INTRODUCTION The Model SMS-S Manual Station from Siemens
Building Technologies, Inc. is an addressable device
containing advanced control panel communication
technology. This technology, which provides two-
direction communication with the control panel,
produces an Intelligent Initiating Device. The SMS-S
is single action.
PROGRAMMING Refer to Figure 1 to locate the opening on the SMS cover that allows access to the
programming holes which are on the SMS printed circuit board.
To connect the SMS to the SDPU Programmer/Tester, insert the plug from the SDPU
cable provided with the Programmer/Tester into the opening on the SMS as shown
in Figure 2. Because SMS devices are polarity insensi-
tive, the programming plug can be inserted into the
programming holes in either direction.
To prevent potential damage to the SDPU DO NOT
connect an SMS to the SDPU until at least one wire is
removed from terminals 1 or 2 of the SMS.
Follow the instructions in the SDPU Manual
(P/N 315-033260C) to program the SMS to the desired
address. Record the device address on the label
located on the SMS front panel. The SMS can now
be installed and wired to the system.
OPERATION The SMS-S manual station operates with the FS-250C Control Panel via the FDLC
Device Loop Card.
The SMS-S manual station housing has 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 SMS-S is reset by opening the hinged housing cover with an Allen key and then
closing and locking the cover.

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. CX-2 Addressable Device Loop ratings:
Voltage: 31V max.
18V min. (pulsing)
Current maximum: 1mA
8. The SMS-S is a polarity insensitive device. Line 1 and Line 2 can be either
line of the FDLC or loop.
