End Line Resistor Wiring Diagram. Using normally closed circuits with properly placed resistors makes it harder to bypass the sensor. Placing resistors anywhere other than the end of the line does nothing to supervise the wiring which is the reason for using resistors.
Normally with end of line you have two resistors one that goes across the contact or pir alarm contacts the second resistor goes from one end of the shunt resistor to one end of the tamper switch as regards the speaker if you put another one of 16ohms on the panel will see 8ohms i would remove the on board one. Single normally closed powered sensor with single. Wires should be soldered onto the resistor and a wire clip can be used on the other end.
Below are diagrams indicating where to place single end of line resistors.
By using this technique you should run a separate circuit for a tamper and a separate. Common elements in the wiring diagram are ground power supply wire and connection output devices switches resistors logic gates lights etc. An eol resistor should always be installed at the last device in the loop and never inside the control panel.
