An optical smoke detector is one part of a fire alarm system.

It’s a device that raises an alarm when it senses smoke – as shown in this infographic.

How Does An Optical Smoke Detector Work?

The infographic shows how a build up of smoke particles can obstruct the infrared light inside the alarm casing. This means it can’t be seen by the sensor and causes the alarm to activate.

The most common alternative to an optical alarm is an ionisation smoke detector that works in a similar way. It has a source and a sensor, when the smoke particles get between them, it changes the signal and activates the alarm

Optical smoke detectors are the more modern choice and are generally considered to be the most reliable option.

Usually you’d have a few of these detectors as part of a wider home or business fire alarm system, though they can also be placed individually around a property. It’s always better to get a professional to install your optical smoke detectors as they will know how many your property requires and the optimum positioning for them for maximum security.

Optical Smoke Detectors As Part Of Your Security System

As home and business owners are becoming more security conscious, it’s now common for these fire alarm alarm systems to be integrated with security systems.

This integration is more reliable than standalone optical smoke detectors and is fitted by our experience engineers.
