wLSN Water Sensor/
Low‑temperature Sensor
Features
▶
Detects a water puddle with a minimum 77 mm (3 in.)
diameter and 2.5 mm (0.1 in.) depth
▶
Sends a signal to the wLSN Hub in approximately
5 seconds from when the probe is submerged in water
▶
If enabled, sends a signal to the wLSN Hub when the
device temperature drops below +7°C (+45°F)
▶
Provides a Detector Status LED (green)
▶
Uses RF Signal Strength (RFSS) mode to determine
suitability of chosen installation location
▶
Provides supervision for low-battery, cover-tamper,
and wall‑tamper conditions
▶
Operates for up to 3.5 years on readily-obtainable AA
batteries
The wLSN Water Sensor/Low-temperature Sensor detects
water spilled or leaking onto a solid surface. Use it in
security systems for monitoring hot water heaters, clothes
washers, basement water (sump pump failures) and
refrigerator water leaks. It can also be used to monitor
temperature to warn of potential water pipe freezing.
Note The water sensor is not intended to monitor
water levels in storage tanks or liquids other
than water, nor is it intended to be
permanently submerged in water and detect
the absence of water.
Functions
RF Signal Strength (RFSS) Mode
The RFSS mode provides the ability to evaluate RF signal
strength between the wLSN Hub and devices before,
during, and after installation. Device LEDs flash to indicate
the level of signal quality and, if used, the wLSN Installation
Tool indicates signal strength.
Water Probe
As provided, the water probe has 2 m (6 ft) long leads which
connect to the transceiver module through a two position,
plug‑in style terminal block within the transceiver module
enclosure. Lead length can be shortened to meet the needs
of a particular installation.
Low‑temperature Sensor
Monitors the air temperature at the transceiver module
housing (not at the water probe) and sends a signal to the
wLSN Hub when the temperature falls below +7°C (+45°F)
for more than 30 seconds.

Installation/Configuration Notes
Compatibility Information
The wLSN Water Sensor is compatible with the Easy Series
Control Panel, release 3.1 or later, and the wLSN Hub,
release 3.0 or later.
Note Compatibility with Easy Series Control Panel
version 2.5 requires the installer to change the
point type to "24‑Hour" (from "Perimeter").
Mounting Considerations
Mount the water sensors on interior walls or other hard
surfaces where they are protected from weather elements
such as rain or snow. Mount the water probe where a risk
of puddling is anticipated.
Note Installation on metal surfaces or installation
where large metallic objects are between the
transceiver and the wLSN Hub can affect the
RF propagation pattern of the radio
transceiver.
The RF transceiver has an RF range of approximately 1000 m
(3000 ft) in open air. In normal operation, the actual RF
range depends on building construction and other factors.
