Fire resistant alarm cable is the cable for the circuits that have to keep running after the alarm has already sounded: emergency lighting, smoke dampers, pressurisation fans and sprinkler pumps. This range is rated 300/500 V, built from 2 to 8 core, and declared to EN 50200 PH30 to PH120 with the water spray stage and to IEC 60331 - the grade that BS 8519 and EN 12101-8 specifications call up for life safety power circuits.
Fire Resistant Alarm Cable - PH30 / PH60 / PH120 Circuit Integrity per EN 50200 & IEC 60331 This circuit-integrity fire resistant alarm cable keeps emergency power and alarm signals live during fire events. Rated PH30, PH60 or PH120 to EN 50200, it maintains continuous circuit function for 30/60/120 minutes under 950°C flame, aligned with IEC 60331 and BS 5839 fire alarm installation standards. Designed for fire alarm loops, emergency lighting, smoke extraction and sprinkler control circuits. Its LSZH sheath achieves CPR B2ca / Cca classification per EN 50575, limiting smoke and toxic halogen emissions in occupied escape zones. We are the manufacturer based in Haiyan, Zhejiang, China, offering bulk supply, custom specifications and OEM service for global fire safety contractors.

BS 8519 Decides Which Circuits Need What
BS 5839-1 governs detection and alarm. It does not govern the power side. For fire-resistant power and control cable systems serving life safety, fire-fighting and other critical equipment, the governing document is BS 8519, which sorts applications into three categories by survival time: 30, 60 and 120 minutes. Read the project specification backwards from that category and the cable requirement falls out.
This is the distinction that a lot of supplier copy misses. If a buyer arrives at this page searching for fire resistant alarm cable, the useful answer is not another paragraph about mica tape. It is which category their circuit falls into, and what that does to the price per metre.

Why Fire Resistant Alarm Cable Is Critical for Life Safety
Standard alarm cable stops working the moment fire reaches it. Fire resistant alarm cable is engineered to keep critical circuits - fire detection, emergency lighting, smoke extraction, sprinkler control - running during a fire, giving occupants time to evacuate and giving fire-fighting systems time to respond. It is a legal or insurance requirement in most commercial and public buildings.
Circuit Integrity in Fire
Maintains stable power and signal transmission under direct 950°C flame exposure for 30–120 minutes.
01
EN 50200 & IEC 60331
Independently tested against globally recognised strict fire-resistance circuit integrity standards.
02
LSZH Jacket
Low-smoke, zero-halogen outer sheath, prevents dense smoke and toxic halogen gas release in fire scenarios.
03
Mica Tape Insulation
Mineral mica fire barrier protects copper conductors and preserves circuit continuity even when polymer insulation burns away.
04
Fire Resistant vs Flame Retardant - Understanding the Difference
These two terms are frequently confused but describe completely different performance. Choosing the wrong one can be fatal in a life-safety application.
| Property | Fire Resistant Cable | Flame Retardant Cable |
| What it does | Continues to carry current during a fire. | Stops flame from spreading along the cable. |
| Circuit integrity in fire | Yes - 30/60/120 minutes in direct flame. | No - circuit fails when fire reaches cable. |
| Standard | EN 50200 (PH30/60/120); IEC 60331 | CPR EN 50575 (Eca–B2ca); IEC 60332 |
| Typical use | Life-safety circuits that must operate during fire. | General building wiring, alarm signal loops. |
| Construction | Mica/mineral tape + LSZH insulation + LSZH sheath. | Flame-retardant PVC or LSZH jacket. |
| Cost | Higher - engineered for extreme conditions. | Lower. |
Quality Control & Testing
Every reel of fire resistant alarm cable undergoes full testing prior to shipment. The test scope covers fire circuit integrity, conductor DC resistance, inter-core insulation resistance and high-voltage withstand. Shielded variants also get shield continuity inspection. We retain batch samples to enable full traceability. Third-party inspection services from SGS, BV, TÜV are available on request. Our products meet BS 6387 CWZ requirements for BS 5839 fire alarm systems.
Conductor & Circuit Integrity Test
We verify conductor DC resistance and complete fire circuit integrity testing, to guarantee stable signal transmission under fire conditions for BS 5839 fire alarm installations.
Fire & Insulation Performance Test
Insulation resistance, high voltage withstand and BS 6387 fire resistance tests eliminate leakage and short-circuit risks, securing consistent circuit performance during fire emergencies.
Batch Traceability
Sample retention for every production batch supports full record tracking for quality audits, project acceptance and after-project review.
