Step 3 - Alarm Relay Connections
The WB800 includes one Form C (SPDT) Relay. This relay is activated when power is applied
and the unit is not in water detect or open sensor mode. This feature provides power-on
supervision in case of power loss.
Note:
When power is applied and unit is not in alarm, a short exists between “NC” and “C”,
and an open exists between “NO” and “C”.
Step 4 - Installation- Audible Alarm and Silence Features
The WB800 has a built-in audible alarm which will sound on an alarm condition. An audible
silence feature is included that will disable the buzzer for a time period that can be set
from 3 seconds to 150 minutes. This feature is important in installations where a constantly
sounding alarm might disrupt business. It allows the audible alarm to be suspended while
you wait for the water to be cleared from the affected sensor. Note: During this time, the
alarm indicators and the relay outputs will remain in alarm condition as long as unit is still
in an alarm condition.
Note:
Jumper “JP2” can be set to enable or disable the built-in buzzer.
Step 5 - Optional Remote Buzzer Connection
The WB800 is capable of driving an external 12VDC buzzer (PN BZ-1). The buzzer is
connected to the terminal block as per Figure 2. As with the built-in buzzer, the remote
buzzer can be temporarily disabled by the audible silence feature.
Step 6 - Setting the Audible Silence Timer
The built-in audible silence timer provides an external means of silencing the audible alarm
for a user selectable period (3 seconds to 150 minutes). Set jumper “JP1” to seconds or
minutes. Adjust “P1” to the number of seconds or minutes desired.
Note:
If a great amount of accuracy is required in setting the number of minutes, the
jumper should first be placed in the seconds mode and then force the unit to alarm, the
number of seconds that the audible alarm was silenced corresponds to the number of
minutes. When satisfied with setting, place JP1 back to minutes position.
To insure proper operation, test unit weekly.
Caution:
Use only the BZ-1 buzzer due to the units extremely low
current draw. Using another buzzer may affect the performance of
the WB800.

Step 1 - Power Connections
The WB800 will operate on 12V, 24V AC/DC. Refer to Figure 2 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.
Step 2 - Sensor Connections
Option 1 - Supervised Sensor Mode
The unit includes four standard supervised sensors (PN W-S-S). Additional sensors may
be ordered separately.
With no sensors attached to unit and with the 8 position DIP switch settings (SW1)
in the down position, zone alarm indicators 1-8 and the sensor line alarm indicator
should be on. When the sensor line alarm indicator is on, it shows that there is an open
sensor line. When the zone alarm indicator is on, it shows that a specific zone is in
alarm (either water detect or open sensor line).
For zones that are not planned to be used, the supervised mode can be disabled
(i.e. open sensor line alarm turned off) by pushing the DIP switches up for the
corresponding zones.
The WB800 has two terminal blocks (TB1 and TB2) that are the locations for connecting
the sensor inputs. There is no polarity to the sensors. The sensors are included with 15
feet of cable. The sensor lines can be increased to 500’ (152.4 m) with additional cable
(22 AWG twisted pair is recommended). Be sure that any splices are moisture proof.
Note:
For mounting of sensors, see the sensor mounting sheet included with the
sensor.
Option 2 - Unsupervised Sensor Mode
The WB800 can also be used with the unsupervised sensors (PN W-S-U) and the
unsupervised under carpet sensors (PN W-UC-U). These sensors are used with
Winland models WB200 and WB350. With this type of sensor, up to two sensors can be
connected per zone. However the sensor lines are not supervised (i.e. break in sensor
lines will not cause an alarm). To use this type of sensor the DIP switch zones must be
pushed to the “up” position to disable the supervised sensor mode.
Caution:
Above method is only advised if the WB800 is used to replace an existing
model such as the WB200 where the existing sensors are planned to be used or more
than eight sensors are required to be connected to a console. To take maximum
advantage of the WB800, supervised sensors are recommended.
Monitoring the absence of water:
It is not recommended that the WB800 be used for this application. The WB200 is
recommended for this type of application.
Caution:
If a supervised sensor is used, and the zone DIP switch is
left in the “up” position (supervised mode disabled) the sensor will still
be operational to detect water, however, the open sensor line alarm
will not be operational, verify that the DIP switch is in the “down”
position for zones being used.
Important:
It is recommended on completion of installation
the sensor line be disconnected from the terminal block for each
zone being used to verify that the sensor line and zone indicators
light (supervised sensors only). The unit should go in alarm within
approximately 3 seconds.
