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.

detector conferring to the site situation and environmental requirements.
Program a unique address number for each device according to the project layout before placing
from the Terminal Base.
Warning: Disconnect the loop connection whilst connecting to the handheld programmer.
3.2 Write: Addressing
1. Connect the programming cable to 1 and
6 terminals (Figure 3). Press “Power” to
switch on the unit.
2. Switch-on the programmer, then press
button “Write” or number “2”to enter Write
Address mode (Figure 4).
3. Input the desire device address value from
1 to 254, and then press “Write” to save the
new address (Figure 5).
Note: If display “Success”, means the
entered address is confirmed. If display
“Fail”, means failure to program the
address (Figure 6).
4.Press “Exit”key to go back Main Menu. Press “Power”key to switch-off the programmer.

4 General Maintenance
1. Inform the suitable personnel before conducting the maintenance.
2. Disable the detector on the control panel to prevent false alarm.
3. Do not attempt to adjust or modify the detector, it may affect the ability of the detector to
respond to a fire condition and will void the manufacturer’s warranty.
4. Use a damp cloth to clean the detector. Do not use cleaning chemicals that may leave
residue on the electronic parts and smoke chamber.
5. Notify again proper personnel after conducting the maintenance and make sure to enable
the detector and confirm if up and running.
6. Perform the maintenance on semi-annually or quarterly depending on the site conditions.
4.1 Cleaning
1. Remove the detector cover by snooping away the four sides
tabs using a flat screw driver and then pulling the cover from
the base. (Figure 11)
2. Remove the protective screen by pulling it straight out. (Figure
12).
3. Carefully vacuum the chamber and screen. If there is stain,
wash with running water and ensure it is completely dry.
4. Position the chamber and screen by aligning three tiny holes
over the sensing component. (Figure 12).
5. Align the LED tube and tabs and gently pushing the cover until
it locks into place. (Figure 12).
6. Re-install and test the detector.

Appendix 1
Limitation of Smoke & Heat Detectors
The Smoke & Heat detector is designed for triggering and initiating emergency fire equipment’s,
however it only functions when matching with other equipment’s. Installation of this Smoke & Heat
detector must conform to electrical codes and standards in your country.
All kinds of Smoke & Heat detector have restrictions, since fire develops in varies ways and are often
unpredictable in their progression, it is unforeseeable which type of detector will provide the earliest
warning. No types of Smoke & Heat detector can sense every form of fire all the time. Generally
speaking, detectors may not warn you about fire caused by insufficient safety measures, violent
explosions, leaking gas, improper storage of flammable materials like diluents and other safety
hazards, arson or children playing with fire. The alarm of a Smoke & Heat detector used in high
velocity environment will be delayed due to dilution of smoke by frequent and fast airflow. What’s
more, the Smoke & Heat detector has to be frequently maintained for it is exposed to more dust
contamination.
The Smoke & Heat detector cannot last forever. In order to keep the detector working in good
condition, please maintain the equipment continuously according to recommendations from
manufacturers and relative nation codes and laws. Take specific maintenance measures on the
basis of different environments.
The Smoke & Heat detector contains electronic parts. Even though it is made to last for a long
period of time, any of these parts could fail at any time. Therefore, test your smoke detector at least
every half-year according to national codes or laws. Any Smoke & Heat detectors, fire alarm
devices or any other components of the system must be repaired and/or replaced immediately as
they fail.
