■ Introduction: Why Fire Cable Compliance Matters
In the European Union, the integration of fire safety standards related to building materials—cables included—works under the aegis of a single regulatory framework known as the Construction Products Regulation (CPR). For electrical and communication cable installations, this rule ensures that cables used in permanent buildings are made according to strict specifications regarding their fire resistance, smoke emission, and toxicity.
Zion Communication's CPR-compliant branded fire cables are created to satisfy the highest safety standards, and at the same time, they guarantee uninterrupted power and data transit during emergencies.
The CPR (Construction Products Regulation), also known as EN 50575:2014+A1, establishes the performance specifications and test protocols for cables concerned with power, control, and communication in construction sites. Under CPR, manufacturers must:
Notify the Reaction to Fire performance of their cables.
Supply a product DoP and apply the CE mark.
Send their products to Notified Body testing and assessment for conduction.
With that, a common classification and safety standard is brought into effect for all the EU member states.
CPR categorizes cables based on their fire performance—from Aca (non-combustible) to Fca (easily flammable).
However, only classes Cca, B2ca, and higher are recommended for modern public and commercial buildings due to their low fire propagation and smoke emission characteristics.
CPR Class | Fire Resistance | Smoke Emission (s) | Acidity (a) | Droplets (d) | Typical Application |
Aca | Non-combustible | – | – | – | Concrete-like materials |
B2ca | Very limited flame spread | s1/s2/s3 | a1/a2 | d0/d1/d2 | Hospitals, airports |
Cca | Limited flame spread | s1/s2/s3 | a1/a2 | d0/d1/d2 | Offices, schools |
Dca | Moderate flame spread | s2/s3 | a3 | d2 | Residential areas |
Eca–Fca | High flame spread | – | – | – | Non-critical installations |
■ Smoke (s), Droplet (d), and Acidity (a) Indicators
Each additional indicator refines cable performance:
s1b → Very low smoke emission, allows safe evacuation and visibility.
d0 → No flaming droplets during fire, reduces secondary ignition risk.
a1 → Minimal acidity of gases, ensuring low corrosion and less toxic fumes.
Zion Communication’s Cca-rated fire-resistant cables are engineered for compliance, durability, and performance in the most demanding environments.
CPR Class: Cca s1, d0, a1 (conducted in accordance with EN 50575:2014+A1)
Sheath Material: LSZH (Low Smoke Zero Halogen)
Insulation: Mica tape or ceramified silicone for long sustaining heat
Conductor: Solid or multi-strand copper to provide a steady current
Operating Temperature: Up to 90 °C, durable for 250 °C short circuit
Standards Compliance: EN 50200 PH120, BS 6387 CWZ (available options)
Zion Communication wire continues transmitting power throughout the fire event even as fire leads to deployment of alarms, evacuation lighting, communication wire, and fire pumps.
Selecting the correct cable for a project depends on building type, occupancy density, and risk level:
Building Type | Recommended CPR Class | Examples of Cables |
Residential buildings | Dca–Cca | General power and data wiring |
Commercial offices | Cca s1b, d0, a1 | Fire-alarm, control, data cables |
Hospitals & Airports | B2ca s1a, d0, a1 | High-safety communication cables |
Tunnels & Metro systems | B2ca/Aca | Critical evacuation routes |
Schools & Public halls | Cca s1b, d0, a1 | Low-smoke, halogen-free installation cables |
When in doubt, designers and installers should verify the cable’s DoP number and CE marking for traceable CPR certification.
Zion Communication ensures every CPR-rated cable undergoes independent third-party testing and continuous factory production control.
By maintaining full documentation—including DoP certificates, LPCB/CE approvals, and traceable batch labeling—Zion supports compliance for distributors, contractors, and end users across the EU market.
The CPR (EN 50575) regulation has transformed Europe’s approach to cable safety by standardizing fire performance criteria across all building types.
Zion Communication’s Cca s1b, d0, a1 fire-resistant cables not only comply with EU directives but also deliver long-term reliability, low smoke toxicity, and superior fire containment—protecting people, assets, and infrastructure in every critical application.
