The Tyco 4B-I 517.050.043 is a 4inch, short circuit isolator base, designed to snap-fit to the ceiling tile adapter, or screw fixed to the ceiling using the traditional method. The Tyco 4B-I is used to protect circuits that use devices that do not have built-in short circuit isolation. The 517.050.043 is compatible with the Ceiling Tile Adapter, and can potentially decrease installation time by up to 30%.
The Tyco 4B-I 517.050.043 is designed to snap-fit into the Ceiling Tile Adaptor. The base can also be screw fixed to a ceiling, electrical box, or deckhead mount in the traditional manner. A park position allows the detector to be mechanically attached to the 4B-I without making electrical connections to facilitate the testing of electronic-free bases. The base should be fixed with the park plunger faced towards the door or trafficable area. This ensures that the LED will be visible from the direction of entry, AS1670.1-2004.
With a detector mounted in the Tyco 4B-I Base, a raised rib on both the base and detector align when the detector is in the fully home position.
