What is smoke detector sensor ?

Smoke Alarms: Smoke alarms will detect most fires more rapidly than heat detectors. There are currently three types of smoke alarms on the market: ionization, photoelectric and combination ionization/photoelectric. An ionization smoke alarm contains a small amount of radioactive material.


  • Good for soldering fire and dense smoke.
  • Not as prone to cooking nuisance alarms as ionization alarms.
  • Contain no radioactive material.
  • Suitable for general use.
  • Carbon monoxide alarms are commonly used for the detection of fire in the home.
  • Very good with fast flaming fires with little visible smoke.
