An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [3] or restricted for use by the height of the building.
In large open areas such as atria and auditoriums, optical beam or projected-beam smoke detectors are used instead of a chamber within the unit: a wall-mounted unit emits a beam of infrared or ultraviolet light which is either received and processed by a separate device or reflected to the receiver by a reflector. In some types, particularly ...
In the 2000’s, System Sensor introduced the i3 line of smoke detectors, which came in 2 and 4 wire models. These devices have a feature which they will poll with the fire alarm panel when the sensor is dirty, causing a trouble condition on the panel.
Whole-home integration: Choosing smoke detectors that are integrated into your whole home system can be more effective than standalone smoke detectors, as they can alert other systems to change ...
