1 Introduction
1.1 Overview
The TX7230 manufactured base on the requirement of EN 54 part 17, European Standard. In the
event of short circuit on the detection loop the TX7230 Isolators either side of the loop will detect the
problem and open circuit and isolates the faulty part of the loop, enabling other devises on the
unaffected part of the loop to operate normally. The module will continue to monitor for the fault to
be repaired, once the fault is cleared the isolator will automatically reinstate the effected part of the
loop.
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 TX7230 Isolators Module is compatible to the TX7004 Analogue Intelligent Fire Alarm
Control Panel, produced by single manufacture T&A, to avoid addressable communication
compatibility problem.
1.2 Feature and Benefits
 EN54-17 Compliance
 In the event of a short circuit isolates faulty parts of the loop.
 Automatically resetting once the fault has cleared
 Can monitor up to 70 devices
 LED status indicator
 Loop powered device
 Aesthetically pleasing design
 Surface mounting with fix base for simple installation

2 Installation
2.1 Installation Preparation
This interface module 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.
T&A products has available range of interfaces, each interface module is designed for specific
application, it is essential to consider the requirement of both sides of the interface to avoid
malfunction and typical fault scenario. The main caution is to ensure that the voltage rating of the
equipment and interface module are compatible.
2.2 Installation and Wiring
1. Mount the interface module base on standard one gang electrical back box. Follow the
arrow mark for the correct position. Do not over-tighten the screws otherwise the base will
twist. Use two M4 standard screws.
2. Connect the wire in terminal as shown in Figure two [2].
3. Align the interface module and tabs and gently pushing the device until it locks into place.

3 General Maintenance
1. Inform the suitable personnel before conducting the maintenance.
Note: Since Isolator cannot disable from the control panel to prevent false alarm, it is
recommended to temporarily close the loop once the isolator is removed.
2. Do not attempt to repair the circuitry of the interface module, it may affect the operation to
respond to a fire condition and will void the manufacturer’s warranty.
3. Use a damp cloth to clean the surface.
4. Notify again proper personnel after conducting the maintenance and make sure to enable
the interface module and confirm if up and running.
5. Perform the maintenance on semi-annually or depending on the site conditions.

Appendix 1
Limitation of Isolator Module
The Module cannot last forever. In order to keep the module 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.
This module 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 module at least every half-year according to
national codes or laws. Any interface module, fire alarm devices or any other components of the
system must be repaired and/or replaced immediately as they fail.
