The Kidde EOL3.6-1.1 is a matched pair of end-of-line resistors (one 3.6K ohm, one 1.1K ohm) for supervising initiating device circuits and notification appliance circuits on compatible Kidde and EST fire alarm panels. Drop one kit at the last device on each zone - no sourcing loose resistors from the parts bin, no second-guessing values on the job.
Why stock these
Mismatched or wrong-value EOL resistors cause nuisance trouble signals and wasted troubleshooting time. This factory-packaged kit gives you the exact resistance pair the panel expects, in one bag, ready to terminate. Keeps your truck stocked and your punch list short.
Key details

What are these EOL resistors used for?
EOL resistors wire at the last device on a supervised fire alarm circuit (IDC or NAC). They let the panel detect opens, shorts, and ground faults by monitoring loop resistance. Wrong values cause nuisance trouble signals.
Which panels use 3.6K and 1.1K ohm EOL values?
Kidde and EST intelligent and conventional fire alarm panels that use a dual-resistor supervision scheme. Always verify against your panel's installation manual - wrong EOL values cause trouble conditions.
How many resistors come in this kit?
One 3.6K ohm resistor and one 1.1K ohm resistor - enough to terminate one supervised circuit.
Can I use these on non-Kidde panels?
Only if the panel requires exactly 3.6K and 1.1K ohm EOL values. Every manufacturer specifies exact resistance values. Wrong values cause trouble conditions. Verify against the panel's install docs before using.
