Ecolink WST-621 Flood and Freeze Sensor
Product Information
The WST-621 Flood and Freeze Sensor is a patent-pending device that operates at a frequency of 319.5 MHz and uses a 3Vdc lithium CR2450 (620mAH) battery. It is compatible with Interlogix / GE receivers and has a supervisory signal interval of approximately 64 minutes.
Enrolling the Sensor
To enroll the sensor, set your panel into sensor learn mode. Refer to your
specific alarm panel instruction manual for details on these menus. Flood and
freeze will enroll on separate serial numbers.
- Locate the pry points on opposite edges of the sensor. Carefully use a plastic pry tool or standard slot head screwdriver to remove the top cover. (Tools not included)
- Insert the CR2450 battery with the (+) symbol facing up, if not already installed.
- To learn in as a flood sensor, press and hold the Learn Button (SW1) for 1 – 2 seconds, then release.
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
operations.
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, in
a basement, or behind a washing machine.
FCC Compliance Statement
The WST-621 Flood and Freeze Sensor complies with FCC ID: XQC-WST621 IC:9863B- WST621.

OPERATION
The WST-621 sensor is designed to detect water across the gold probes and will alert immediately when present. The Freeze sensor will trigger when the temperature is below 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. Flood and freeze will enroll on separate serial numbers.
- On the WST-621 locate the pry points on opposite edges of the sensor. Carefully use a plastic pry tool or standard slot-head screwdriver to remove the top cover. (Tools not included)
- Insert the CR2450 battery with the (+) symbol facing up, if not already installed.
- To learn in as a flood sensor, press and hold the Learn Button (SW1) for 1 – 2 seconds, then release. A single shot on/off blink at 1 second confirms flood learn is initiated. The LED will remain solid ON during the learning transmission. Repeat as required.
- To learn the freeze sensor, press and hold the Learn Button (SW1) for 2 – 3 seconds, then release. A single shot 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 learning transmission. Repeat as required.
- 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.

REPLACING THE BATTERY
When the battery is low a signal will be sent to the control panel. To replace the battery:
- On the WST-621 locate the pry points on opposite edges of the sensor, carefully use a plastic pry tool or standard slot head screwdriver to remove the top cover. (Tools not included)
- Carefully remove the old battery.
- Insert the new CR2450 battery with the (+) symbol facing up.
- 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
