FIRE PROTECTION SYSTEMS

Photoelectric detectors are better suited than ionization detectors for locations with high humidity. Air velocity also may affect smoke detector operation. A special type of photoelectric smoke detector is the projected-beam detector. Here the operating principle is the same as a light-obscuration-

sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ion-ization alarms. Home fires develop in different ways and are often unpredict-able. For maximum protection, Kidde recommends that both Ionization and Photoelectric alarms be installed.
