About photoelectric alarms

Photoelectric smoke alarms, also known as optical or photo-optical, detect visible particles of combustion.

They respond to a wide range of fires, but are particularly responsive to smouldering fires and the dense smoke given off by foam-filled furnishings or overheated PVC wiring.

Advantages

  • Good for smouldering fire and dense smoke
  • Not as prone to cooking nuisance alarms
  • Contain no radioactive material
  • Suitable for general use.

Your protection against fire increases with the quality and type of smoke alarm that is installed. Research indicates that photoelectric smoke alarms are generally more effective across a wider range of fires experienced in homes.
