MBZ300
6
Functions and properties
2.2 Properties
à
Control of electromotive 24 V DC drives for smoke and heat extraction in the event of fire
à
Controlling of a controlled natural ventilation (if necessary also triggering of pressure-gas generators and
hold-open magnets)
à
Processing of triggering signals of manual and automatic fire detectors and fire alarm systems
à
Manual and automatic ventilation control (via vent switches, wind-rain sensors, room temperature sensor etc.)
à
Forwarding of all significant operating statuses to external evaluation components
à
Possibility for maintenance, configuration and update with PC software for Windows© (via USB port)
à
Integration in an external BUS system (e.g. CAN)
à
NRA/RWA operation using rechargeable batteries in the event of main power supply outage
à
Line monitoring of all the connected manual and automatic detectors as well as of the drive lines
à
Visual operation and malfunction messages for fast error localisation
à
Digital recording of important operating statuses and service settings
à
Internal BUS system for modular equipping:
à
Power module
PM
for controlling and monitoring the mains and battery voltage as well as charging circuit
and battery
à
Power module extension
PME
for controlling and monitoring more than one switching power supply unit
(max. 3 switching power supply units 24 A for 72 A)
à
Control module
CM
for connecting manual and automatic fire detectors as well as external EMERGEN-
CY-OPEN triggering signals; with USB port
à
Sensor module
SM
with the same connection possibilities as control module
CM
. The sensor module re-
quires a control module to be present
à
Drive module
DM
for 10 A max. drive current for connection of 24 V DC drives, various push buttons and
control units. Pressure-gas generators or hold-open magnets can be triggered or supplied by correspond-
ing programming
à
Weather module
WM
for operating wind and rain sensors and wind-direction-dependent opening and
closing of smoke extraction units in the case of fire
à
Relay module
ERM
for the notification of error and operating statuses via 6 signal relays
à
USB interface for configuring and controlling the control panel via software, for updates and for storing user
information
à
Thermal detector for temperature-dependent battery charging
All the units are located in a lockable surface-mounted housing made of painted sheet steel (RAL 7035) with lock-
ing insert (two-way key bit, 3 mm) in IP rating 30. The housing dimensions depend on the version and equipment
of the control panel.
2.3 GEZE MBZ300 modular principle
Hardware configuration
à
The modules can be installed on a standard top-hat rail (TS 35). After correct connection the module is recog-
nised immediately and integrated automatically into the system via the BUS. Faults and errors during connec-
tion are indicated through rapid flashing of the status displays or through the fault display (see chapter 5.1.5).
Software configuration
à
Fire sections and ventilator groups can be configured in varied ways thanks to the modular system.
à
Thanks to the possibilities of the software configuration and the extensive area of application of the modules,
special installations in the control panel are hardly necessary for special applications.
2.4 Components of the MBZ300 control panel
2.4.1 Power supply (depending on the version)
à
1 switching power supply unit 10 A and 2 emergency-power batteries 12 V (minimum equipment)
à
1 switching power supply unit 24 A and 2 emergency-power batteries 12 V
à
2 switching power supply units 24 A (= 48 A) and 2 emergency-power batteries 12 V
à
3 switching power supply units 24 A (= 72 A) and 2 emergency-power batteries 12 V (maximum equipment)
