Testing the Heat Detector
Because heat detectors are designed for a one-time use, it is not recommended that you test
them yourself.. If you have concerns about the readiness of the heat detector, please refer to the
How They Work
Smoke Detectors
There are three common styles of Smoke Detectors:
•
Ionization:
Detects fast, flaming fires caused by chemicals, petroleum based products,
paper and wood. It is equipped with two metal plates and a small amount of radioactive
material to ionize air. When smoke passes through the device, it interrupts the ionization
and triggers the alarm.
•
Photoelectric:
Detects visible smoke, slow burning, smoldering fires caused by drapes,
clothes, paper and wood. It operates with a light beam inside; smoke particles break the
light beam and triggers the alarm.
•
Dual:
Includes both Ionization and Photoelectric sensors.
Smoke detectors should be mounted on a ceiling or high on the wall. The
recommends that there be at least one smoke detector on each floor,
including outside sleeping areas, in every bedroom and in the basement.
