Siemens DBS729 Cerberus PRO 82-89dBA Sounder Interbase (Requires Detector Base DB72x) (S54372-F14-A1)

The Siemens DBS729 (S54372-F14-A1) is a sounder interbase with supplementary optical indication for the addressable C-NET detector bus, used with Cerberus PRO FC72x and Cerberus FIT FC361 fire control panels. It fits between a DB72x detector base and a point detector to form a single unit, and gives both an audible alarm and flashing red LEDs in the event of fire. Typical uses include hotel rooms, restrooms and offices.
