- Hand-in-hand wiring is highly recommended, yet star-topology or tree-topology is strongly deprecated
- When there's more than 1pc sensor in a line, you shall consider that all equipment current consumption shall not surpass your driver's loading capacity

When powered on, the sensor indicator will turn off after flashing for 10 seconds and will enter a 20S detection cycle. If presence is detected, the sensor will report presence and enter hold time calculation; if absence is detected, then the sensor will report absence. During initialization, the sensor will not detect a moving signal, and you can use our MH18 remote to adjust 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
