3.1 Structure of the System
The modular control system contains two different types of modules. Each type is equipped
with a microcomputer and is connected to the CAN bus.
Modules with complex tasks and multitasking:
• MCP Module: CENTRAL PROCESSING Module
(system control and signal processing)
• MDO Module: DISPLAY + OPERATION Module
(system status display + operation)
Modules with simple tasks without multitasking:
• MDA Module: DATA ACQUISITION Module
(measurement signal input + preliminary processing)
• MGO Module: GENERAL OUTPUT Module
(driver outputs for system messages)
• MAO Module: ANALOGUE OUTPUT Module
(0 ... 20 mA outputs)
In addition, the following modules without microcomputers and without direct access to the
CAN bus are present:
• MAI Module: ANALOGUE INPUT Module
(signal processing + digitisation for 8 measuring sites)
• MCI Module: CURRENT INPUT Module MCI 10 (signal processing for 0 ... 20 mA,
0 ... 24 V, contact)
MCI 20 (signal processing for 0 ... 20 mA)
MCI 20 BFE (BFE = Smoldering Fire
Detection)
(Signal processing for 0 ... 20 mA
especially for DF 8501, DF 8502,
DF8510 fire detectors)
• MPI Module: PASSIVE INPUT Module
(power supply + signal processing for catalytic and semiconductor sensors)
• MRO Module:RELAY OUTPUT Module
(2 models, 8/16 relays)
• MIB Module: INTERCONNECTION BOARD
• MFI Module: Fire Input Module (Power supply and signal processing for automatic
and push-button fire detectors)
• MSI-Module: Switch Input Module (Power supply and signal processing for external
switches)
• Connection modules etc.
