PointGard is a self-contained gas detection alarm system that is easy to install and commission. Just mount it on a wall and hard wire it to an AC/DC power or plug in the optional AC power cord. Since the strobes and horn are built in, there is no need to specify and purchase separate alarm output devices. The pre-calibrated sensor is ready to use.
The gas sensor type DQ is based on the proven catalytic bead principle. Innovative dual active elements result in very good long-term zero stability. The long service life is resulting from a good poison resistance and provides you with low ownership costs. The innovative gas inlet allows the sensor to respond to gas within a matter of seconds.
PointGard can accommodate additional external alarm devices through its three built-in relays. In addition, a 4–20 mA signal output allows integration into a larger gas detection system.
PointGard’s glass fiber reinforced polyester housing is water and dust resistant with a 4X/IP66 rating. Its compact size allows it easily to fit most applications. Built-in cable glands make it easy to install.
The large, illuminated backlit graphic display shows status information clearly and in a format that’s easy to use. The measured gas concentration, selected gas type, and measuring unit are displayed during normal operation. Coloured LEDs (green, yellow, and red) provide additional alarm and status information. Advanced diagnostics log events and gas readings, which can be displayed and a graph created on the display.
For Cat Ex sensors, flameproof “Ex d” and increased-safety “Ex e” remote sensor enclosures are available for use in hazardous atmospheres.
