While it is a shielded alarm cable, it has a wide range of applications, including smoke alarms, smoke detectors, voice communications, microprocessor-controlled systems, pull boxes (fire alarm signals), burglar alarms, and other low voltage applications.
When it comes to fire alarm systems in particular, fire alarm circuits control and power applications such as safety functions, elevator capture and shutdown, damper control, and door release.
According to NEC Articles 760 and 725, there are two types of fire alarm system circuits: power restricted and non-power limited.
Power Limited Fire Alarm Wires typically work at 24 volts DC, whereas non-power limited alarm shield cables run at 120 volts AC. Non-power limited alarm shield cables are typically obsolete since low-voltage alarm shield cable offers greater benefits.
Xingfa, a speaker cable factory, produces speaker cable, including red-and-black and transparent-jacket product families, for buyers sourcing wiring for audio installations.
Rather than choosing by appearance alone, establish the amplifier-to-speaker distance and the conductor size required for the intended load. Jacket style and packing can then be discussed around that electrical requirement.
Ask Xingfa for speaker cable information matched to your planned runs.
