NOTE:
End of Line (EOL) Sensing enables the Controller to raise an alarm when
somebody tampers with the circuit (that is, cutting or shorting the wires)
between either Reader 1 Inputs DOS [1] or Reader 2 Inputs DOS [1] and
GROUND (GND). In other words the Controller distinguishes between
tampering on the circuit, and the door being in an actual 'Normally Open'
state.
By placing Resistors into the circuit between either Reader 1 Inputs DOS [1]
or Reader 2 Inputs DOS [1] and GROUND (GND), the Controller's Digital
Input monitors a constant resistance through the circuit. When the circuit is
tampered with, the Resistors are bypassed; the Controller detects the
resistance change raising an alarm.
