protection against lint, dust, dirt, water seepage and
dripping and external condensation of non-corrosive
liquids.
Power Module
The Power Module provides regulated power to the
Point Termination Modules and active sensors. Only
one Power Module is needed per enclosure
assembly, simplifying installation and
troubleshooting.
An on-board microprocessor controls its operation
and works with the Power Open Processor or Open
Processor to ensure smooth power up and down
sequences of equipment controlled by the point
modules, even through brown-out conditions.
The Power Module contains status LEDs to indicate
24 Vac supplied from the line power supply, 24 Vdc
supplied to point modules and over voltage/under
voltage condition.
Figure 3. Two sizes of enclosure assemblies.
Enclosure Assembly
The enclosure assembly includes a backplane, rails
to which the Power Open Processor or Open
Processor, Power Module, and Point Termination
Modules snap on, a duplex receptacle and a stepdown isolation transformer.
Open Processors
The Open Processor is a microprocessor-based
multitasking platform for program execution and
communications with other field panels, FLN
devices, point modules and third-party
equipment/systems (optional). The Open Processor
scans field data, optimizes control parameters and
manages operator requests for data in seconds.
The enclosure assembly houses both electronic and
pneumatic components. The enclosure is available in
the following two sizes to allow the enclosure size
to match the point density of the application:
The Open Processor is an open communications
platform providing control of an extensive number of
building systems including:
•
24 module size
•
•
40 module size
Siemens Building Technologies, Inc. FLN. Each
Open Processor supports up to 3 trunks for a
total of 96 application specific control devices.
•
Communications drivers to non-Siemens
networks. As an option, an Open Processor can
communicate to related building system
controllers such as boilers, chillers, rooftop
units, PLCs, power meters, lighting panels, fire
alarm and life safety systems and access control
systems.
The enclosure is constructed of metal to
accommodate secure conduit fittings and protect
components against electrical transients.
The removable front door has see-through view
panels to allow the user to see the status of inputs,
outputs and override switches. The door is UL 945VA rated for fire and smoke control applications.
Enclosure assemblies allow space for easy wire
terminations. Two unswitched 115 Vac outlets are
included in each enclosure to power accessory
devices such as modems and portable operator’s
terminals.
The NEMA 12 MBC-24 and MBC-40 UL listed panel
assemblies provide control in areas requiring air-tight

The program and database information stored in the
Open Processor RAM memory is battery-backed.
This eliminates the need for time-consuming
program and database re-entry in the event of an
extended power failure. When battery replacement
is necessary, the Open Processor illuminates a
“battery low” status LED and can send an alarm
message to selected printers or terminals.
Each module is supplied with a label insert that is
customized to reflect the actual device connected to
the module. Address keys provide addressing of the
Point Termination Module to the processor and
corresponds to the point address in the database.
The firmware including the operating system is
stored in non-volatile flash memory. Flash is easily
updateable at the job site. This provides for ease of
upgrade as new firmware updates are made
available.
Brownout protection and power recovery circuitry
protects the Open Processor from power
fluctuations.
Power Open Processors
The Power Open Processor is an updated version of
the Open Processor. It employs state-of-the-art
technology to offer exceptional performance and
memory capacity. It has support for peer-to-peer
communications over industry standard TCP/IP
networks through a direct connection to 10/100
BaseT.
Figure 4. Point Termination Modules.
Point Termination Modules
The Point Termination Modules (refer to table)
support one, two, or four points. Modules are
available for analog input or output and digital input
or output point types. Any custom mixture of the
Point Termination Modules can be installed in the
enclosures.
The Point Termination Module consists of two
pieces: the electronic point module and the
termination block, which provides wire or pneumatic
tubing connections. Designed for phased
installation, the electrician wires to all the
termination blocks. The system technician installs
the module electronics during start-up, thereby
protecting electronics from harsh job site conditions.
These modules quickly and easily snap into place
without tools, and without having to re-terminate
wires for fast servicing. Modules can be snapped in
and out without powering down the field panel to
minimize any system downtime.

Optional Manual Override Simplifies
Troubleshooting
Manual override is available on digital and analog
outputs to allow the user to manually control the
position of the end device. This aids in system startup and troubleshooting to test the equipment
operation such as stroking valves and dampers. The
manual override is supervised so the central
operator is informed that an output is in the override
position. A point log report indicates override
position status. In addition, an alarm can be sent
when the point module is placed in override.
Digital output provides the following manual override
positions; on, off and automatic. Analog outputs
provide two positions; automatic and manual. In
Siemens Building Technologies, Inc.
manual override the operator can adjust the output
proportionally between full, open, and closed.
Snap-In Hardware Simplifies Service
All hardware components snap into mounting rails to
allow replacement of modules without reterminating wires or pneumatic tubing in the unlikely
event of failure. Individual Point Termination
Modules can be replaced without interrupting the
control process for any other modules; the Open
Processor continues to function and control the
other modules. The Point Termination Module, once
replaced, is automatically re-addressed by inserting
the appropriate address key into its slot.

Modular Control Panels with Application
Flexibility
The MBCs are high performance controllers with
complete flexibility to allow the owner to customize
each control panel with the exact hardware and
program for the application.
The facility manager only purchases what is needed.
For example, for monitoring applications, the control
panel can be customized with the exact number and
type of analog inputs to match the sensor devices.
For monitoring and controlling a large number of (onoff) fans or motors, digital input and output Point
Termination Modules are added.
The control program for each panel is customized to
exactly match the application. Proven Powers
Process Control Language (PPCL), a “BASIC” type
programming language, provides direct digital
control and energy management sequences to
control equipment precisely and optimize energy
usage.
For interaction between events and data on separate
systems, Open Processors equipped with various
communication drivers are utilized.
Integrated Building Block Architecture
Every MBC is capable of communications with
multiple systems. Each Power Open Processor or
Open Processor provides stand-alone control for a
family of up to 96 FLN devices. A total of 5
processors, potentially communicating with 5 other
building systems, can reside in a single MBC panel.
Powerful flexibility provides an unlimited number of
configuration possibilities. For example, two Open
Processors communicate with 192 FLN devices
while a third processor controls lighting panels and a
fourth processor communicates with a fire system
or even a network of devices utilizing a standard
protocol.
In a stand-alone configuration, the MBC can fulfill all
requirements of a BMS supervisory network
coordinator, managing operation schedules, alarms,
dialing out to other building systems, printers and
pagers, and communicating for the connected
devices.
Page 6 of 9
Global Information Access
Each MBC is equipped with two RS-232 operator
terminal ports. These ports support the connection
of a modem, simple CRT terminal, laptop PC, or
printer. Devices connected to the terminal port gain
global information access.
Multiple Operator Access
Multiple operators can access the network
simultaneously. Multiple operator access ensures
that alarms are reported to an alarm printer while an
operator accesses information from a local terminal.
When using the Ethernet BLN option, multiple
Operators may also access the controller through
concurrent Telnet sessions and/or local operator
terminal ports.
