Loop Protection. Fault Isolation. System Continuity. The GULF ALARM® Addressable Isolator Module is designed to protect fire alarm loop circuits by automatically isolating short circuit faults. In the event of a wiring fault, the module isolates the affected section of the loop, allowing the remaining system devices to continue operating without interruption. Integrated with intelligent addressable technology, the isolator module ensures enhanced system reliability and compliance with modern fire alarm installation standards.
