Kidde - Edwards EOL-15 End-of-line Resistor 15k Ohm

Product Description

The KIDDE - EDWARDS EOL-15 is an end-of-line (EOL) resistor rated at 15,000 ohms (15k ohm), used in fire alarm and life safety systems to supervise initiating device circuits (IDC) and signaling line circuits. EOL resistors are placed at the last device on a supervised circuit loop, allowing the fire alarm control panel to continuously monitor the circuit for open or short conditions. This component is sold as an individual unit and is installed by licensed fire alarm technicians as part of a code-compliant system installation.

The EOL-15 is suited for residential and commercial fire alarm applications where a 15k ohm end-of-line supervision value is specified by the control panel manufacturer or the system design. It is a standard accessory used during new installation, panel replacement, or circuit expansion work on compatible KIDDE - EDWARDS fire alarm systems and control panels that require 15k ohm supervision resistors.

Key Features

• 15,000 ohm (15k ohm) resistance value for circuit supervision
• Designed for end-of-line placement on supervised initiating device circuits
• Enables control panel to detect open and short circuit fault conditions
• Sold individually for flexible installation and replacement use
• Fire power accessory category — compatible with supervised fire alarm circuit designs

Compatibility

Designed as an OEM-style end-of-line resistor accessory for supervised fire alarm initiating device circuits requiring a 15k ohm termination value. Consult the specific control panel installation manual to confirm the required EOL resistance value before installation.

Installation Notes

EOL resistors are installed by qualified fire alarm technicians in accordance with NFPA 72 and the control panel manufacturer instructions. De-energize and disable the affected circuit zone at the fire alarm control panel before making any wiring connections. The resistor is placed at the last device on the supervised circuit, not at the panel. Verify the correct ohm value against the panel documentation before installation, as using an incorrect resistance value will cause a trouble or fault condition.
