The Waterbug single zone water leak detection system is designed to detect the ingress of water in sensitive areas where high value equipment, information, or materials are present. Waterbug is capable of working with a variety of detection devices, including sensor cables and probes.

When it detects the presence of water, the Waterbug will go into "alarm" status. There are 2 versions of the Waterbug: the standard Waterbug and the Waterbug+Plus. The standard Waterbug is a blind box with no local alarm outputs. It connects via a volt-free relay to the BMS. When a leak is detected, the relay changes over and the BMS will be alerted to the situation. The Waterbug+Plus has the same functionality as the standard Waterbug with the addition of a local audio and visual output on the alarm panel.

Typical Waterbug applications include archive rooms, communications rooms, computer rooms, electrical switch rooms, boiler houses, plant rooms, small data centers, and coffee/break rooms.

The Waterbug can use up to 2 sensors wired in parallel attached, allowing more than one area to be monitored simultaneously.
