Overview
Ensure dependable circuit supervision and simplify maintenance with the Federal Signal EOL/Series Resistor Module. This fire alarm control panel accessory — model K859901989A-33000 — delivers a precise 33K ohm end-of-line termination that stabilizes loop resistance for reliable monitoring and reduces nuisance alarms. Engineered for use with Federal Signal break glass and push-button call points, the compact resistor module installs directly in series circuits to provide clear end-of-line supervision for fire alarm, security and surveillance systems. By standardizing termination resistance, the resistor helps control panel electronics accurately detect open, short or tamper conditions, speeding troubleshooting and reducing system downtime. Its form factor and compatibility with flameproof, GRP-enclosed call points make it a practical choice for hazardous-location deployments where consistent monitoring is essential. Specify the K859901989A-33000 EOL resistor in your next fire alarm or security design to improve loop reliability and simplify field servicing. Contact your supplier or order now to add robust end-of-line protection to your installation.
