WNWB800 Waterbug - Description

The WaterBug WB800 Model is an eight zone water detection system, ideal for monitoring several areas with one unit, or a large area. As many as eight supervised sensor probes can be run up to 500 feet away (or 16 non-supervised sensors). Each sensor probe has two contacts. When a film of water forms a bridge between these contacts, the unit senses this goes into alarm. Condensation or high humidity will not send the unit into alarm . Four standard surface sensors are included with the unit.

Sensors come with 12' of wire.

The WaterBug model WB-800 operates on 12 or 24 Volt AC/DC and has a form C relay output that can be connected to alarm panels, bells, dialers, etc. This unit also includes internal alarm buzzer with silencing switch and eight LED's on the console so you can identify which sensor is in alarm.
