A comprehensive technical guide to British Standard BS5839 Part 1 fire resistant cables for building safety systems.
英國標準 BS5839 第一部分防火電纜技術全面指南，適用於建築安全系統。
Introduction to BS5839-1 Standard BS5839-1 標準介紹
British Standard BS5839-1 is a code of practice for the design, commissioning, installation, and maintenance of fire detection and fire alarm systems in non-domestic buildings. This standard provides comprehensive recommendations for the planning and implementation of fire safety systems, ensuring that interconnections between fire alarm components operate correctly for an appropriate duration during evacuation scenarios.
英國標準 BS5839-1 是非住宅建築中火災探測和火災警報系統的設計、調試、安裝和維護實務規範。該標準為火災安全系統的規劃和實施提供全面建議，確保火災警報組件之間的互連在疏散情況下能夠正常運行適當的時間。
The standard covers fire protection systems including smoke control, emergency lighting, automatic door release, fire alarm systems, voice alarm systems, fire extinguishing systems, and associated safety measures such as elevator grounding, valve closing, and air handling shutdowns.
該標準涵蓋的消防系統包括煙霧控制、緊急照明、自動門釋放、火災警報系統、語音警報系統、滅火系統，以及相關安全措施如電梯接地、閥門關閉和空氣處理關閉。
Fire Resistance Classifications 耐火等級分類
BS5839 cable standard defines two primary grades of fire resistance: Standard Grade and Enhanced Grade. These classifications determine the level of fire resistance that cables must provide during emergency situations.
BS5839 電纜標準定義了兩種主要耐火等級：標準級和增強級。這些分類決定了電纜在緊急情況下必須提供的耐火級別。
Standard Grade (Clause 26.2d) 標準級
PH30 classification per BS EN 50200 with 30 minutes survival time per Annex E.
根據 BS EN 50200 達到 PH30 分類，並按附錄 E 具有 30 分鐘存活時間。
Enhanced Grade (Clause 26.2e) 增強級
PH120 classification per BS EN 50200 with 120 minutes survival time per BS8434-2.
根據 BS EN 50200 達到 PH120 分類，並按 BS8434-2 具有 120 分鐘存活時間。
Enhanced Grade Recommended Applications | 增強級推薦應用場景
Enhanced fire resistant cables are recommended for: unsprinklered buildings with four or more evacuation phases; buildings greater than 30m in height; premises where fire in one area could affect cables serving remote occupied areas; and any setting where fire risk assessment indicates enhanced protection is required.
增強耐火電纜推薦用於：具有四個或更多疏散階段的無噴淋建築；高度超過 30 米的建築；一個區域的火災可能影響服務於遠程有人區域電纜的場所；以及火災風險評估表明需要增強保護的任何環境。
