The LED scanner should have three wires - power, ground, and ground when armed. Hook up the power to 12vdc, hook up the ground to ground, and hook up the ground when armed to the ground when armed output of the alarm. If there is any other device (like a relay) on the ground when armed wire you must diode isolate the current device with the new device.
