DM drive module for ventilation groups
One DM drive module provides a maximum of 10 A for the connection of a ventilation group.
Worked sample
Smoke and heat
extraction systems
Power requirement Drive module 10 A Switch power supplies Power modules
16 A 2 (20 A) 1 x 24 A 1 (PM)
30 A 3 (30 A) 1 x 24 A + 1 x 10 A 2 (PM + PME)
CM control module and SM sensor module
A CM control module is required in any case, as this monitors the first fire area. For each additional fire area, another SM sensor module is required.
WM weather module
A WM weather module is needed for wind direction dependent activation. Weather signals for closing during ventilation can also be added to
the central sensor input on the CM.
Casing
The casing dimension depends on the number and arrangement of modules, the number of required switch power supplies and size
of the batteries.

If only one switch power supply with 10 A is used, its space requirement on the DIN rail is added to that of the modules.
Otherwise, switch power supplies are on a separate DIN rail.
