What Is an Optical Smoke Detector?
An optical smoke detector is a smoke detector that uses a light sensor to detect smoke. Inside the device, a chamber holds a light beam; when smoke particles enter and scatter the light onto the sensor, the alarm is triggered.
Optical detectors are especially effective at detecting the larger smoke particles produced by slow, smouldering fires - the type most common in homes.
The PhoneWatch Optical Smoke Detector is a smart optical detector: it is professionally installed and detects smoke, temperature changes and rapidly rising heat. It is also connected to PhoneWatch’s 24/7 monitoring as part of a complete alarm system.

Why a Smart Optical Smoke Detector Detects Fire Earlier
Unlike standalone smoke alarms that only alert occupants inside the property, PhoneWatch’s monitored smoke detector connects directly to a professional response team. This helps reduce emergency response times and ensures action can be taken even if the property is empty.
A fire can spread in minutes. PhoneWatch’s Optical Smoke Detector is professionally installed and connected to our 24/7 Monitoring Centre, helping ensure rapid response when smoke is detected, even if you’re not at home.
How Optical Smoke Detection Works
Optical smoke detection uses a sensing chamber with a light beam. When smoke enters the chamber, it scatters the light onto a sensor. Once smoke reaches a certain concentration, the alarm is triggered.
