The Kidde EOL47PK2 is a 2-pack of 4.7K ohm end-of-line supervision resistors built for fire alarm and burglar alarm initiating device circuits. Drop one at the last device on each supervised loop and the panel monitors the circuit for opens, shorts, and grounds - the backbone of NFPA 72 Class B wiring supervision.
Built for the commercial installer
UL Listed for fire alarm and burglar alarm applications, rated for indoor dry locations. The 4.7K ohm value matches Edwards, EST, and Kidde Commercial fire alarm panels and a wide range of burglar alarm panels that specify this resistance for circuit supervision. Spade (fork) terminals connect directly to screw terminals on detectors, modules, and pull stations without crimping or soldering.
Why it matters
- Correct resistance value: 4.7K ohm, the standard supervision value for Edwards/EST/Kidde Commercial panels
- UL Listed for fire alarm and burglar alarm circuit supervision
- Spade terminals for fast, clean connection to screw terminals - no crimping required
- 2-pack keeps a spare on the truck for the next job
- Indoor dry rated (Indoor Dry II environment classification)

What panels use a 4.7K ohm EOL resistor?
Edwards, EST, and Kidde Commercial panels specify 4.7K ohm for IDC supervision. Many burglar alarm panels also use this value. Check the panel install manual to confirm the required EOL resistance.
Where does the EOL resistor get installed?
At the last device on each supervised initiating device circuit (IDC), wired across the circuit terminals. The resistor completes the supervision loop so the panel can detect opens, shorts, and ground faults on the wire run.
Can this resistor be used outdoors?
Rated for indoor dry locations (Indoor Dry II). For outdoor or wet-location circuits, house the resistor inside a weatherproof junction box or use a weather-rated EOL device rated for the environment.
What type of terminals does this resistor have?
Spade (fork) terminals that slide under screw terminals on detectors, modules, pull stations, and junction blocks. No crimping or soldering required.
