Fire-rated cable basics for sellers.
The print on the jacket decides what fire-rated cable is. FPLR, FPLP and CI are three different products, and a two-hour system is a fourth thing again.

01
The three ratings you will actually meet
FPLR is riser-rated fire alarm cable, for vertical runs in a shaft where a fire would otherwise use the cable as a path between floors. FPLP is plenum-rated, for the return-air space above a ceiling, and it carries a heavier test burden. CI is circuit integrity, tested to keep a circuit alive for a stated period, and it is a system claim as much as a cable claim.
- FPLR: riser rated, vertical shafts
- FPLP: plenum rated, return-air spaces
- CI: circuit integrity for a stated period
- Two-hour systems: rated as an assembly, not a cable
- NPLF and other legacy markings still on older stock
02
A two-hour system is an assembly
Two-hour fire-rated systems are tested as a complete assembly: the cable, the raceway, the supports, the boxes and the method of fastening. The cable alone does not carry the rating, which is why a reel of two-hour cable without documentation is bought as high-temperature cable rather than as a rated system. The listing report and the installation instructions are what support the claim. Without them the reel is good cable, just not a system.
03
The print that decides value
Read the legend from the outer jacket, not from a label. It should carry the manufacturer, the product family, the temperature rating, the voltage, the applicable standard and the listing mark. A reel where that legend is legible, unbroken and consistent with its tag is straightforward to buy. One where the legend has been bleached by the sun or covered by overspray is a different conversation.
04
What kills the value
Fire-rated cable is damaged by the same things as any other cable, and the damage costs more because the product is worth more. Sun bleaches the print until the rating is unreadable. Paint and overspray from a refit cover the legend. A reel left on wet ground wicks water into the wraps. Cut lengths lose the print at the ends, and with it the evidence.
- Faded or painted-over jacket legend
- Cut lengths with no readable print
- No listing documentation behind a system claim
- Crushed armour or a flattened cable on the reel
| Family | Where it is used | Print to look for |
|---|---|---|
| FPLR | Riser shafts, fire alarm | FPLR and the listing mark |
| FPLP | Plenum return-air spaces | FPLP with the standard |
| CI cable | Circuits that must survive | CI and the rated period |
| Two-hour system cable | Life-safety feeder circuits | System listing plus report |
| Legacy NPLF | Older fire alarm work | NPLF, often faded |
Questions
Answers before you send anything.
If your question is not here, call the desk. A buyer answers, not a call centre.
How do I tell FPLR from FPLP on a reel?
Read the jacket. The legend is printed at intervals along the cable and states the rating family directly, with the temperature and voltage. On a full reel the outer wrap is enough to read it. On a partial you may need to unwind a turn or two.
Is all red cable fire-rated?
No. Red is a common jacket colour for fire alarm and life-safety circuits, and it is used for other things as well. The colour is a convention, not a rating. Only the print decides what the cable is, and a red jacket with a faded legend has to be read another way.
Can cut lengths be sold as fire-rated?
They can be bought, at a value that reflects the loss of the print and the loss of a tag. A length long enough to read the legend on, with the tag kept alongside it, is a much better proposition than a coil with nothing to identify it.
Does the reel need the original listing paperwork?
For plain FPLR and FPLP, no, because the print carries the rating. For a two-hour system, yes, because the rating belongs to the assembly and the report is what supports it. Those are two different sales and they should not be described the same way.
