The Kidde EOL-15 is a 15K Ohm end-of-line resistor built for supervised fire alarm and burglar alarm signaling circuits. Spade (fork) terminals connect directly to screw terminals on initiating device circuits, notification appliance circuits, and signaling line circuits where 15K Ohm supervision is specified.
Built for clean inspections
UL Listed under the Signaling category (3KMU), rated for indoor dry locations. When the AHJ walks the job, this resistor checks the box without a conversation. Pre-labeled with the Edwards model number, resistance value, and UL mark for fast visual verification during final inspection.

What is an end-of-line resistor used for?
An EOL resistor terminates a supervised circuit on a fire or burglar alarm panel. The panel monitors loop resistance - if the resistor is removed or the wiring shorts, the panel flags a trouble or alarm condition.
Which panels require a 15K Ohm EOL resistor?
The EOL-15 is the standard supervision resistor for Kidde (Edwards) fire alarm panels and select burglar alarm systems specifying 15K Ohm supervision. Check your panel's install manual for the required EOL value.
Can I use this on outdoor circuits?
No. The EOL-15 is UL Listed for indoor dry locations only. For outdoor or wet environments, the resistor must be housed in a weatherproof enclosure rated for the application.
Is this EOL resistor UL Listed?
Yes. UL Listed under the Signaling category (3KMU) for fire alarm subassembly and burglar alarm applications.
