The NUMENS 400-003 is a non-addressable carbon monoxide (CO) gas detector designed for use with 4-wire fire detection systems. It features advanced electronics and a semiconductor sensor for early CO detection and high immunity to false alarms.

Operating at 12–24V DC, the device includes an SPST relay output (N/O or N/C) and an auto-reset function when CO levels drop below the threshold. An internal sounder ≥ 85 dB alerts occupants, and built-in fault diagnostics provide a short audible signal every 30 seconds if an internal error occurs.

The 400-003 model is compliant with EN 50291 (for residential CO detectors) and UL 2075 (for gas and vapor detectors), ensuring high reliability in both residential and commercial settings. The detector is easy to install, with a low-profile design requiring no programming. Dimensions: 99 mm diameter, 45 mm height. Protection rating: IP42. Operating temperature: -10°C to +40°C.
