Model 'H'-series intelligent detectors
 Models DB-11 and DB-11E mount on a 4-inch square,
octagon or single-gang electrical box
 Model DB-11 has plugs to cover the outer-mounting screw holes
 Model DB2-HR mounts on a 4’’-square, double-
gang electrical box
Product Overview
The detector bases are low-profile, surface-mounting bases
used on 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 those detection devices
that operate with ASAtechnology
™.
Additionally, Model DB2-HR is backward compatible with
the Siemens Model 'H'-series intelligent detectors and
detector-assigned FACPs. Model DB2-HR can also operate
with Siemens' 50-point addressable; 252-point
addressable; 504-point addressable, and FireFinder

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 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 the standard bases for
Model ’H’-series “11” and Model “121”-series conventional
detectors, as well as the Model ’H’-series addressable
detectors. Model DB-11 has a 6-inch (15.2 cm) diameter.
The diameter for Model DB-11E is 4.5 inches (11.4 cm).
Specifications ─ (continued)
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.
Dimensions
Note: Model DB-11E base detector has a diameter dimension of 4.5’’ (11.4 cm.).

Notes: The Module Barrier (shown to the right) must be used when Model DB2-HR relay contacts are
connected to non-power-limited circuits. Break apart the barrier to the correct size and shape
for either the 4-inch square or double-gang box. Install the barrier diagonally into the back box
to create two (2), separate compartments with the back box, in order to separate the wires.
