Zigbee Motion Sensor

User Manual

SNZB-04P is a Zigbee 3.0 protocol-based door/window sensor equipped with a tamper-proof feature. It senses the open and close status of doors and windows by detecting the proximity of the transmitter and magnet. This sensor seamlessly interacts with other smart devices to easily create various scenarios, such as automatically turning on lights when a door is opened, triggering audible and visual alarms in case of unauthorized entry, and sending app notifications to keep you informed.

1.Tear off the protective film of the 3M adhesive.
2.Try to align the mark line on the magnet with that on the transmitter during installation.
3.Install them in the opening and closing area separately(such as windows).

Make sure the installation gap is less than 20mm when the door or the window is closed.
