Macurco CX-6-NO2 Nitrogen Dioxide NO2 Detector & Controller w/ Replaceable Sensor, Gray Housing, Voltage 12-24VAC / 12-32VDC, UL2075 Listed

The Macurco CX‑6‑NO₂ is a low‑voltage, fixed Nitrogen‑Dioxide gas detector / controller engineered for vehicle‑exhaust environments—parking garages, loading docks, fleet maintenance bays and similar high‑traffic spaces. Running on 12–24 VAC or 12–32 VDC, it samples 0‑20 ppm NO₂ in real time, shows readings on a bright LED, and backs them with an 85 dB internal buzzer and selectable alarm relay. A 5 A SPDT fan relay plus 4‑20 mA output automate exhaust fans, BAS links or fire/security panels, while fail‑safe diagnostics activate relays if a fault is detected. The UL 2075‑listed unit offers a 4‑5 year field‑replaceable sensor with end‑of‑life alert, digital display, and covering up to 7,500 ft² per device. Pre‑calibrated and usable stand‑alone or networked with Macurco panels, the CX‑6‑NO₂ delivers code‑compliant, cost‑effective NO₂ mitigation for commercial facilities.
