The GDS Defender gas leak detection system features remote sensors connected to the main control unit via a 3 core cable network. The control unit is an advanced design using the latest technology and provides a high integrity system whilst offering a significant cost saving over conventional gas alarm systems.
The GDS Defender is GDS’s lowest cost gas detection system, with remote sensors wired back to the control unit on a simple 3 core cable. GDS lists it for swimming pools, breweries and car parks, and it can later join a GDS Combi CANbus network if the site grows. We supply, install, commission and service Defender systems.
