Siemens DB-HR Detector Base P/n:500-033220

The Siemens DB-HR is a low-profile, surface mounting base used on various Siemens Fire Safety conventional and addressable detectors. Siemens DB-HR is compatible with the standard, addressable type of intelligent detectors, as well as those detection devices that operate with ASAtechnology™. Additionally, Siemens DB-HR is backward compatible with the Siemens Model ‘H’-series intelligent detectors and detector-assigned FACPs.

Also, model DB-HR can also operate with Siemens’ 252-point addressable, 504-point addressable, and FireFinder® XLS fire systems. A relay output from the fire detector base for signaling other devices is provided by Model DB2-HR. The detector bases use screw-clamp contacts for electrical connections and self-wiping contacts for better reliability. Further, the bases can be use with the optional Model LK-11 detector locking kit, which contains 50 detector locks and an installation tool, to prevent unauthorized removal of the detector head.

The Siemens DB-11 Smoke Detector Base has a 6-inch (15.2 cm) diameter. The diameter for Model DB-11E is 4.5 inches (11.4 cm). Moreover, Models DB-11 and DB-11E mount on a 4’’-square, (10.2 cm) octagon or single-gang box. Model DB-11 has integral, decorative plugs to cover the outer screw holes. Standard bases for Model ’H’-series “11” and Model “121”-series conventional detectors, as well as the Model ’H’-series addressable detectors.
