Applications
A broad range of applications exist for bulk plenum security alarm cabling. It is widely used with security systems, intercom systems, sound/audio systems, and power-limited controls in commercial settings such as schools, universities, hospitals, airports, government buildings, train and transportation centers, stadiums, and arenas. Since this security cable has multiple conductors under one jacket, the preparation, setup, and termination time is shorter.
