System Sensor ELR-47K

Product Overview

 The ELR-47K is a 47,000-ohm end-of-line resistor assembly used to supervise initiating device circuits in fire alarm systems. Installed at the end of the circuit, it provides the required termination resistance to allow the fire alarm control panel to accurately monitor circuit integrity and identify open or short conditions in compliance with manufacturer specifications and applicable codes. Designed for use with multiple Honeywell fire alarm platforms, this EOL resistor supports consistent and reliable system supervision.
