"Approved carbon monoxide alarm" and "alarm" have the meaning ascribed to those terms in the Carbon Monoxide Alarm Detector Act.
"Carbon monoxide detector" and "detector" mean a device having a sensor that responds to carbon monoxide gas and that is connected to an alarm control unit and approved in accordance with rules adopted by the State Fire Marshal.
Alarms or detectors must be located within 20 feet of a carbon monoxide emitting device. Alarms or detectors must be in operating condition and be inspected annually. A school is exempt from the requirements of this Section if it does not have or is not close to any sources of carbon monoxide. A school must require plans, protocols, and procedures in response to the activation of a carbon monoxide alarm or carbon monoxide detection system.
