Other filters move air without a fan, instead using electrostatic charges to attract ions in the air. Negatively charged plates inside the filter attract and hold particles (most of which have positive charge), but also generate ozone (a molecular form of oxygen containing three oxygen atoms—O3—that is considered a pollutant). So some models have a guard that converts any ozone generated back into harmless oxygen molecules, which have two atoms of oxygen (O2). Another feature of some air filters is an ultraviolet lamp that kills airborne viruses and bacteria.
H O W I T WO R K S Alarms can be tripped manually by pulling a lever, or automatically by one of several types of smoke sensors. Only building personnel can reset manual levers once they've been pulled. Leaving the levers in the "pulled" position shows fire teams which pull station was activated. The photo shows a manual fire alarm. Sensors can detect smoke, heat, or the flow of water through an activated sprinkler head. If a fire sprinkler detects heat and turns on, the flow of water through the pipes can alert the alarm system that a fire is present.
Valves throughout the system allow for individual radiators to be cut off from the flow of hot water if a room doesn't need to be heated. Some systems have thermostats in each room that control the valves to adjust the temperature. Return pipes carry the water that has passed through radiators back to the boiler for reheating. Hot water radiator systems are good at maintaining a steady temperature in a large building but are slow to respond if you want to change the temperature. I N TE R E S T I N G FAC TS Although the Romans circulated warm water through houses for heating, central heating did not appear again until the eighteenth century in France.
