Supplies for Installation

Included with the LD1000

15 foot (4.57m) leader cable

End-of-line terminator (EOL)

Wall mounting hardware

Available from RLE, sold separately

SeaHawk sensing cable, up to 1000 feet (305m)

Power supply: 24VDC (PSWA-DC-24) or 24VAC (WA-AC-24)

Mount the Device

The LD1000 is a wall mounted device, and mounting hardware is supplied with

every unit.

1. Select a location for the LD1000 and place the two screw anchors in the wall

4.25 inches (107.9mm) apart.

2. Screw both screws into the wall anchors so that approximately 1/8 inch

(3.18mm) of each screw is showing. It may be necessary to adjust the

screws—in or out—so that the unit fits snugly to the wall.

3. Remove the front cover from the LD1000 and hang the rear of the unit on

the screws.

4. Pull the unit toward the ground, so the screws nestle in the top of each

keyhole, and securely fasten the unit to the wall.

** As you wire and configure the LD1000, Refer to Figure A on the back of this page for a

detailed diagram of the device’s internal circuit board and wiring connections. **

Connect the Sensing Cable

Leader cable is used to connect sensing cable to the LD1000, since sensing cable

cannot connect directly to the device.

1. Remove the appropriate circular knockout from the enclosure and thread the

end of the leader cable through the knockout.

2. Insert the four stripped wires of the leader cable into the appropriate slots in

the Cable Input terminal block at the bottom right corner of the LD1000:

White wire: insert into pinout labeled W

Black wire: insert into pinout labeled B

Green wire: insert into pinout labeled G

Red wire: insert into pinout labeled R

3. Unscrew the 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.

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

Connect the Relay Outputs

The LD1000 can be used as a stand-alone device, but it does have two Form

C relay outputs that communicate leak and fault status to another device or

system. If you wish to use the relay outputs, wire them at this time.

Connect the Power

The LD1000 requires an isolated 24VDC or 24VAC power supply. There

are separate terminal blocks for DC and AC power. To avoid product

damage and personal injury, wire power to the corresponding DC or AC terminal

blocks. Establish all wiring connections, including sensing cable, relay outputs,

and power before you activate the board’s power supply.

DIP Switch Settings

The LD1000 has four DIP switches. Adjust the switches to suit your application.

SW1-1
Configure the Relay Outputs as Supervised or Non-supervised

Off (default)

Relays are non-supervised - the relays remains OFF until an alarm is detected

- at which time the relays turns ON.

Relays are supervised - the relays remains ON until either power is disabled or

an alarm is detected - at which time the relays turn OFF.

SW1-2
Configure the Relay Outputs as Latching or Non-latching

Off (default)

Relays are non-latching - when an alarm is detected, the relays will remain in

alarm state until the Quiet/Test/Reset button is pushed, or until the condition

that caused the alarm returns to a normal state.

Relays are latching - when an alarm is detected, the relays will remain in

alarm state until the Quiet/Test/Reset button is pressed.

SW 1-3
Configure Relay Outputs as Two Summary Alarms or as Separate Leak and Fault Alarms

Off (default)

Relay one is a leak alarm; relay two is a fault alarm.

Both relay one and relay two are summary alarms.
