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.
Make sure the end of the leader cable with the attached connector is firmly
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 floor 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
This sensor will alarm with a small
quantity of water present.
This sensor requires a larger amount of
water to be present before it alarms.

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

• Make sure the end of the leader cable with the attached connector

• 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 firmly 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 floor, 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.
5. Ram set 6/32 threaded studs in the floor on 2.5” centers or apply mastic.
6. Place the spot detector over the studs or mastic and secure.
