The hydrant button and JB series detectors are used together in the two-bus fire alarm system with the Jade Bird series control panels. It is used to manually send alarm, start fire pump and show the operation state of the fire pump when fire occurs in public places. Application design is in accordance with national standards GB 50116 "Fire automatic alarm system design specification." It is suitable for industrial and civil places where combustible and explosive gases existing.

Structure and Dimensions
1) After wiring construction, the base is secured to the wall by pre-buried box or using expansion bolts. The pitch of holes distance is 60mm (compatible with 50mm mounting holes distance).
2) The hydrant button adopts RVS2×1.5mm2 twisted pair connecting to the control panel.
3) Write address (1-200) to the manual call point using electronic encoder.
4) The detection bus L1, L2 connect to terminal 1 and terminal 2.
5) There are knock-down holes in the left and right positions of the base (waterproof connector is required if the hole is used for entering cable). In normal installation, it is recommended to enter the cable from the bottom inlet hole, which can be without special waterproof sealing, easy to operate and convenient.
6) Fire hydrant button is recommended to be installed after wiring inspection and before commissioning to prevent losses caused by improper installation.
7) After checking the wiring, insert the fire hydrant button to its base and use tapping screws to secure them together. 
● Installation shall be carried out in accordance with the relevant provisions of GB 3836.15-2010 Electrical apparatus for explosive gas atmospheres - Part 15: Electrical installations in hazardous areas (other than mines) and by our company's professionals.
● The safety barrier shall obtain an explosion-proof certificate and its installation shall be carried out in accordance with the requirements of its instructions.
