Smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector itself.
Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery.
Why choose photoelectric alarms?
Photoelectric smoke alarms are much faster at detecting this dangerous situation than ionisation alarms. Studies have shown that photoelectric alarms typically
respond to smoky fires within about three to five minutes — when the level of smoke is still fairly low and escape is relatively easy. Most ionisation alarms
take much longer — up to 20 minutes or more — by which time there’s enough smoke to significantly reduce visibility, making escape much more difficult.
