Product Quality

We carry a diverse range of top-notch alarm cables to fulfill your requirements. Our bulk security cables are available with both riser and plenum rated jackets. Prior to purchasing alarm cable, verify compliance with building code requirements. The alarm cables also feature print legends, enabling swift identification of each cable's application. With time being precious, the installation convenience of our security alarm cables makes them the preferred choice for various 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, set up, and termination time is shorter.

Why Plenum?

A plenum space is the open area above the drop ceiling or below the floor that is used for air circulation in buildings. This could be a problem if there is ever a fire. Using non-plenum cables in a plenum space can spread fire and toxic smoke throughout a building. Plenum cable uses a flame-retardant jacket that is made of special plastics to prevent the release of harmful smoke. Plenum cable is mostly used in commercial applications such as schools and hospital buildings that house a large population of people. It also is required in most multi-floor business buildings with large plenum space areas.
