Product Details

The GAS 640 range of multi-channel control systems offers an incredibly versatile approach whilst ensuring a reliable safety system across all industries and applications. It has the capacity to monitor up to 64 addressable and 16 direct sensors, 8 of which can be converted to accept mV catalytic sensors. Larger system requirements can also be met with over 1000 addressable sensors, possibly through a networked GAS 640 solution.

Designed to take the user experience to the next level, the GAS 640 can be installed in all customer environments with configurations available as a wall-mounted unit, 19’’ rack system, panel and din rail mount.

GAS 640 features a vast range of optional equipment, including GAS 640 software, enabling full data logging facilities with system management and providing real-time views showing sensor locations, alarm status, and actual gas values.

Designed to operate across multiple industries and applications, the unique system architecture offers flexibility with up to six different control panel options. The intuitive user interface sees parameters set via the front panel or alternatively via PC, and detectors supplied pre-calibrated. GAS 640 can be customised to meet your specific requirements without the need for extensive cabling, providing a comprehensive, highly configurable safety system.
