The GB-212 device is an input indicator consisting of a wireless doorbell and a wireless PIR motion detector. Detection of motion by the PIR sensor triggers a bell sound signal, which can be used as entry information or an alarm signal.
The product is used in service points, shops, in companies and at home. It can be used to ensure the safety of children by installing the detector in a place where children should not be. The PIR detector only detects the movement of people and large animals, so there are no false alarms.
The doorbell (receiver) can work with a maximum of 8 motion detectors (transmitters).
