All Building Entrance Terminals (BET) perform the same basic function. They take copper outside plant (OSP) voice/data lines (pairs) that are exposed to the possibility of surges of unexpected voltage and send those surges to ground. They come in a variety or pair count sizes, input/output connection types and security and element protection. Follow these five basic steps when choosing the right BET for the job. Step One - Application: Voice and low-speed data applications use standard BETs. High-speed networks and sensitive data equipment require enhanced BETs (see page 26) Step Two - Pair Count: These units follow the same basic pair counts of the PE89 Outside Plant Cable 6, 12, 25, 50, 100, 200, 300 on up to 2400 pair. Larger applications will require multiple terminals. Step Three - Input/output Termination: National Electric Code (NEC) requires that the OSP Cable must be connected to a UL497 Approved Primary Building Entrance Terminal within 50’ (15 meters) of entering the building. There are several varieties of termination styles to choose from. 7 66 Block Quick Clip/110 Connectors - Both single punch down methods. BIX Connector - Canadian Standard single punch down method. 710/MS2 Connectors - Used for predominantly larger projects these units utilizes special tools that punch down 25 pair at a time. Stub Termination - The BET has a factory installed 25, 50 or 100’ pre terminated tail on the input side of the unit. (custom lengths are available upon request) RJ-21 Connector - This is a 25 Pair Telco Connector that comes in both Male and Female versions. Step Four - Cover and Splice Chamber Options: Again you will have several different options to choose from depending on the application and the level of security or element protection required. Dust Cover - Provides basic protection that covers the Input/output and modules Security Cover - Provides total enclosure and is equipped with either a can bolt or other locking device for security reasons. Splice Chamber - A totally enclosed compartment on the input side of the BET to secure the OSP jell filled cable from the rest of the application. Outdoor Rated NEMA 4X - Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hosedirected water; and will be undamaged by the external formation of ice on the enclosure. Step Five - Choose the correct Surge Protection Module (ordered separately see pg 29)
