SYSTEM OVERVIEW

WATER

WATER

WATER

WATER

The WB-800 is a completely electronic water detector which is designed to detect only
nonflammable conductive liquids (distilled and deionized water cannot be detected).
The WB-800 is designed with the control console mounted on the wall and the remote
probes placed in locations where water seepage is most probable.

Option # 2 Surface Mounting with Mounting Box

In areas where no hollow interior walls are available, the included standard 3-gang
surface mounting box can be secured to any wall. The installed profile of the WB-800
with this option is about 2½“ out from the wall.

INSTALLATION - POWER AND PROBE CONNECTIONS

The unit includes four (4) supervised surface probes (W-S-S). In addition to detecting
water with this probe, the unit will alarm when the supervised probe line becomes
disconnected.

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 (Figure 1). The relay
output is non-latching, but will remain closed until the moisture bridge between the
two contacts is broken. As sensitive as the WB-800 is, it will not alarm due to high
humidity or condensation. The WB-800 is ideal for use around homes, office buildings,
computer rooms, boats, etc. Additional features include:

• Accepts 12V, 24V AC/DC power input

• Eight alarm LED indicators to identify the probe zone in alarm.

• Supervised probe line option. Unit will alarm on open probe condition and an
indicator will light. Up to 8 supervised probes per console (W-S-S or W-UC-S).
Probe lines up to 500ft.

• One “Form C” SPDT Relay for alarm output.

• Built in audible alarm and remote buzzer output with silence feature (adjustable
3 seconds to 150 minutes)

Four Probe Contacts

Mount the probe to

ensure these four
stainless steel contacts
are against the surface

to be monitored.

Step 1 - Power Connections

The WB-800 will operate on 12V, 24V AC/DC. Refer to Figure 3 for proper connections.

Note: Before making wire connections, set jumper “JP3” to either 12V or 24V
depending on your power supply output.

Connect your power input to two of the three positions on the terminal block.
Regardless of your voltage input, connect the negative side to “V-“. If your supply is
12V AC/DC or 24VAC, connect the positive side to the position marked “12VAC/DC,
24VDC”. If using 24VAC input, connect to the 24VAC input.

When the power is applied, the green ON power indicator should be on.

Note: If the built-in buzzer sounds, it can be disabled by moving jumper “JP2” to the
OFF position. If desired, toward the end of installation, it can be reactivated.

Important: If you are not using Winland’s 12VDCT power supply accessory with this
product, ensure that your power supply does not have a connection to earth ground.
If the WB-800’s power is connected to earth ground, it’s possible that the sensor will
fail to alarm when wet due to the possibility of a ground loop that may exist from the
sensor terminals through the earth back to the power supply. This will change the
system’s voltage reference, which will, in turn, change its trip point. In all cases, test
the system to ensure it will trip as expected when water is encountered.

Step 2 - Probe Connections

ALARM NO ALARM

CONSOLE MOUNTING CONSIDERATIONS

Select A Site For The Console

Probe cable lengths and power source locations should be considered. Maximum cable
length for the water probes is 500 ft.

Option #1 Surface Mounting Without Mounting Box

It is possible to install the console on a soft wall (sheet rock, panel, etc.) without the
use of a mounting box. This is the fastest mounting method and it gives the control
console a nice looking low profile. In selecting a site to mount the console, keep in
mind that it must be placed in a secure, dry location with an ambient temperature
of 32˚ to 130˚F (0˚ to 54˚C). For this option, drill a ½” diameter hole(s) in the wall
which will be opposite the wiring terminal strip on the console. This hole will provide
access for all wiring. Next, carefully mark the location of the four corner screw holes
on the console. Then drive four wall anchors into the proper locations and complete by
attaching the console to the wall.

Option 1 - Supervised Probe Mode

The unit includes four supervised surface probes (W-S-S). Additional probes (surface
[W-S-S] or under carpet [W-UC-S]) may be purchased separately.

With no probes attached to unit and with the 8 position DIP switch settings (SW1)
in the down position, zone alarm indicators 1-8 and the probe line alarm indicator
should be on. When the probe line alarm indicator is on, it shows there is an open
probe line. When the zone alarm indicator is on, it shows that a specific zone is in
alarm (either water detected or open probe line).

For zones that are not planned to be used, the supervised mode can be disabled
(i.e. open probe line alarm turned off) by pushing the DIP switches up for the
corresponding zones.

The WB-800 has two terminal blocks (TB1 and TB2) that are the locations for
connecting the probe inputs. There is no polarity to the probes. The probes are
included with 15’ (4.5 m) of cable. The probe cables can be increased to 500’ (152.4
m) with additional cable (22-18 AWG twisted pair, is recommended). Be sure that all
splices are moisture proof.

Note: For probe placement and mounting, see Figures 1 and 2.

Caution: If a supervised probe is used, and the zone DIP switch is inadvertently left

in the “up” position (supervised mode disabled) the probe will still be operational to
detect water, however, the open probe line alarm will not be operational. Verify the

DIP switch is in the “down” position for zones being used.
