Fire-Lite ELR-47K Firelite Assy,Fnl, Resistor 47K Ohms

The Fire-Lite ELR-47K is a factory-assembled end-of-line resistor component designed specifically for use within Fire-Lite fire alarm system circuits. End-of-line resistors serve a critical supervisory function in initiating device circuits and notification appliance circuits, allowing the fire alarm control panel to continuously monitor circuit integrity and detect open or short-circuit fault conditions. By maintaining the correct supervisory current path at the terminal point of a circuit loop, this component enables the panel to distinguish between a normal standby state, an alarm condition, and a wiring fault — a foundational requirement in life-safety system design. The ELR-47K is intended for professional fire alarm installers, system integrators, and service technicians who require a genuine Fire-Lite assembly to maintain circuit compliance and system reliability in commercial, institutional, and industrial installations.
