The TX7232 manufactured base on the require- ment of EN 54 part 17, European Standard. In the event of short circuit on the detection loop the TX7232 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 base mount short circuit isolator 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 unobtru- sive design that will complement modern building designs and used to mount intelligent TX7100 smoke detector, TX7110 heat detec- tor and TX7120 multi-sensor. The TX7232 base mount short circuit isolator is compatible to the TX7004 / TX7002 Analogue Intelligent Fire Alarm Control Panel, produced by single manufacture T&A, to avoid addressable com- munication compatibility problem.
