NTRODUCTION
Thank you for your purchase of the Winland WaterBug model WB350. The WaterBug is completely electronic and is designed
to detect water only (distilled and deionized water cannot be detected). For proper operation this unit must be used in
conjunction with an alarm system, wireless transmitter, etc. It is designed so the control console mounts on a wall or other
flat vertical surface and the remote probes are placed in the locations where water leakage is most probable. Up to six
remote probes may be connected to one control console. A film of moisture forming a bridge between the two metallic
contacts on any remote probe is all that is needed for the unit to signal an alarm condition.
The output on the WB350 is non-latching, but will remain closed until the moisture bridge is broken. As sensitive as the
WaterBug® is, it will not alarm due to high humidity or condensation. The WaterBug® is ideal for use in homes, offices,
computer rooms, boats, etc. Several consoles may be wired together to monitor an entire complex.
LOW BATTERY INDICATION:
The WB350 will trip the open collector output and give an audible warning if battery voltage
runs low.

NSTALLATION
Locate the area where the WaterBug® console is to be mounted. Mark
the position of the screw hole on the mounting surface. Drive the
mounting screw into the wall allowing 3/16” between the screw head
and the wall. Engage the key slot on the back of the console and the
screw head and press down.
Multiple probes must be hooked up in parallel to terminals S and S. See
Figure 1. The remote surface probes may be mounted securely to the
floor or a wall. See Figure 2 and Figure 3.
Mounting the probe(s) to a vertical surface like a wall enables you to
monitor an area for rising water levels. This is useful in basement sump
pumps and other types of water storage and drainage systems.
Note:
WB350 is equipped with an onboard buzzer for local
annunciation and low battery warning.

ONNECTIONS
The WB350 is powered by one 9-volt alkaline battery. To install the
battery, loosen and remove the four corner screws. Insert the new
battery and retighten the four corner screws. The WB350 can be used
in conjunction with virtually any type of wireless transmitter if any
one of the remote probes detects water. When connecting the unit to a
wireless transmitter, wire the N.O. terminal and C terminals to the input
of the wireless transmitter. If your initial wiring activates the wireless
transmitter when no moisture is present, reverse the leads on N.O. and
C on the unit.
