This Solid Unshielded CMR Fire Alarm Cable is a premium low-voltage wire designed for critical fire alarm, security, and communication systems, including burglar alarms, public address systems, intercoms, telephone stations, access control, instrumentation, nurse call, and other power-limited low-voltage circuits. Built with 100% solid pure copper conductors, it ensures maximum conductivity and reliable signal transmission for uninterrupted system performance. Its CMR/CL3 flame-retardant jacket provides reliable fire protection in riser and general-use spaces, minimizing smoke and toxic emissions. The UV- and moisture-resistant jacket allows safe indoor and outdoor use, though the cable is not suitable for direct burial or long-term immersion. Designed for ease of installation, the round, smooth jacket with rip cord allows effortless pulling through corners and conduit. Fully UL/ETL certified and RoHS-compliant, this solid unshielded CMR cable combines optimal copper performance with rigorous safety standards for commercial and residential low-voltage circuits.
