Although the risk of household fires increases in the winter, so too does the risk of false alarms.Most smoke detectors use either a photoelectric sensor, which reacts when light smoke blocks, or a sensor of ionization that detects changes in the power of the air. Alarms can operate on battery or electric power.
Types and operation of smoke detectors
When designing a fire detection system should provide for a set of equipment which is able to detect and report the presence inside of a building elements such as smoke, flames and high temperatures.These electronic devices detect the presence of fire based on physical phenomena associated with the development of the fire itself and must therefore be placed according to very precise rules, better indicated in the Uni 9795, where you can find the standard indications related to positioning of the sensors and devices.
