GLiT GD04 Recessed Ceiling Motion Wired Sensor Security System

GD04 is a Recessed ceiling mount infrared motion sensor. The highly sensitive pyro-sensor gives it coverage of 360 degree at the aperture angle of 120 degree with the detection range of 6 meters. It is most suitable for medium sized covered areas. It has highly sensitive pyro-sensor operating as the heart of its system. It detects heat radiated from a body. Segmented lenses divide the whole detection area into passive and active zones. When any warm object like human body moves between the zones, it is detected as a change in voltage by the pyro-sensor. When it detects such movement, it triggers the switching mechanism to operate the connected load. As the pyro-sensor operates by detecting change in the temperature, the ambient temperature plays important role in working of this motion sensor. Maximum detection range mentioned in the technical specifications is measured at the ambient temperature of 25 degree C. Detection range might change with the change in ambient temperature.
