INTRODUCTION The Model HMS-2S/-SA Manual Station from Siemens

Industry, Inc., is a field installed addressable device
containing advanced control panel communication
technology. This technology, which provides two­direction communication with the control panel,
produces an Intelligent Initiating Device.

programming holes which are on the HMS printed
circuit board.

PROGRAMMING

To connect the HMS to the DPU Programmer/Tester,

POINTS

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 NOT
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 manual station operates with the FireFinder-XLS Control Panel via the DLC

Device Loop Card.

The HMS-2S/-SA 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 HMS-2S/-SA manual station has a set of normally closed auxiliary contacts
which are available for releasing door holders and magnetic door locks.

The HMS-2S has a keyswitch which can activate a second address.

The unit is reset by opening the hinged housing cover with an Allen key and then
closing and locking the cover, or by returning the keyswitch to its original position.

8. The HMS-2S / HMS-SA is a polarity insensitive device. Line 1 and Line 2
can be either line of the loop.

The use of limited energy cable is not allowed.

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 as shown in Figure 4.

Do not overtighten the screws. Overtightening may distort the backplate.
