Winland WaterBug WB200 — Wiring Diagram Reference

Wiring diagram reference for the Winland WaterBug WB200 water/leak detection controller, showing how to connect it to a security panel using Normally Open wiring with six unsupervised surface sensors.

Wiring Configuration Shown

This illustration depicts a specific installation scenario for the WB200:

• 12V power pulled from the security panel
• Normally Open (N.O.) wiring configuration
• 6 unsupervised surface sensors (W-S-U) connected in parallel to the WB200's "S, S" terminals
• External alarm notification — the manufacturer recommends the BZ-1 bell/buzzer, wired to the C/NO terminals

Note: Supervised sensors (W-S-S) do not connect to this device in this configuration.

WB200 Terminal Strip

The WB200 controller board's terminal strip: V+, GND, S, S, C, NO, NC

• V+ / GND — 12V power input (from security panel AUX+/AUX-)
• S, S — sensor terminals (unsupervised surface sensors wired in parallel)
• C, NO, NC — relay output terminals for alarm signal/notification device, configurable for Normally Open or Normally Closed operation

Wiring Notes

• The WaterBug sensors are not polarity sensitive — they can be wired without regard to lead orientation.
• The security panel side of the diagram shows a typical alarm panel terminal strip including zone inputs (Z1–Z8), PGM outputs, AUX+/AUX-, and bell terminals — match to your specific panel's equivalent terminals.
• The alarm/signal wire from the WB200 routes back to a zone input (e.g. Z1) on the security panel, configured for Normally Open operation.
