Figure 1: End of Line (EOL) Sensing Circuit
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 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
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.
