Structure and Installation
1) Fix the probe base JBF-VB4301B on the embedded box with two M4 screws.
2) Use a special electronic encoder to set the address (1-200) for the detector.
3) Adopt ZR-RVS-2×1.5mm2 twisted pair cable, and the two-wire bus in the loop connect to the terminals L1 and L2, regardless of polarity.
4) Mount the detector onto the base and tighten it clockwise. The installation should be done with gloves on to keep the detector clean.
