Hydrant Button
The hydrant button and JBF series detectors are used together in the two-bus fire alarm system with the JB series control panels. Inside the fire hydrant button is a set of passive contacts to connect to the fire pump in the field.
Application design is in accordance with national standards GB 50116 "Fire automatic alarm system design specification."
Suitable for hotel rooms, office buildings, libraries, theaters, postal buildings and other plac

Product Features

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) Put on the front cover after checking the wiring. 

● Terminals 1 and 2 connect bus L1 and L2, and polarity is reversible.
● Terminals 7 and 8 are normally open contacts. They close when the hydrant button is pressed.

Conduct alarm test regularly, every six months recommended.
