The Siemens DB-3S is a low-profile fire detector mounting base. It is designed for installations where ceiling clearance is restricted. As a result, contractors can mount detectors in drop ceilings, plenums, and tight mechanical spaces without violating the air-gap clearance below the detector head.
The DB-3S accepts compatible Siemens detector heads via a twist-lock plug-in connection. Therefore, swapping a detector head for service does not require rewiring. Catalog reference: 595-381804.
Siemens DB-3S Key Features
- Reduced-height design for tight ceiling clearance applications
- Plug-in (twist-lock) detector head interface
- Standard electrical box mounting footprint
- Siemens part number 595-381804
Typical Applications
Use the DB-3S where a full-profile base would protrude into a return-air plenum, conflict with a drop-ceiling grid, or violate clearance below ductwork. In addition, it suits retrofits where the existing ceiling allows only a slim mounting surface.
Compatibility Note
The DB-3S is part of the legacy Siemens / FCI 11-Series detector lineup. Therefore, confirm fit against your specific Siemens detector head before ordering. Our team can verify the right base for your detector model.
