The **Series WD3 Water Leak Detectors** protect equipment from water damage by detecting the presence of water. Model WD3-BP-D1-A is battery powered, all others require AC or DC supply voltages. 

## **BENEFITS/FEATURES** 

• Audible and visual alerts provide local indication of the alarm condition and internal switch will give remote indication or control to prevent further buildup of water 

- Sensing height can be adjusted as low as 1/32˝ (0.79 mm) using the included adjustable mounting bracket 

- Mounting bracket can attach to any flat surface by either using the attached adhesive strips or mounting screws for easy installation 

## **APPLICATIONS** 

- AHU drip pans 

- Radiant floors 

- Data centers 

- Sump pumps 

- Drains
