			Note: The LED will not stop flashing if there is
				another system fault present.
			If there is no keypad nearby, or another control
			problem exists, you can use a volt-meter to find the
			ground fault:
			1)	Connect the negative lead of a volt-meter to the
				panel ground terminal.
			2)	Connect the positive terminal to the Aux Power –
				terminal.
			You should read -4.5 to -7.5 Volts DC. A reading
			considerably higher or lower indicates a ground
			fault.
			Disconnect field wiring from each terminal while
			watching the meter. When the voltage reading
			returns to between -4.5 and -7.5 VDC, you have
			found the wire that is causing the ground fault.
