The Kidde EOL-47 is a 47K ohm, 1/2-watt end-of-line supervision resistor for fire alarm and security system circuits. Drop it at the last device on any initiating device circuit (IDC) to maintain line supervision - the panel sees a break instantly if the wire is cut or a device is removed.
Simple install, critical function
Red insulated spade fork terminals connect quickly to screw terminals on the last device in the loop. UL Listed for fire alarm and burglar alarm applications. Rated for indoor dry locations.
Key features
- 47K ohm, 1/2W rating - matches supervision requirements for Edwards/EST and Kidde fire alarm panels
- Spade fork terminals for fast, secure connections at the last device
- UL Listed for fire alarm and burglar alarm circuits
- Indoor dry rated for standard commercial and residential installations
Compatibility
Verify the required EOL resistance value for your specific panel before ordering. 47K ohm is the standard supervision value for Edwards/EST and Kidde Commercial fire alarm control panels.

What resistance value do I need for my fire alarm panel?
The EOL-47 provides 47K ohm supervision resistance - the standard value for Edwards/EST and Kidde Commercial panels. Always verify your panel's required EOL value in the installation manual. Wrong resistance causes trouble conditions.
Where does the EOL resistor install?
At the last device on the initiating device circuit (IDC). Connect across the terminals of the last detector, pull station, or initiating device in the loop. This completes the supervision circuit so the panel detects opens and shorts.
Can I use this for burglar alarm circuits?
Yes. The EOL-47 is UL Listed for both fire alarm and burglar alarm circuits, provided the panel specifies a 47K ohm EOL value. Check your intrusion panel's programming for the correct EOL resistance setting.
Is this rated for outdoor use?
No. The EOL-47 is rated for indoor dry locations only. For outdoor or wet environments, the resistor needs to be housed inside a weatherproof enclosure or junction box.
