so the screws nestle in the top of each keyhole and
securely fasten the unit to the wall. Before reattaching the front of the unit, make all wiring connections and set all
switches to the desired setting (see below for configurations).

2. Power
Connections
The LD1000 requires 24VAC or 24VDC. Make sure to wire the appropriate power to the appropriate terminal blocks
on the LD1000 to avoid damage or injury (ie DC power must only be wired to the terminal blocks labeled DC IN
and AC power must only be wired to the terminal blocks labeled AC IN). If using DC power, the power supply
must be an isolated power supply (part #WA-DC-24-ST).

3. Cable
Installation
The LD1000 requires a separate leader cable (part #LC-KIT) that connects the sense cable to the unit and
terminates the line of sensing cable properly. Connect the stripped end of the 15 foot (4.57m) leader cable to the
terminal block labeled TB1 on the main board of the LD1000. From left to right, with the screws of the terminal
block connector facing up, the leader cable wires should be connected white, black, green, and red. Once the
leader cable is plugged into the terminal blocks, it is ready to be connected to the leak detection cable. To do this,
unscrew the end terminator from the end of the leader cable. Attach the first length of water leak detection cable to
the leader cable. Route the water leak detection cable according to a cable layout diagram, if provided. Secure the
end terminator on the unoccupied end of the leak detection cable.












4. Leak
Sensitivity
Adjust R25 (see diagram below) to set the desired leak sensitivity. By default, it is set to the mid-sensitivity setting
(150uA) and may be adjusted to the low (300uA) or high (25uA) sensitivity setting by turning the dial.

Dipswitch Settings
SW1-1: Configures the output relays as supervised or non-supervised. If the relays are supervised, the relays will
remain on until either power is disabled or an alarm is detected (relay will turn off). If the relays are non-supervised,
the relays will turn on upon an alarm being detected.

Off Non-supervised (Factory Default)
On Supervised

SW1-2: Configures the relays as latching or non-latching. If the relays are latching, then the relay will remain in
alarm state (depending on SW1-1, supervisory setting) upon alarm until the Quiet/Reset/Test switch is pressed. If
the relays are non-latching, then the relay will remain in an alarm state upon alarm until the Quiet/Reset/Test switch
is pressed or the condition that caused the alarm returns to normal.

Off Non-latching (Factory Default)
On Latching


SW1-3: Configures the two output relays as a summary alarm or as two separate leak and fault alarms.

Off Relay One is a Leak Alarm and Relay Two is a Fault Alarm (Factory Default)

On Relay One is a Summary Alarm and Relay Two is unused

SW1-4: Configures the Alarm Delay setting. This is the response time it takes for the unit to report an alarm
condition (Leak or Fault) once detected. The alarm must be present during this entire period.

Off 10 Seconds (Factory Default)
On 2 Minutes

5. Audible
Alarm
Setting
The audible alarm may be disabled for the LD1000. Remove the jumper cap from JMP2 to disable. This jumper
cap is required if audible alarms are desired.
