Fire Alarm Cables

A fire alarm cable is a cable that carries the signal between the panel and field devices in fire detection and alarm systems, with cores twisted in pairs and an aluminum foil shield with a drain wire. It is used on loop lines running from the panel to detectors, alarm push buttons, sirens and strobes. In this category, PVC-insulated J-Y(St)Y Lg, halogen-free J-H(St)H Lg and JE-H(St)H Bd types are available in sizes such as 1x2x0.80 mm, 1x2x1.5 mm² and 2x2x1.5 mm² from the Birtaş, Mekas, 2M and Reçber brands; some of them are FE180 and PH120 rated. Choose the insulation type and fire resistance class according to the project requirement, and the number of pairs and the conductor gauge according to the line length and the loop resistance permitted by the panel manufacturer. In the notation 1x2x0.80+0.40 mm, the first number indicates the number of pairs, 0.80 the conductor diameter, and the value after the plus the shield's drain wire; a value written in mm² is the conductor cross-section. PVC-insulated J-Y(St)Y and J-H(St)H cables that do not carry the FE180 marking are not fire-resistant; FE180 and PH120 rated types are made for lines that must operate in a fire.

How to choose Fire Alarm Cables

A fire alarm cable is a cable that carries the signal between the panel and field devices in fire detection and alarm systems, with cores twisted in pairs and an aluminum foil shield with a drain wire. It is used on loop lines running from the panel to detectors, alarm push buttons, sirens and strobes.

  • Clarify the circuit duty first: power distribution, control, fire safety, Ethernet or analog signal.
  • Compare conductor cross-section, core count, insulation and shielding against the installation route.
  • Switch to the proper cable family early when flex duty, oil resistance, halogen-free jacket or fire integrity is required.
