detector and where ceiling
heights exceed 10.5m.
In Rooms where cooking will take place such kitchens, or similar areas where steam and
condensation are present.
Where exhaust fumes are present like car parks.
Where smoke particles will not be produced by fire.
Plant Rooms (unless full discussions regarding the room contents and status subject to a fire
have been made between Client and Manufacturer), Boiler and Generator Rooms.
2.2 Installation and Wiring
1. Mount the T&A standard base on standard one [1] gang electrical
back box. Do not over-tighten the screws otherwise the base will
twist. Use M4 standard screws.
2. Connect the wire in terminal as shown in Figure two [2]. Verify the
device number or other device parameters if desired using
handheld programmer then stick on the label before attaching
detector. The sticker labels are available on the control panel.
3. Attach the detector to the base, point the detector in the base by
the mark-line and secure the detector in that position by rotating it
clockwise, until it reaches the next mark line.
4. Do not remove the red plastic dust cover until the final handover is
done.
