4.10 (Optional) Connecting a Point-Type Water Sensor

Context
This section describes how to connect a water sensor. A water detection cable can
also be connected.
A water sensor monitors resistance changes at terminals to determine whether
the floor is watery. When the terminals of a water sensor detect water or other
conductive liquid, resistance between the two terminals decreases. Keep water
sensors far away from water traps or floor drains.
Procedure
Step 1 Connect one end of the water sensor cable to the water sensor.
Step 2 Connect the other end of the water sensor cable to the signal terminals 1 and 2 of
X502 through the bottom of the cabinet.
