The backplane has several control LEDs. The system is OK if all the green LEDs
(detector 1, detector 2, Key units 1 to 3) light up while the gate is not active. If
the gate gets an OPEN command, one of the orange LEDs (for the active input)
will light up. If the gate gets a CLOSE command, one of the red LEDs (for the
active input) will light up.
The "OPEN" and "CLOSE" keys are used to open or close the gate.
