Intelligent Input/Output Unit Twin

The Intelligent Twin Input/Output Unit offers the functionality of two independent I/O interfaces within a single, compact enclosure. Designed for integration with intelligent fire alarm systems, this unit simplifies complex configurations by allowing dual channel control and monitoring through separate addressable inputs and outputs. Each side can be independently addressed via DIL switches, enabling seamless operation in large-scale installations. With enhanced wiring accessibility and a robust enclosure, it supports both surface and flush mounting options, making it an ideal choice for versatile system integration. The unit meets BS 7273-4 requirements and includes failsafe operation, ensuring performance even in fault conditions.
