Scope of delivery
The GX-D500 CO₂ alarm is a professional warning device with fixed alarm thresholds of 1.5% CO₂ for pre-alarm and 3.0% CO₂ for main alarm.
The alarm threshold, which is clearly perceptible both audibly and visually, was deliberately set high to prevent false alarms from poor indoor air quality caused by human exhaled CO₂, while still allowing defects in technical systems to be detected immediately and reliably. The exact values are based on the specifications of the technical guidelines for beverage dispensing systems in the hospitality industry.
In the event of an alarm, a potential-free changeover relay (230 V~ / 5 A) switches, which can, for example, activate forced ventilation or close magnetic shut-off valves. Another potential-free changeover relay (60 V= / 5 A) switches in the event of technical faults detected by the device itself and thus informs, for example, the building management system.
In monitoring mode, both relays are energized and de-energized in the event of an alarm/fault.
A large, illuminated 2x16-character display continuously provides information about the currently measured CO₂ level and, when scrolled through using the SERVICE button, provides additional status messages. This includes monitoring temperatures inside the device, counting alarms, displaying an error code in the event of technical malfunctions, and recording the CO₂ concentration in ppm during the last alarm.
With the optionally available USB calibration adapter cable (item 200340), the user can perform a zero point calibration of the sensor regularly or as needed, as every sensor is subject to natural drift. The preset range of the warning thresholds is always maintained and can only be changed at the factory.
