The Model DB-HR from Siemens Industry, Inc. is a polarity insensitive detector
base and works with HFP-11, HFPT-11, HFPO-11, SFP-11*, SFPT-11* and SFPO-
11* detectors only. Detectors should be interconnected as shown in Figure 1
and wired to the DLC (refer to DLC Installation Instructions, P/N 315-033090), FS-
DLC (refer to FS-250 Installation, Operation and Maintenance Manual, P/N 315-

Manual, P/N 315-049589C), as applicable. Line 1 and Line 2 can be either line of
the loop.
Note any limitations on the number of detectors and restrictions
on the use of remote devices permitted for each circuit.
