Use tape that is 0.5 inch (1.27cm) wide. When placed correctly, the tape allows
the transmitter’s back label to remain visible. The serial number on this label is
unique to each transmitter, and you will need to refer to this number throughout
the life span of the transmitter. If tape is placed over the label, the paper label
will tear and the serial number will be unreadable.

Battery

Each transmitter comes equipped with a

3.6V lithium battery, which can be replaced
as needed. The transmitter is turned off
when the product is shipped. Any time the
transmitter is shipped, it should either be
returned to this inactive state or placed in
a shielded container to prevent interference
that might cause shipping problems.

To activate the transmitter, remove the pull
tab to engage the battery. Turn off the
transmitter by re-inserting the pull tab or
removing the battery.

The transmitter can be mounted with
adhesive tape, adhesive-backed velcro or
adhesive-backed magnetic tape, which
works well if the transmitter will be mounted
on a metallic surface and will not disturb
the electronics. You’ll need access to the
information on the transmitter’s label - the
white sticker on the back of the unit. When

Installation Mode Switch

The transmitter has an installation mode switch - a
push button located in the center of the enclosure
lid. When pressed, the transmitter immediately
sends a data packet with a special mark introduced
into its ID eld. This indicates which transmitter is
in service or being installed. The data is processed
by the FDS-Wi’s automatic discovery feature. For
more information regarding the FDS-Wi and wireless
sensor integration, refer to the FDS-Wi User Guide.

Wi-LD Congurations

A Wi-LD conguration couples the wireless transmitter with one of the following
three options:

1. up to 50 feet (15.24m) of conductive uid sensing cable

2. up to 35 feet (10.67m) of chemical sensing cable

3. one SD-Z spot detector

4. one SD-Z1 spot detector
If you are using either sensing cable or an SD-Z spot detector, you may use as
much leader cable as you need to reach the area you plan to monitor.

Connect Sensing Cable to the Wi-LD

Connecting up to 50 feet of sensing cable to the Wi-LD creates a single-zone leak
detection solution.

1. Mount and activate the Wi-LD transmitter. Verify the heartbeat LED is
blinking.

2. Leader cable is used to connect sensing cable to the transmitter, since
sensing cable cannot directly connect to the transmitter. Leader cable
comes with four open wires that allow it to be wired directly to the
transmitter’s terminal block. Since the leader cable has four wires and
there are two terminal block pinouts on the Wi-LD, two wires need to be
inserted into each pinout. The white and black wires both go into the left
pinout. The red and green wires both go into the right pinout. Insert the
leader cable wires into the pinouts and tighten the screws.

Wi-LD, two wires need to be inserted into each pinout. The white
and black wires both go into the left pinout. The red and green
wires both go into the right pinout. Insert the leader cable wires
into the pinouts and tighten the screws.

• Make sure the end of the leader cable with the attached connector
is rmly inserted into the terminal block.

• Unscrew the end-of-line terminator (EOL) from the end of the
leader cable.

• Attach the SD-Z to the end of the leader cable.

• Secure the EOL to the cable on the unoccupied end of the SD-Z.

b. The SD-Z1 comes with a four-wire open lead that allows it to be wired

directly to the transmitter’s terminal block.

• Since the lead has four wires and there are two terminal block
pinouts on the Wi-LD, two wires need to be inserted into each
pinout. The white and black wires both go into the left pinout.
The red and green wires both go into the right pinout. Insert the
wires into the pinouts and tighten the screws.

Make sure the end of the leader cable with the attached connector is rmly
inserted into the Wi-LD’s terminal block.

3. Unscrew the end-of-line terminator (EOL) from the end of the leader cable.

4. Attach the length of sensing cable to the leader cable.

5. Route the sensing cable according to your cable layout diagram. Secure
the cable to the oor with J-clips or mastic as needed.

6. Secure the EOL to the unoccupied end of the sensing cable.

Connect a Spot Detector to the Wi-LD

A spot detector is designed to detect and report the presence of liquids in a
single area. Either an SD-Z or an SD-Z1 can be connected to a Wi-LD.

1. Mount and activate the Wi-LD transmitter. Verify the heartbeat LED is
blinking.

2. Verify which type of spot detector you’re using, since they each connect to
the Wi-LD differently.
a. The SD-Z requires leader cable to connect to the Wi-LD transmitter.

• Leader cable comes with four open wires that allow it to be wired
directly to the transmitter’s terminal block. Since the leader cable
has four wires and there are two terminal block pinouts on the

SD-Z1

• Make sure the end of the leader cable with the attached connector
is rmly inserted into the terminal block.

3. Determine the spot detector’s location

4. The angle of the sense probes can be adjusted to change the sensitivity
of the SD. The closer the probes are to the oor, the smaller the quantity
of liquid required to trigger the sensor. Adjust the sense probes to the
desired height. Be sure the probes don’t touch each other.

This sensor will alarm with a small

5. Ram set 6/32 threaded studs in the oor on 2.5” centers or apply mastic.

6. Place the spot detector over the studs or mastic and secure.

This sensor requires a larger amount of

water to be present before it alarms.
