10Core 12 Core Unshield Control Cable/ Alarm Cable/Security Cable
UTP Alarm Cable Technical Data
UTP Alarm Cable refers to unshielded twisted pair cabling specifically designed for security, fire alarm, and access control systems. Unlike Ethernet UTP, these cables are optimized for low-voltage DC/analog signaling over longer distances with minimal interference. Here's a comprehensive technical breakdown.
