The Model WD-2-T tape style water detector uses a self-adhesive sensor tape with copper fiber electrodes and a durable netted cover for dependable detection of conductive liquids anywhere along the length of tape. The Model WD-2-T is ideal for HVAC and Building Automation System, BAS, applications. It includes a tape integrity self-check feature, which activates a trouble output if the tape is unplugged, broken, or cut. Alarm relays may be independently jumpered to energize or de-energize upon water or trouble detection.
