Touch Spot Set （TSS-1）
 
Additional detector can be added to the WD-1 by using the TSS-1 / T-splitter and water detector (sensor) set. It comes with a T-splitter and an additional water detector in order to have multiple points to detect water by using a single WD-1 module. This is useful when trying to monitor for water spills or floods, or to monitor water run-off at multiple locations.
