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 INSTRUCTIONS
Refer to Figure 1 to locate the opening on the HMS 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 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.
WIRING
Figure 3
HMS-2S / HMS-SA Wiring Information
NOTES:
-
Recommended wire sizes: 18 AWG minimum, 14 AWG maximum
-
Wire larger than 14 AWG can damage the connector.
-
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.
-
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.
-
When using metal raceway without shielded cable, connect the device ground terminal to the grounded device box.
-
Metal raceway should be thoroughly grounded throughout the system.
-
Addressable Device Loop ratings:
Voltage: 31V max.
18V min. (pulsing)
Current maximum: 1mA
In supervisory: HMS-2S / HMS-SA draws 1mA. -
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.
ELECTRICAL RATINGS
