Eelectron SM03E03ACC PlugIn Sensor for PD00ExxKNX CO2, VOC, temperature – white

SKU: SM03E03ACC
✗ UL Listed
This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The Eelectron SM03E03ACC is a plug-in indoor-air-quality sensor in white for the Eelectron presence detector range, with a true CO2 sensor (400–2000 ppm) plus VOC and temperature sensing. Clipped onto a PD00E02KNX Multi, PD00E03KNX Space, PD00E20KNX Wide Range or PD00E21KNX Corridor detector it turns the ceiling device into a complete demand-controlled-ventilation sensor for classrooms, meeting rooms, hotel rooms and open offices, with no extra bus device.

The module is powered and read through the host’s smart-sensor input and its front LED can be set to one of 4 modes to show CO2 bands (off ≤ 700 ppm, slow blink to 1000 ppm, fast blink to 1600 ppm, steady above) as a visible ventilation prompt for occupants. The VOC channel reports TVOC and needs approx. 96 hours to stabilise. Mount the sensor-plus-plug-in pair with the PD00E07ACC double squared ring, or in a PD00E00ACC surface enclosure. The black version is SM03E03ACC-3; the lighter SM03E02ACC offers VOC with eCO2 estimation only.
