Product Overview

The detector bases are low-profile, surface mounting bases used with various Siemens – Fire Safety conventional and addressable detectors. Model DB2-HR, which is a redesign of Model DB-HR, is compatible with the standard, addressable type of intelligent detectors, as well as the multi-criteria detection devices utilizing the patented ASAtechnology.TM

Model DB2-HR supports operation with Siemens’ 50-point addressable; 252-point addressable; 504-point addressable, and FireFinder® XLS / Modular 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 increased reliability. Further, the bases can be used 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.

Specifications

Models DB-11 and DB-11E are standard bases for Model ’H’-series “11” and Model “121”-series conventional detectors. Model DB-11 has a 6’’ (15.2 cm) diameter, and 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. However, Model DB2-HR mounts on a double-gang, 4-inch (10.2 cm.) square electrical box.
