1 Beeping or chirping from a CO carbon monoxide detector alarm, a sound that is not continuous but sounds every few minutes, may indicate a dead or dying battery-replace the battery; if the alarm is in doubtful condition replace it.ere are some causes of Carbon Monoxide Detector alarms sounding: 1  The CO alarm has detected carbon monoxide in the building at a dangerous level. 2  The alarm may sound if there is a sudden surge of high concentrations of CO or it may sound if lower levels of CO have been present for a longer period.
You can test a carbon monoxide detector to ensure it can identify the level of carbon monoxide (CO) in the air, measured in parts per million (ppm). Pressing the 'Test' button on the detector will only tell you whether the device has adequate electrical power from an outlet or batteries.tep 3: Test Digital Readout CO Detectors with a Low Level CO Source. To confirm that a digital readout CO detector is detecting carbon monoxide, test it with a substance that will detect low levels of the gas, such as a lit cigarette or a lit incense wand.
