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.

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.

WIRING
INSTALLATION Distribute the manual station boxes throughout the protected area so that they
are unobstructed, readily accessible, and located in the normal exit path. Place the
manual station according to the regulations of the authorities having jurisdiction.
Surface Mounting Mount the backplate to a Model SB-5R Backbox as shown in Figure 4.
Flush Mounting Mount the backplate to a user supplied single gang switchbox.
Do not overtighten the screws. Overtightening may distort the backplate.

NOTES:
1. Recommended wire sizes:
18 AWG minimum, 14 AWG maximum
2. Wire larger than 14 AWG can damage the connector.
3. When using shielded cable without metal raceway or with
nonmetallic raceway, the shields should be terminated at the device
ground terminal. If the device box is already grounded by another
means, such as being mounted to a grounded structure, the wire
shields should be continuous and must be grounded solely at the point
of origin; for example, at the control panel.
4. When using shielded cable with metal raceway, the wiring shields
shall be continuous and grounded solely at the point of origin.The
device ground terminal shall be connected to the grounded device box.
5. When using metal raceway without shielded cable, connect the
device ground terminal to the grounded device box.
6. Metal raceway should be thoroughly grounded throughout the system.
7. In supervisory: All HMS manual stations draw 1mA.
8. All HMS manual stations are polarity insensitive devices. Line 1 and
Line 2 can be either line of the DLC or FS-DLC loop.
