3. While the WD861 is in Test mode, set the receiver to Registration mode and
make sure that the transmitter's LED indicator lights up at least twice. After
registration, momentarily close the Tamper switch to terminate Test mode.
Write the number of the zone and the transmitter number (where applicable) on
the sticker provided. Affix the sticker inside the front cover for future reference.
Note: Alternatively, the WD861 can be registered to the receiver by manually
entering the transmitter's serial number.
4. Choose a mounting location. The transmitter should be positioned in a vertical
position high on the wall in order to optimize reception. The sensor should be
placed in a position where water will accumulate rapidly in the event of a flood.
5. Test the transmitter to determine the suitability of your chosen mounting location. To
do so, place the transmitter in the exact mounting position and press the Tamper
switch making certain that the transmissions are successfully received. If
necessary, relocate the transmitter to a better position and repeat the test.
6. To remove the printed circuit board (PCB), press the PCB release tab, carefully
lift the board and slide it away from the back cover. Note: When handling the
PCB, do not apply pressure on the antenna.
7. Knockout the wiring hole in the back cover – see Figure 2.
8. Mount the back cover of the transmitter to the wall using two
screws. Use ISO 7050 (ST3.5 x 22) or similar countersunk
screws so that the screw head will not touch the PCB – see
Figure 1.
9. Thread the sensor's cable through the wiring hole.
10. Connect the sensor's cable to the terminal block as shown
in Figure 2
11. Replace the PCB inside the back cover making sure that it
clicks into place.
12. Before permanently mounting the sensor, place a wet rag over the terminals
(located on the bottom of the sensor).
The WD861 transmits an alarm 30 seconds after detecting the presence of water.
This 30-second delay verifies that the alarm is caused by a significant amount of
water and is designed to prevent false alarms caused by humidity or condensation.
Similarly, the WD861 sends a restore signal 30 seconds after the sensor's terminals
are dry.
When the Tamper switch is open, the 30-second delay is canceled in order to
speed up the test procedure. Make certain that the LED is lit during transmissions.
Note: The LED indicator does not function when the Tamper switch is
closed.
13. Fix the sensor to the floor using the two screws and plugs provided.
Alternatively, you can fix the sensor to the floor using the double-sided
adhesive tape provided – see the following section.
14. Close the front cover of the sensor.
