The Benefits of an optical smoke alarm

Unlike a regular smoke alarm, an Optical Smoke Alarm is designed around the Light-Scatter Principle – using beams of light every 10 seconds as a means of checking for smoke particles in the air.

As smoke particles enter the smoke alarm, light is then able to be reflected where it is usually unable – this results in light hitting a receptor, triggering the alarm.

See diagrams of this taking place through Safelincs. 

The main benefit of an optical smoke alarm, in comparison to a regular one, is – due to the nature of smoke particles needing to be present for the alarm to go off, the alarm as a result is much less likely to trigger a false positive. Whenever the alarm goes off, you can be certain that a fire event is occurring.

Another benefit of an optical smoke alarm, over a regular alarm, is the manner of interconnectivity that can be brought.

Alarms acting as part of a network, enable much more information to be spread regarding the start of the fire, the time a fire started and – most importantly – the direction the fire is spreading in.

Information such as this can allow individuals to quickly escape dangerous situations and avoid being trapped during building fires and the like.
