Watching a parking garage or loading dock for two gases at once, this fixed detector measures carbon monoxide from 0 to 250 ppm at the main sensor and nitrogen dioxide from 0 to 10 ppm at a remote head, which covers both petrol and diesel exhaust from one device. Three SPDT relays stage ventilation and alarms, and BACnet MS/TP carries the readings to the building controller.

The Q6/B6 Toxic/Combustible Gas Detectors use various sensing technologies to detect a wide assortment of gases. These units are housed in a NEMA 4X rated plastic enclosure that will meet a wide variety of applications. The combo unit consists of a main unit (Carbon Monoxide only) with an LCD, LED status indication, 3 user configurable relays and a remote sensing unit (various gas types available) for installation at high or low elevations based on the density of the gas being detected. The main and remote unit gas concentrations levels are both displayed on the main unit's LCD.
