INTRODUCTION
The Model HMS-SZ and HMS-DZ Manual Stations, and
their Spanish and Portuguese versions, from Siemens
Industry, Inc., are field installed addressable devices
containing advanced control panel communication
technology. This technology, which provides two-
direction communication with the control panel,
produces an Intelligent Initiating Device. The HMS-SZ/-
SE/-SP are single action; the HMS-DZ/-DE/-DP are
double action.
PROGRAMMING
Refer to Figure 1 to locate the opening on the MS cover that allows access to the
programming holes which are on the HMS printed circuit board.
To connect the HMS to the DPU Programmer/Tester,
insert the plug from the DPU cable provided with the
Programmer/Tester into the opening on the HMS as
shown in Figure 2. Because HMS devices are polarity
insensitive, the programming plug can be inserted into
the programming holes in either direction.
To prevent potential damage to the DPU DO NO

connect an HMS to the DPU until at least one wire is
removed from terminals 1 or 2 of the HMS.
Follow the instructions in the DPU Manual
(P/N 315-033260) to program the HMS to the desired
address. Record the device address on the label
located on the HMS front panel. The HMS can now
be installed and wired to the system.
OPERATION
The HMS-SZ and HMS-DZ manual stations, as well as their Spanish and Portuguese
versions, operate with the FireFinder-XLS or FS-250 Control Panels via the DLC or FS-
DLC Device Loop Card.
All HMS manual station housings have a pull down lever that locks in position after
releasing a spring loaded switch. (See Figure 4.) To indicate the manual station is
activated, the pull down lever remains down and locked until the station is physically
reset.
The HMS-DZ/-DE/-DP have an additional lever labeled
PUSH IN/EMPUJE/EMPURRE
which must be operated first.
All models are reset by opening the hinged housing cover with an Allen key and then
closing and locking the cover.
