INSTALLATION
Place SP-12 on a flat surface where
1.
water accumulation or water leakage
can possibly occur. (Ex: air-conditioner
water tray, pantry, flood prone rooms)
Connect the red (+) and black (-) wires
2.
to the power supply. It depends on the
color of the PCB if it will be connected
to a 12VDC or 24VDC supply
The white and yellow wire are the relay
3.
alarm outputs. You can connect it as
inputs in EMS devices such as Picobox
REX and FMGuard or other alarm
detection systems.
