- Hand-in-hand wiring is highly recommended, yet star-topology or tree-topology is strongly deprecated
- RS-485 layout wire length shall not be longer than 300m, and 12 pcs of sensors is the maximum quantity layout in one circuit
- 4-pin shield wire or class 6 network wire is highly recommended for the layout
- Our sensor doesn't have terminal resistance. If there's an impedance matching problem in the RS-485 bus, we recommend connecting 2 pieces of 120Ω resistance in the terminal

When powered on, the sensor indicator will stay on for 15s for recognizing the application room size, after that sensor will enter a 10s flashing self-checking phase, after that, it will enter a 20s detection cycle. If presence is detected, the sensor will report absence. During initialization, the sensor will not detect a moving signal, and you can use the Merrytek WeChat mini program to adjust the detection area, hold time, daylight sensor, etc, parameters.
Embedded mounting installation
- Trepanning a 50-55mm hole
- Securely wire the cable into the terminal
- Press the program button
- Put the spring clip into the hole and fasten it well
- Ensure the sensor is firmly installed

Detection Area: 4m | Hold Time: 30S | Indicator Light: open | Sensitivity: medium sensitivity
