EOL-P1 概述
What is an End-of-Line resistor? An EOL resistor is the canonical termination element used on conventional fire alarm initiating device circuits, including smoke detector loops, pull-station circuits, and water-flow switch loops. It performs supervisory current metering at the end of a two-wire IDC so the FACP can distinguish between a quiet normal state (resistor seen) and an open or shorted loop (fault state). The EOL resistor sits in the hypernym chain: EOL resistor -> supervisory component -> fire-alarm accessory -> life-safety subsystem -> building life-safety system.
Key features include the inclusion of three specific resistor values (1.1 kOhm, 3.6 kOhm, 4.7 kOhm), ULC listing for Canadian fire alarm installations, compatibility with Edwards FireShield conventional panels, one-piece-per-circuit installation (one resistor plate required per supervised circuit), and through-hole lead-form construction suited to legacy as well as retrofit wiring.
The EOL-P1 uses discrete carbon-film or metal-film through-hole resistors rated for low-voltage DC supervisory current typical of 24 V initiating circuits. Each resistor presents a defined DC impedance to the FACP's sense circuit so the panel can detect current flow changes that correlate to alarm, trouble, or normal states. The plate layout accepts multiple resistor footprints so installers can populate the matching ULC-required value for the specific panel firmware revision.
Typical applications include ULC end-of-line termination for Edwards FireShield 3-zone, 5-zone, and 10-zone conventional fire alarm panels, supervised initiating device circuits for smoke detectors and pull stations, and Canadian-market retrofit installations requiring ULC-listed EOL terminations.
When designing with this kit, remember that only one EOL resistor kit is required per initiating circuit, and choosing the correct resistor value (1.1 kOhm, 3.6 kOhm, or 4.7 kOhm) is dictated by the panel firmware. Verify the required value against the FACP installation manual before populating the plate.

ULC End-of-Line Termination for FireShield FACPs
The Edwards EOL-P1 is the ULC-listed End-of-Line resistor plate specified for the FireShield 3-zone, 5-zone, and 10-zone conventional fire alarm control panels. Why the EOL-P1 fits this use: per the FireAlarm.com and Gordon Electric Supply listings, the kit ships with 1.1 kOhm, 3.6 kOhm, and 4.7 kOhm EOL resistors - the exact values that the FireShield firmware expects to see at the end of each supervised initiating device circuit (IDC). Performance consideration: installed at the far end of the IDC loop (not at intermediate smoke detectors), the EOL-P1's resistor value lets the FACP distinguish a quiet normal state (current through the resistor) from an open-circuit "trouble" state (no return current), without false alarms. One EOL plate is required per circuit, so a fully populated 10-zone panel needs ten EOL-P1 kits for full supervisory coverage.
推荐
Supervised Smoke Detector Loops (Initiating Device Circuits)
The EOL-P1 terminates a conventional two-wire smoke-detector initiating loop at the last detector base, providing the supervisory return path the Edwards FireShield panel measures every few seconds. Why this plate fits: the 4.7 kOhm (or 1.1 kOhm, firmware-dependent) EOL resistor value biases the loop at the DC current level the FACP supervisory circuit expects, ensuring both alarm-current pulses from detectors and the quiet idle state register correctly. Performance consideration: placing the EOL-P1 inside the last detector's junction box (rather than at the FACP) is essential to detect a wire break anywhere along the IDC - a key ULC requirement. Use 18 AWN FPLR or FPLP cable and verify polarity per the FACP terminal label before energizing the loop.
推荐
Conventional Pull Station Notification Loops
The EOL-P1 supervises single-action and double-action pull-station initiating circuits on Edwards FireShield conventional panels. Why the plate fits: per the manufacturer's installation manual reference, pull-station circuits must be terminated with the same ULC-listed EOL resistor value (1.1 k, 3.6 k, or 4.7 kOhm depending on firmware) so the FACP can differentiate an active alarm (short, low impedance) from a quiescent loop (resistor-terminated high impedance). Performance consideration: do not place the EOL-P1 inside the pull station; ULC practice places it at the end-of-line termination box so a break anywhere in the loop drops the supervisory current and triggers a trouble condition.
推荐
Water-Flow Switch Supervisory Circuits
The EOL-P1 supervises sprinkler water-flow switch initiating circuits that feed the Edwards FireShield conventional panel. Why this application fits: the ULC EOL resistor value (1.1 k, 3.6 k, or 4.7 kOhm per firmware) terminates the IDC running out to the flow-switch contacts, allowing the FACP to distinguish a normal (valve-closed, EOL-only) state from an alarm (flow-switch closed) state. Performance consideration: water-flow circuits must use the EOL-P1 termination configuration specified by ULC and the local authority having jurisdiction (AHJ). The resistor values in the kit cover both Sprinkler supervisory and water-flow type IDC configurations across FireShield firmware revisions.
推荐
Canadian-Market ULC Retrofit Installations
For retrofit projects in Canadian commercial, institutional, and high-rise residential buildings where the existing Edwards FireShield panel must be brought up to current ULC listing, the EOL-P1 is the specified EOL termination kit. Why this kit fits: per FireAlarm.com and Gescan, the EOL-P1 explicitly carries ULC listing and ships with the 1.1 k, 3.6 k, and 4.7 kOhm resistor set that matches modern FireShield firmware configurations. Performance consideration: verify the resistor value against the FACP firmware revision (e.g. 3.6 kOhm for some legacy FireShield versions, 4.7 kOhm for newer firmware). Using a non-ULC-listed EOL plate in a Canadian retrofit can void the panel's ULC certification and trigger AHJ rejection of the installation.
推荐
Tamper Switch Supervisory Loops for Sprinkler Valves
The EOL-P1 supervises supervisory IDC loops driven by OS&Y or PIV tamper switches on sprinkler control valves, terminating each loop back to the Edwards FireShield 5-zone or 10-zone panel. Why the kit fits: per the Edwards FireShield family installation documentation mirrored on distributor listings like FireAlarm Max, tamper-switch loops use the same EOL resistor value as alarm circuits but interpret fault states as "supervisory trouble" rather than alarm. Performance consideration: install the EOL-P1 plate at the most-distant tamper switch on the loop, never at the FACP, so that a broken wire anywhere in the supervised circuit reports a trouble condition rather than masking a real tamper event.

设计说明
Always match the EOL-P1 resistor value (1.1 kOhm, 3.6 kOhm, or 4.7 kOhm) to the Edwards FireShield firmware revision configured in the panel. Installing the wrong value almost always generates a persistent 'trouble' condition because the supervisory current falls outside the firmware's expected window. If the FireShield FACP indicates an IDC trouble immediately after power-up, the first item to verify is the EOL resistor value, before re-checking wire continuity.
Per ULC practice, install the EOL-P1 termination plate at the most distant end of the supervised initiating device circuit - never at the FACP terminals and never inside an intermediate detector base. Placing the EOL at the end-of-line allows detection of a wire break anywhere along the IDC; placing the EOL at the FACP masks failures between the panel and the first device. Recommended practice is a listed junction box at the last device location with the EOL-P1 plate screwed in and the resistor leads trimmed and sleeved.
Do not substitute generic carbon or metal-film resistors for the EOL-P1 kit in Canadian fire-alarm installations. The ULC listing is on the entire plate assembly shipped from Edwards, including the validated resistor voltage/temperature ratings and the plate mechanical footprint approved by ULC. An assembled-from-stock alternative may measure the same ohms on a meter but can fail ULC inspection and void the panel's ULC certification.
The EOL-P1 resistors see only the supervisory DC current of the FireShield IDC (typically a few milliamps at 24 VDC), not the alarm-current pulses. No thermal management is required, but verify each resistor's voltage and power rating exceeds the worst-case loop voltage. A typical 1/4 W through-hole resistor is more than sufficient for the supervisory current, but should not be substituted with a 1/8 W part without confirming the worst-case IDC voltage.
Per the Gordon Electric Supply listing, one EOL-P1 is required per supervised circuit. A common installer mistake is to install a single EOL plate at the FACP for all zones, which defeats per-circuit supervision and produces a persistent 'trouble' condition as soon as the second zone is wired in. Always allocate one EOL plate per initiating circuit on the FireShield 3-zone, 5-zone, or 10-zone FACP.
合规信息
ULC-listed (Underwriters Laboratories of Canada) per FireAlarm.com and Gescan SKU descriptions. RoHS/REACH/lead-free status was not present in the retrieved distributor data. The EOL-P1 is a passive fire-alarm accessory, not an automotive-grade IC, so AEC-Q100 does not apply.
