Kramer 99-9318250 Bulk Speaker Cable 18AWG - Plenum Rated, 250'

The Kramer 99-9318250 is a 250-foot reel of 18 AWG plenum-rated (CMP) bulk speaker cable for in-wall and above-ceiling speaker installations in commercial buildings where the cable route passes through air-handling plenum spaces, requiring NEC 800 CMP fire-safety rating.

Features

• 18 AWG stranded 2-conductor speaker cable; CMP (Communications Multipurpose Cable Plenum) rated; 250-foot reel
• Plenum-rated (CMP): required by the National Electrical Code (NEC Article 800) for cable routed through air-handling ceiling plenums and HVAC return-air spaces in commercial buildings - plenum cable uses flame-retardant, low-smoke materials that meet the more stringent NEC plenum fire safety requirements vs. CMR riser-rated or CM-rated cables
• 18 AWG wire gauge is appropriate for background music and paging applications at typical distributed audio levels and run lengths (up to approximately 50 feet per conductor at 8Ω for less than 0.5dB loss); for longer runs requiring lower resistance, see the 14 AWG 99-2416300
