Installation and wiring:
的电缆作为系统用线。 Loosen the fixing screw of the detector housing, open the flameproof cavity, and remove the test wire. Use a cable with a diameter of about 8mm as the system wire.
电源线从一侧进线口串入，接在线路板的输入端子 D 上（无极性）； K 为常开无源触点， B 为常闭无源触点。 Connect the DC24V power cable from the cable inlet on one side, and connect it to the input terminal D of the circuit board (no polarity); K is normally open passive contact, and B is normally closed passive contact. 3 接线图。 See wiring diagram in Figure 3 .
