The Simplex 4081-9008 End-of-Line Wire is a crucial component for monitoring wiring continuity in Class B fire alarm circuits. It's an End-of-Line Resistor (EOLR) designed to be connected at remote locations where EOL resistors are required. This ensures the fire alarm control panel (FACP) can detect three states: normal, short circuit, and open circuit. The resistor value is 10kΩ at 1/2W, with 600V black insulation and 13mm stripped leads. Its primary purpose is to supervise the integrity of alarm circuits, preventing unnoticed faults that could compromise safety. It's a genuine Simplex component, emphasizing reliability and compatibility with Simplex systems.
