The infographic above, courtesy of Spy Alarms, illustrates how the different smoke detectors pick up the smoke particles. As you can see, both detectors use a source and a sensor and, when the smoke prevents the sensor from being able to detect the radiation or light, the alarm is triggered. So, now you know … Meer weergeven Ionisation alarms are the more dated option out of the two, but that doesn’t mean they’re not relevant any more. As you learnt earlier, ionisation alarms rely on tiny particles of radiation to detect the presence of … Meer weergeven Optical smoke detectors, on the other hand, are a more modern (and slightly more expensive) alternative. They are less sensitive to fast burning fires, such as the quick fires that start in the kitchen. Because of … Meer weergeven Our professional fire alarm system installers will know the best type of smoke detectors for your home.

WebOptical smoke alarms, also known as photoelectric detectors, are less prone to false alarms than ionisation models and are slightly quicker at detecting slow smouldering fires that … WebThe optical ionization schemes are denoted by the amount of photons necessary to make the ion pair. For the first two Schemes 1 and 2, two photons (and processes) are involved. One photon excites the atom from the ground state to an intermediate state while the second photon ionizes the atom.
