(CMC, IoT interface, PDU)
The Computer Multi Control (CMC) is an alarm system for control, network and
server cabinets. It monitors temperatures, humidity, inflow, smoke, energy and many
other physical environmental parameters. The CMC III has a CAN bus interface to
which various CAN bus sensors can be connected. The system can be addressed
via the network using a standard browser as well as with the most common network
protocols.
As an alternative to the Rittal CMC, the Rittal IoT interface or various PDUs can also
perform these functions.
The system DET-AC III Master also has two CAN bus interfaces (Fig. 50/16) through
which the system can be connected directly to various monitoring systems from
Rittal (CMC, IoT interface, PDU)

System” on page 32 .
The CMC-TC is the predecessor to the CMC III and does not have a CAN bus inter-
face. The three states “Failure” (Fig. 50/6), “Fire alarm” (Fig. 50/7) and “Pre-alarm”
(Fig. 50/8) can be queried via the RJ12 connectors (Fig. 50) using a
CMC-TC I/O Unit.
6.3.4 External fill level monitoring and external tank
The option of external fill level monitoring and selection of an external tank exists
only for the aspirating smoke detection system EFD III. The aspirating smoke detec-
tion system EFD III provides the option of triggering an external extinguishing agent
container in the event of a fire. Moreover, the extinguishing agent fill level of the
external extinguishing agent container can be monitored with the aspirating smoke
detection system EFD III.
