Single Action Manual Station

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 two­direction communication with the control panel,
produces an Intelligent Initiating Device. The SMS-S
is single action.

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 insensi­tive, 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.

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.

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.

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 MC-5 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.
