The IO HVAC CONTROLS Q5C-CO-250P-0-A is a carbon monoxide (CO) sensor designed for use in HVAC and building automation applications. It detects CO concentrations in occupied spaces and transmits that data to a building control system or air handling unit, enabling ventilation adjustments or alarm responses. The unit measures 3.5 inches wide by 2.625 inches high by 5.9 inches deep and weighs 1 pound, making it a compact wall-mount device suited for commercial and residential installations. HVAC technicians and building automation specialists are the primary installers.
This CO sensor is appropriate for use in commercial buildings, schools, parking structures, and residential applications where carbon monoxide monitoring is required by code or design specification. It integrates into HVAC control systems to support demand-controlled ventilation or safety shutoff sequences. The compact form factor allows installation in standard wall locations near air return pathways or within occupied zones where CO accumulation is a concern.
Designed as an OEM-style CO sensing device for use with compatible HVAC control systems and building automation controllers that accept a carbon monoxide sensor input.
Installation should be performed by a licensed HVAC technician or building automation controls specialist. Power down the control system before wiring the sensor to avoid damage to the device or control board. Follow all applicable local codes and manufacturer wiring diagrams when connecting signal and power leads. Mount the sensor in the occupied zone at the appropriate height per local code requirements for CO detection.
