END LINE RESISTOR WIRING DIAGRAM
How to Wire an End-of-Line Resistor | eHow
End of line resistors (EOLs) are very important for circuit and loop supervision. When you wire an alarm system, whether it is addressable or conventional, all wired devices -- as well as the loop or the conductors used in wiring -- must be supervised for operation and connectivity by the main panel through the EOLe are two ways to wire EOLs: series and parallel.
End of Line Resistors: Resistor Usage in Alarm Systems
The resistors need to go at the end of the line because they will only supervise the wiring from the resistor to the panel. So if you put the resistor at the panel, it's, again, So just like with the single end of line resistor, you'll have a resistor in series with the sensor, but then you'll also have a resistor in parallel at the sensor.
Why we use Resistors at the end of line on alarm security

Where Should An End-Of-Line Resistor go In A Security System?
Well, for starters, the EOL Resistor (End of Line Resistor) is supposed to go at the end of the loop, as the last device for both security alarm systems and fire alarm systems. However, even though the manufacturer's installation instructions show the EOL Resistor at the end of the circuit, away from the panel, installers of security systems don't always follow this practice.
