Overview & Identication
The Water Leak Detector is designed to sense the presence of water and alert a central monitoring system of the
potentially destructive situation. Upon water detection, an alarm relay changes state, and a local red LED illuminates.
The transmitter can be set for latching alarm or non-latching alarm with normally energized or de-energized operation.
An optional remote water sensor is available for small inaccessible locations such as AHU pans or under oor water
detection.

Mounting
Place the transmitter in a location where a water leak is
likely to cause damage such as a cooling coil pan, a hot
water tank pan, under a sink, under an elevated oor,
or in a drop ceiling under pipes. The transmitter can be
independently mounted in a visible location by using a
remote water sensor and waterproof cable as shown
in Fig. 4. Terminate the transmitter as shown in the
termination section.
1. Set the transmitter where water is most likely to be a
problem or in the collection pan under the water coil or
heater (Fig. 5).
• Alternatively a water sensor or remote water sensor
can be attached to the pan edge with two set screws
(Fig. 6). Do not over tighten or puncture the pan.
• Alternatively a remote water sensor can be attached
to the pan or oor with mounting tape (Fig. 7). Clean
surface thoroughly before setting the sensor in place
and push sensor down rmly. Mount the detector
enclosure in a visible location within cable length of the
remote water sensor.
• Alternatively a remote water sensor can be attached
to the oor with screws (Fig. 8). Mount the detector
enclosure in a more visible location within cable length
of the remote water sensor.
• Alternatively the rope water sensor can be laid on the
oor or under pipes as shown in Figs. 10, 11, 12 & 13.
Cable clamps can be used to secure the sensor to the
oor.
2. Adjust the depth screw on the sensor probe in the middle
of the open enclosure to the alarm depth (Fig. 5). If using
a remote water sensor, adjust the depth screw as shown
in Fig. 9. The rope sensor detects water 1/8” off the oor
and has no adjustment.
3. Run the cable to the transmitter location leaving enough
slack to terminate and allow for some repositioning as
needed. Use a strain relief on the entering cable so the
wires do not tug on the terminals directly.
4. Terminate and congure in accordance with the
termination section.

Down
1. Loosen wing nut.
2. Set the required depth of the
sensor probe screw using a #2
Phillips screwdriver.
3. Hold the sensor probe screw
stationary with the screwdriver.
4. Turn the wing nut down the probe
screw until it engages the plastic.
5. Tighten the wing nut 1/4 turn into
the plastic.
