Product Q&A

Q:Is this 4-core cable suitable for addressable fire alarm detector loops?

Yes, the 4-core configuration is designed for addressable fire alarm systems, supporting loop power, bi-directional data communication and circuit isolation for intelligent detectors.

Q:Does this cable meet building fire codes for life safety systems?

Yes, the UL 21576 certification and VW-1/FT1/FT2 flame retardant rating meet standard commercial and residential building fire codes for life safety systems.

Q:What is the maximum loop length for addressable fire alarm systems?

For typical addressable fire alarm loops at 12-24V DC, this 24AWG cable supports loop lengths up to 1000 meters depending on device count and current draw.

Q:Is this cable suitable for installation in ceiling plenums?

This standard version is suitable for conduit installation in plenum spaces. For direct plenum exposure without conduit, we recommend our specialized plenum-rated fire alarm cable variants.

Q:Do you offer this cable in red jacket standard for fire alarm systems?

Yes, red jacket is the industry standard for fire alarm cables. Custom colors are also available for specialized system requirements.
