Fire Rated Communications Cable RFQ Checklist: 12 Things to Confirm Before Ordering

■ What this checklist is for

This article is designed as an engineering decision reference page rather than a generic product promotion page. Its purpose is to help buyers confirm the real quotation variables behind “fire rated communications cable” before requesting price or approving samples. In practice, the highest RFQ risks usually come from vague wording, such as asking only for “UL fire rated cable” without confirming the installation route, visible marking, conductor type, shielding, or packaging. That is how projects end up with the wrong cable type, wrong compliance evidence, or expensive field rework.

A good RFQ should support five practical goals: first, directly answer what must be confirmed before ordering; second, help engineers and procurement teams compare cable types by route and application; third, reduce compatibility and inspection errors; fourth, control hidden cost from substitution or rework; and fifth, make the page easier for technical buyers and search engines to understand.

■ Why “fire rated communications cable” is not enough

“Fire rated communications cable” is only a buying shortcut. It does not tell the supplier whether the project needs a plenum cable, a riser cable, a general-purpose communications cable, a fire alarm cable, a Class 2 / Class 3 cable, an optical fiber cable, or a hybrid construction. It also does not define whether the project is governed by NEC-style installation logic, a fire alarm specification, or a cross-border material and documentation requirement.

In other words, a cable can be “fire rated” in a broad commercial sense and still be wrong for the actual route. A quotation should therefore follow a simple hierarchy: application first, cable marking second, construction third, evidence fourth.

■ The 12 things to confirm before ordering

1) Application

Begin the RFQ with the actual use case: commercial LAN, BMS, access control, voice/data, fire alarm, backbone, industrial communication, or mixed-signal control. Then define the physical route: plenum space, riser shaft, general indoor horizontal run, indoor/outdoor transition, or outdoor exposure. Without that context, the supplier may quote the wrong cable family.

2) UL type

The type marking is the fastest way to turn a vague request into a quoteable product definition. In many communications projects, the most common visible type codes are CMP, CMR and CM, but some projects may instead require CL2P, CL2R, FPLP, FPLR, OFNP or OFNR. Put the required type in the RFQ instead of asking only for “UL fire rated cable.”

3) Jacket rating

Confirm the installation-related rating separately from the jacket material. A cable may be plenum-rated, riser-rated or general-purpose, but the jacket material may still be PVC, PE, LSZH or another compound. In addition, indoor/outdoor, sunlight resistance, temperature range and color may also matter to the project.

4) AWG

AWG influences resistance, conductor diameter, bending behavior, PoE heat rise and connector compatibility. In Ethernet projects, 23AWG and 24AWG are common. In alarm, control and BMS wiring, 18AWG to 22AWG may also appear depending on the design. For longer links, larger current load or PoE++, the conductor size becomes more important.

5) Conductor

Do not leave conductor material open to assumption. A quotation may look attractive until the actual conductor is revealed to be different from the project expectation. Confirm whether the conductor is solid or stranded, and whether the material is bare copper, tinned copper or another construction. For structured cabling, especially PoE and permanent links, solid bare copper is often the safest requirement to state clearly.

6) Shielding

If the route passes near motors, drives, transformers, access control hardware or other EMI-heavy environments, shielding should be confirmed in the RFQ. State whether the cable is U/UTP, F/UTP, U/FTP, S/FTP or another shield structure, and whether a drain wire is required. Shielding decisions should also be consistent with the grounding plan and connector selection.

7) Cable structure

Confirm the actual construction, not just the category or application name. For example, a LAN cable may need 4 pairs, a separator, a specific outer diameter and a defined twist structure. A control cable may need 1 pair, 2 pairs or multiple cores with foil shield and drain wire. A fiber cable may need a different strength member, fiber count and jacket logic. The RFQ should prevent unapproved substitutions.

8) Performance

Fire rating is not the same as transmission performance. If the project is for structured cabling, state the performance target: Category 5e, Category 6, Category 6A, impedance, bandwidth, channel or permanent link expectation, and whether PoE suitability must be considered. If the cable is for a special protocol, such as a control bus, include the impedance or signal requirements.

9) Printing

The jacket marking helps field verification, warehouse control and project inspection. A good RFQ should specify the expected printing content, such as brand, cable type, AWG, category, conductor note, length mark, lot traceability and customer code. If the project has a private label or OEM requirement, that should be confirmed before sampling.

10) UL file

Ask for certification evidence, not just a product image. The supplier should be able to provide a UL file reference or equivalent listing evidence, along with a matching marking sample and product data sheet. This is especially important for submittal approval, pre-shipment document review and project compliance checks.

11) Box / reel

Packaging affects installation speed and logistics cost. Pull box, plastic reel, wooden reel or drum should be confirmed together with length per package, labeling, palletization and shipment method. A correct cable packed the wrong way can still create project delays or field handling problems.

12) Delivery documents

A complete RFQ package should request the data sheet, marking sample, packaging label sample, compliance declaration and any project-specific approval document. This reduces the chance that the technical agreement and the shipped goods diverge later.

■ LSZH vs CMP for cross-border projects

LSZH and CMP are often mixed together in international purchasing, but they are not interchangeable concepts. LSZH mainly refers to low-smoke, zero-halogen material behavior. It is widely used in European and many international projects, especially where CPR-style language and material response are part of the compliance discussion. CMP, by contrast, is a North American plenum-oriented installation rating used in NEC-based projects and tied to stricter fire and smoke expectations for air-handling spaces.

The practical rule is simple: LSZH describes material behavior; CMP describes a specific installation acceptance route. For cross-border RFQs, confirm both the regional compliance route and the exact visible cable marking the project expects. A buyer should not assume that “LSZH” automatically satisfies a plenum requirement, and should not assume that “PVC” automatically means the cable is unsuitable in all cases either. The project specification and installation code still control the decision.

■ PoE / PoE++ risk control: why AWG and conductor quality matter

For PoE and especially PoE++ projects, fire rating alone is not enough. Remote power delivery increases the importance of conductor size, conductor consistency and heat management. A cable that is acceptable by installation route can still underperform or create risk if the conductor quality is poor or the electrical resistance is unstable. That is why the RFQ should clearly state conductor material, AWG and whether the project requires data on DC resistance or DC resistance unbalance.

DC resistance unbalance becomes more important as power moves across all four pairs in higher-power Ethernet systems. If conductor resistance is uneven, current distribution may become uneven too, which can increase heat concentration, power loss and long-term reliability problems. This is one reason low-grade conductor constructions, especially unspecified or cost-driven alternatives, should not be used casually in PoE-heavy projects.

■ Cost and risk structure

The lowest cable price is not the lowest project cost. In most real-world jobs, the biggest losses come from rework, approval delay, field replacement and integration failure, not from the cable unit price itself. This is why a complete RFQ creates cost control, not just technical control.

■ Conclusion

The safest way to buy fire rated communications cable is to treat the RFQ as a technical control document, not just a pricing request. Application route determines the basic compliance path. Visible cable marking confirms the intended use. AWG, conductor, shielding and structure control real-world performance. Printing, packaging and certification evidence complete the purchasing logic.

In short, a better RFQ follows this order: application first → marking second → construction third → evidence before order. That approach reduces specification mismatch, approval delay and rework cost while improving purchasing speed and project confidence.
