Step 2 Route the signal cable through the signal cable hole at the bottom of the electric
control box.
Step 3 Connect the signal cable to X502 terminals 1 and 2.
● If a water sensor (rope-type) is to be connected, connect the signal cable to
terminals X201 and X202.
● When installing a water sensor (rope-type), avoid direct contact with metal.
Otherwise, false alarms may be generated. You are advised to use a winding
pipe to wrap the water detection cable. A φ20 mm pipe is recommended.
● Do not use metal fasteners to bind the water detection cable or bind it to a
metal pole. Otherwise, false alarms may be generated.
● Do not install the water detection cable in an area prone to dust accumulation
and long-term high humidity. Otherwise, false alarms may be generated.
● Do not lay out the water detection cable in an area prone to rainwater or water
vapor. Otherwise, false alarms may be generated.
