Today we are excited to launch our new 2-Wire gas detection systems. This major product launch represents a step change in gas detection. All devices connect addressably using two core cable for both power and communication. Detectors are now termed ‘detector nodes’ as each detection point now also has multiple I/O capability. Two controllers are offered with the system as well as a range of accessories, battery backup, relay modules etc. The system uses Android apps for service, backup and information download.
