Securiflex Alarm Cable | TCCA Type 3, 4 Core, 100m, LSF | White

FAQs

When do I need 4 core LSF instead of 4 core PVC?

Choose 4 core LSF when building regulations or fire safety policies require low smoke and fume properties, even for simple installations. This is typical in public buildings (schools, care homes, small offices), enclosed public spaces, or anywhere where occupant safety regulations mandate LSF construction. If you’re installing a basic 4-circuit system in a school classroom, small retail unit in a shopping centre, or care facility where LSF is required but you don’t need 6 or 8 cores, this cable provides the necessary fire safety at minimum cost and maximum installation ease.

What are the advantages of the ultra-compact 3.50mm diameter with LSF?

This is the smallest fire-safe alarm cable available, combining the LSF safety benefits with maximum installation flexibility. The 3.50mm diameter means you get enhanced fire protection without sacrificing the practical advantages of a compact cable – it fits through extremely tight spaces, requires minimal conduit capacity, is easier to conceal in finished spaces, and causes less visual impact in public areas. For retrofit installations in schools or care homes where you need to add fire-safe alarm cables to existing buildings, this compact size is invaluable.

Is 4 core sufficient for public building alarm systems?

For basic, straightforward installations, yes. Many simple public building applications only require 4 cores – connecting individual sensors to junction boxes, basic single-zone systems in small rooms or areas, individual device connections like panic buttons or smoke detectors, or simple supplementary circuits. However, if you’re installing a multi-zone system or need future expansion capability, consider 6 or 8 core options. The 4 core LSF is perfect when you know your system design is straightforward and you want to minimize costs while meeting fire safety requirements.

How does this compare to 6 core LSF cable?

The 4 core version offers cost savings (typically 15-20% less than 6 core) and an even more compact installation footprint, while maintaining identical LSF fire safety properties and Eca CPR classification. If your installation only needs 4 circuits, you save money without compromising on fire safety. However, the 6 core version (with Red, Black, Blue, Yellow, Green, White) provides more flexibility for system design and future modifications. Choose 4 core when you’re certain about your circuit requirements and want maximum economy and compactness.

Where are typical applications for this cable?

Ideal for: individual classroom alarm systems in schools, basic sensor circuits in care home bedrooms, simple detection zones in small retail units within shopping centres, individual panic button connections in public facilities, basic single-zone systems in small offices or meeting rooms, connecting individual devices in public buildings where LSF is mandated, and retrofit installations in existing public buildings where space is limited but fire safety is essential. Any situation requiring LSF fire properties for simple 4-wire circuits where larger cables would be unnecessary and wasteful.

Does the compact size affect fire safety performance?

Not at all. Despite its ultra-compact 3.50mm diameter, this cable achieves the same Eca CPR classification and LSF fire performance as larger LSF cables. The low smoke and fume properties are determined by the jacket material composition, not the cable diameter. You get full LSF fire safety benefits – minimal smoke production and no toxic gas emission – in the smallest, most installation-friendly package available. It’s the perfect example of not having to choose between fire safety and practical installation advantages.
