Description
The TX7230 Analogue Addressable Isolator Module is a critical safety component designed to maintain the integrity of an addressable fire alarm loop. Its primary role is to automatically isolate short-circuited sections of the loop, ensuring that unaffected devices continue to operate without disruption. Built to EN54-17 standards, the TX7230 enhances system reliability by minimizing downtime and preventing a single fault from disabling the entire loop. With loop-powered operation, automatic reset functionality, and the ability to monitor up to 70 devices, it offers dependable performance and easy installation for indoor fire detection systems.
