Smoke Alarms/CO Detectors

Ionization Smoke Alarm: Type of smoke detector that uses a small amount of radioactive material to make the air within a sensing chamber conduct. (5th edition Fire Essentials book.)

Photoelectric Smoke Alarm: Type of smoke detector that uses a small light source, either an incandescent bulb or a light emitting diode (LED), to detect smoke by shining light through the detector's chamber: smoke particles reflect the light into a light-sensitive device called a photocell. (5th edition Fire Essentials book.)

CO Detectors: Device that monitors for the presence of Carbon Monoxide to prevent Carbon Monoxide poisoning. Unit alarms if levels are above the manufacturer's recommendation.

The National Fire Prevention Association recommends that if one detector/alarm activates then all of the alarms/detectors should activate.

The Rootstown Fire Department suggests that you change your smoke alarm/CO detector batteries annually and test them monthly.
