The OSD 23 optical smoke sensor is designed to detect visible smoke which develops during the early stages of fire when material is smouldering, well before the appearance of open flames and a distinct increase in temperature.

The sensor is designed for closed interiors which have no smoke, dust or condensation under normal conditions. However, thanks to the introduction of an analogue system for compensation changes in the environment, it has increased protection against changes in pressure, temperature and condensation. One sensor is sufficient for a room of up to 40 m2.
