OPERATION
The WST-621 sensor isdesigned todetect water across the gold
probes and will alert immediately when present. The Freeze sensor will
trigger when the temperature isbelow 41°F (5°C) and will send a
restoral at 45°F (7°C).
ENROLLING
To enroll the sensor, set your panel into sensor learn mode. Refer to
your specific alarm panel instruction manual for details on these
menus.
1. On the WST-621 locate the pry points on opposite edges ofthe
sensor. Carefully use a plastic pry tool or standard slot head
screwdriver to remove the top cover. (Tools not included)
2. Insert the CR2450 battery with the (+) symbol facing up, if not
already installed.
3. To learn in as a flood sensor, press and hold the Learn Button
(SW1) for 1 - 2 seconds, then release. A single short on/off blink
at 1 second confirms flood learn is initiated. The LED will remain
solid ON during the learn transmission. The Flood sensor enrolls
as Loop 1. Repeat as required.
4. To learn the freeze sensor, press and hold the Learn Button
(SW1) for 2 - 3 seconds, then release. A single short on/off blink
at 1 second plus a double on/off blink at 2 seconds confirms
freeze learn is initiated. The LED will remain solid ON during the
learn transmission. The Freeze sensor enrolls as Loop 2. Repeat
as required.
5. After successful enrollment, verify the gasket in the top cover is
properly seated, then snap the top cover onto the bottom
cover aligning the flat sides. Inspect the seam all the way
around the edge of the device to ensure it is completely
sealed.
Note: Alternately, the 7 digit serial number printed on the back of each unit can be manually entered into the
panel. For 2GIG systems the equipment code is “0637”
Testing the Unit
After successful enrollment, a test transmission sending current states
can be initiated by pressing and immediately releasing the Learn
Button (SW1), with the top cover open. The LED will remain solid ON
during the button-initiated test transmission. With the unit fully
assembled and sealed, placing wet fingers on any two probes will
trigger a flood transmission. Note the LED will not illuminate for a wet
flood test and remains OFF during all normal operation.
PLACEMENT
Place the flood detector anywhere that you wish to detect a flood or
freezing temperature, such as under a sink, in or near a hot water
heater, a basement or behind a washing machine. As a best practice
send a test transmission from the desired placement location to ensure
the panel can receive it.

USING OPTIONAL ACCESSORIES
The optional accessories enhance the Flood and Freeze Sensor
installation by allowing additional installation locations, mounting on
vertical surfaces such as walls or cabinet interiors with the External
Sensor Adapter / Mounting Bracket and included screws. The Water
Detection Rope can be routed down and across the floor covering a
larger detection area. The length of the Water Detection Rope jacket
is the detection area.
Setup
1. Be sure to complete all enrollment steps before installing optional
accessories.
2. Plug the Water Detection Rope into the socket located on the
end of the External Sensor Adapter / Mounting Bracket.
3. Wrap the Water Detection Rope around the strain relief / retension
posts on the back of the External Sensor Adapter / Mounting
Bracket to prevent the rope from being inadvertantly unplugged.
4. Use screws to secure the External Sensor Adapter / Mounting
Bracket, if desired.
5. Align the flat sides of the Flood and Freeze Sensor with the sides of
the External Sensor Adapter / Mounting Bracket. Then snap the
sensor into the bracket esuring the sensor is fully seated and the
three retention tabs are fully engaged.
6. Route the length of the Water Detection Rope across the
horizontal surface(s) to be monitored for water.
Notes:
•Up to ten (10) Water Detection Rope sensors can be chained
together to futher extend the detection area(s).
•Once water detection occurs using the Water Detection Rope, it
may take several hours for the rope to sufficiently dry and a
restore signal to be sent.Adequate ventilation will speed the
drying process.
•Improper connections between the WST-621 Flood and Freeze
Sensor, the External Sensor Adapter / Mounting Bracket,and the
Water Detection Rope can prevent flood detection, or cause
false flood restore. Always verify connections are secure.
REPLACING THE BATTERY
When the battery is low a signal will be sent to the control panel. To
replace the battery:
1. On the WST-621 locate the pry points on opposite edges ofthe
sensor, carefully use a plastic pry tool orstandard slot head
screwdriver to remove the top cover. (Tools not included)
2. Carefully remove the old battery.
3. Insert the new CR2450 battery with the(+) symbol facing up.
4. Verify the gasket inthe top cover isproperly seated, then snap
the topcover onto thebottom cover, aligning theflat sides.
Inspect the seam allthe way around the edge of the device to
ensure itiscompletely sealed.
