The GDS 404 has been designed with features that provide an effective response to the detection of gas hazards in a wide range of environments, from commercial premises through to heavy industrial applications requiring hazardous area sensing. Typical monitor locations are public buildings, boiler plant rooms, swimming pools, water treatment works, H&V control systems, manufacturing and processing plants.
The GDS404+ is a wall or rack mounted control panel for one to four gas sensors, built up with plug-in channel cards. GDS lists public buildings, boiler plant rooms, swimming pools, water treatment works and process plants among typical locations, including sites that need hazardous area sensors. We supply, install, commission and service GDS404+ systems.
