These alarm signal cables carry low-voltage signals and auxiliary power in civil and industrial safety installations. The range covers shielded and unshielded PVC constructions with stranded bare copper conductors, 0.22 mm² signal cores and optional 0.50 mm² or 0.75 mm² feeding cores. Start by deciding whether the cable route needs protection from electrical interference.
The range has two representative constructions: choose the shielded cable for routes where interference control is required, or the unshielded cable for suitable routes where shielding is not specified. Both use stranded bare copper conductors, white PVC insulation and sheath, CPR-Eca classification, and multiple signal-only or signal-plus-feeding formations.
SHIELDED · CPR-Eca
Uses PET foil, aluminum/PET foil and a tinned-copper drain wire for routes that require shielding. Available in 0.22 mm² signal formations and mixed 0.22/0.50/0.75 mm² formations. Confirm the exact core formation and cable diameter for the project.

A simpler construction for routes where a shield is not required by the system design. It offers the same listed conductor-size families and PVC sheath. Confirm route conditions, core formation and installation requirements before specifying it.
View Product Details →Make the shielding decision first, then select the required signal and feeding conductors. The final construction must match the equipment design, route conditions and local installation requirements.
Choose the shielded alarm cable when the design calls for interference control. Its foil layers and drain wire provide the shield structure, but correct routing, termination and grounding still need to be defined by the system designer.
Use 2–12 × 0.22 mm² formations for signal-only layouts. Mixed formations add two 0.50 mm² or 0.75 mm² feeding conductors alongside 2–12 signal conductors of 0.22 mm². Select the formation from the equipment current, voltage-drop and circuit-design requirements.
Both product pages list 300 V operating voltage, with a maximum voltage to ground of 400 V AC, an operating range of -30 °C to +80 °C, and an installation range of -5 °C to +50 °C. These limits do not replace project-specific electrical and regulatory checks.
Plan for a minimum bending radius of 10 times the cable diameter. Because the listed outer diameter changes with the selected formation and shielding, confirm the exact product code before calculating tray, conduit or cabinet space.
The electrical ratings and conductor-size families are shared; the practical choice is whether the route requires a foil shield and drain wire. Confirm the exact formation, outer diameter and project compliance before ordering.
| Product | Shield Structure | Conductor Formations | Operating Limits | When to Consider |
|---|---|---|---|---|
| Shielded CPR-Eca | PET foil, aluminum/PET foil, 0.4 mm tinned-copper drain wire | 2–12 × 0.22 mm²; mixed 2 × 0.50 or 0.75 mm² plus 2–12 × 0.22 mm² | 300 V; max. 400 V AC to ground; -30 °C to +80 °C | Routes where the system design requires interference control |
| Unshielded CPR-Eca | No shield listed | 2–12 × 0.22 mm²; mixed 2 × 0.50 or 0.75 mm² plus 2–12 × 0.22 mm² | 300 V; max. 400 V AC to ground; -30 °C to +80 °C | Suitable routes where shielding is not required by the approved design |
These products fit low-voltage alarm, signaling and auxiliary-control circuits in civil and industrial safety installations. They should not be treated as a universal substitute for fire-resistant, data-network or outdoor-rated cable.
Use them between compatible low-voltage alarm equipment when the selected conductor formation and shielding match the system design. Verify equipment terminals, circuit load and local installation rules.
Mixed formations combine 0.22 mm² signal conductors with two larger 0.50 mm² or 0.75 mm² feeding conductors. Confirm current demand and voltage drop rather than selecting only by core count.
CPR-Eca classification does not by itself confirm fire resistance or circuit integrity. For regulated fire alarm or evacuation circuits, use the cable type and certification required by the approved design and applicable code.
Do not assume outdoor exposure, direct burial, Ethernet, RS-485 or other protocol performance from the alarm-cable name. Specify a purpose-rated product when the route or protocol requires it.
It is a multicore low-voltage cable used to carry alarm, signaling and auxiliary-control circuits. The correct version depends on shielding, conductor formation, route conditions and the approved system design.
The shielded version adds foil layers and a drain wire to support interference control; the unshielded version does not list this structure. A shield only works as intended when routing, termination and grounding are correctly designed.
Yes, selected mixed formations include two 0.50 mm² or 0.75 mm² feeding conductors plus 0.22 mm² signal conductors. Confirm circuit load, voltage drop and equipment requirements for the exact formation.
No. CPR-Eca is a reaction-to-fire classification and does not automatically establish fire resistance or circuit integrity. Use a specifically approved fire-resistant cable when the project requires continued operation during fire.
Provide the shielding requirement, number of signal cores, any feeding-core size, route temperature, minimum bend space, required length and applicable standards. These details determine the exact formation and outer diameter.
