1.Fix the base with two tapping screws,and then connect loop to terminals(polarity-insensitive).After the base is fixed firmly,rotate the bottom of detector and base clockwise,and then the detector will be fitted to the base.
2.Wiring instructions:RVS twisted pair with cross-sectional area 1.0mm2 should be selected for the second bus of the detector,which should be laid through metal pipe or flame retardant pipe.The length of the connecting wire should be limited to the single bus resistances 20Q,otherwise the wire diameter should be increased.
