The GB212 is a compact input signaling device with a pir motion sensor.
Thanks to the use of a motion sensor to trigger the sound signal, it can be used as an alarm or as an input signaling device.
In addition, we can use the sensor to ensure the safety of children - by installing sensors where they should not enter and informing us when they appear in the sensor's field of view. the pir sensor detects only movement of people and large animals, so there are no false alarms.
The parent unit has 52 melodies that can be selected freely and 4-step volume control.
