The detector recognizes motion and sends the first alarm immediately, but next alarms until disarming are transmitted no more than once in 5
seconds.
If a motion is detected before the system is armed, the detector will be armed not immediately, but during the next
polling by the hub.

An obstacle in front of both lenses (an object on the height of the detector and at a distance of up to 20 cm in front of
it)
• An obstacle in front of any of the lenses (an object at a distance of up to 10 cm in front of one of the lenses)
• Painting or pasting any of the lenses with an opaque substance
