1. Optional RF Wet Sensor (Radio Controlled)
The battery powered Optional Wet Sensor is a point
of use water leak early warning accessory which
can be used in conjunction with the Leak Tracker
LD20D system. As soon as the Wet Sensor detects
moisture, a signal is sent directly to the LD20D Leak
Tracker detector valve. Prior to the detector valve
isolating the water supply it first determines if water
is flowing through the system. If no water is flowing
the valve will ignore the Wet Sensor and assume
that the water sensed is a spillage. If water is
flowing the detector valve immediately isolates the
water supply. Both an audio and visual alarm is
activated at the wet-sensor; this allows the wet-
sensor activated to be identified in multi wet-
sensors insulations.
The remote controller also gives an audio warning
to indicate that a wet-sensor has been activated
plus the wet sensor LED on the remote controller
(12) is lit to show that the water has been isolated
by a wet-sensor. (see Leak Tracker LD20D User
Guide
Up to 10 Wet Sensors can be used with a single
LD20D system.
Typical Wet Sensor Locations are: Utility and
laundry rooms, Bathrooms, Kitchens, Loft spaces,
Basements, Pump rooms, beneath hot water tank &
in boiler areas.
2. Installation
Once the most desirable position has been determined
for the wet-pad (this is the damp sensing pad) – under
a washing machine, under a bath, under a shower or
as required, a location for the main body of the wet-
sensor should be identified that can be easily reached
and does not place any strain on the wet-pad cable
when the wet – pad is in the desired position.
The unit will operated with the main body in any
orientation however the back plate supplied is designed
to hold the main body in a vertically plane with the
ariel upper most– ensure that there is sufficient space
above the ariel to allow the main body to be removed
from the back plate without deforming the ariel before
fixing the back plate..
Once the back plate has been fixed remove the battery
cover from the main body and insert a pp3 battery (not
supplied) replace the battery cover and place the main
body on the back plate.
Place the wet pad in the desired position ensuring that
the contacts on the base of the pad are in contact with
the floor or surface to be checked – ensure that the
cable cannot be accidentally moved the unit is now
ready for operation and testing.
3. Testing
To test the unit the test button on the main body of the
Wet Sensor should be pressed and released –
remember unless water is flowing the Leak Tracker
Detector Valve will not operate.
The Wet Sensor should sound a warning and the LED
(warning light) on the main body should illuminate.
Additionally the Remote Controller should sound a
warning and the Wet Sensor warning light illuminate.
Following testing reset the Remote Controller by
pressing and release the reset button (see Leak
Tracker LD20D user instructions)
