They must keep carrying signals and power after a fire starts, while the building raises the alarm and evacuates. Being red or labelled &#8220;fire alarm&#8221; is not enough: the cable must be tested to a named standard and installed so it keeps that performance.<\/p>\n<p>This guide covers cable types, the standards used in specifications, installation, testing and common site mistakes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5e2a447 elementor-widget elementor-widget-text-editor\" data-id=\"5e2a447\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"az-keybox\"><h2>Key takeaways<\/h2><ul><li>The binding reference in Egypt is the 2026 Egyptian fire code, whose third part covers electrical, detection and alarm requirements.

In an alarm system that can silence sounders on floors the fire has not reached, cut the link between panels, or lose a control signal such as an AHU shutdown.<\/p>\n<p>This is the idea behind circuit integrity: a cable keeps carrying its signal or current for a set time while exposed to flame. BS 5839-1 recommends fire-resisting cable for critical signal paths and the panel mains supply. The designer decides which circuits must stay live.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-385e0e5 elementor-widget

Enhanced cable must achieve PH120 to BS EN 50200 and pass BS 8434-2, which includes water spray. The minimum conductor size stays at 1 mm\u00b2. Red is the preferred colour for fire alarm cables, and black or white cables should not be used.<\/p>\n<h3>BS EN 50200 and BS 7629-1<\/h3>\n<p>BS EN 50200 (2015 edition) is a test method, not a product specification. It covers cables up to 20 mm diameter and 600\/1000 V, exposed to direct flame at a nominal 842 \u00b0C. BS 7629-1 is a British product specification for 300\/500 V fire-resistant screened cables with low emission of smoke and corrosive gases.<\/p>\n<h3>IEC 60331<\/h3>\n<p>The IEC 60331 series tests circuit integrity of cables under fire.

The General Directorate of Civil Protection (Ministry of Interior) reviews drawings and systems before occupancy. The project specification usually adopts one reference set for cables, British or American. Do not mix them in one system.

With plastic clips or unsupported plastic trunking, the run can drop when the clips melt, before the cable fails. Fire alarm standards therefore call for fixings and supports that survive the fire for the same time, usually metal. BS 7671 also requires wiring to be supported against premature collapse in a fire, so hanging cables do not trap firefighters.<\/p>\n<h3>Segregation from other cables<\/h3>\n<p>Keep fire alarm cables apart from power and other systems. The NEC, for example, asks for at least 2 inches (about 50 mm) between fire alarm cables and power conductors outside raceways, or a listed barrier where they share a raceway. Under British references, follow BS 5839-1 and BS 7671.<\/p>\n<h3>Loops, joints and penetrations<\/h3>\n<ul><li>In an addressable system, route the outgoing and return legs of a loop separately where possible, so a single incident cannot cut both.<\/li><li>Minimise joints.

Start with circuit function, survival time and the adopted reference set, then the panel manufacturer&#8217;s requirements and the cable&#8217;s test certificate.
