| | The suitable fire detectives are following: in homes: | | | 1.Modern smoke sensors or Gadgets: | | | These smoke sensors or gadgets may be permanently installed in buildings for the early detection of fire. | | | The ionization-chamber type smoke detector consists of an open sensing chamber in which the air is ionized by radiation from a radioactive source. | | | A small electrical current passes between two electrodes. Smoke entering the chamber causes a reduction in the current, which operates an electronic relay in circuit to give an alarm. | | | 2.Optical or photocell sensors: | | | Optical or photocell type of sensors has a beam of light scattered and absorbed by the smoke particles entering the detector. | | | This produces a change in light intensity which may increase or decrease depending on whether scattered or transmitted light is measured. | | | This change causes the electrical output from the light-sensitive photocell to vary and activates the alarm system. | | | | Note: Smoke detectors are efficient only if the general level of smoke or dust particles in the atmosphere is not high. Each sensor can cover a specific area. | | | | | | | | |
