The Xevox 360° is a motion sensor with one PIR sensor. It reacts to heat movement and reports it to the alarm panel. Installed on the ceiling, this sensor monitors the whole room. With a detection range of 360°, these sensors have the complete room under control. The aperture angle of the lens is 110°. For example: If the Xevox 360° is installed at a height of 4 meters, it monitors a cone-shaped space with a diameter of 13 meters at ground level. At 1.2 meters above the ground, the diameter of the monitored area is 8 meters. It is particularly suitable for monitoring large, underground corridors. The optimum installation location of the Xevox 360° is the center of the ceiling. The intruder's possible direction of movement should be at right-angles to the sensor. Do not install the sensor near to sources of heat. By means of a jumper, you can change the sensitivity of the Xevox 360° motion sensor. This way you can define the number of pulses that have to be detected before the sensor opens the alarm relay.
