A device designed to measure carbon monoxide (CO) levels requires periodic evaluation to ensure proper functionality. This assessment process typically involves initiating a self-test function built into the unit, or employing an external source of carbon monoxide to trigger an alarm response. The self-test verifies the detector’s internal circuitry and alarm system. A response to a known concentration of CO from an external source provides more comprehensive verification of the sensor’s sensitivity and accuracy.
Regular verification of these devices is paramount for occupant safety within residential and commercial buildings. Functioning units provide crucial early warnings of elevated CO concentrations, potentially preventing carbon monoxide poisoning. These evaluations have become increasingly significant given the widespread use of fuel-burning appliances and the dangers of improperly ventilated spaces. Consistent testing reduces the risk of malfunction and ensures continuous protection.
