Compact control units RZM240 / RZM480

For large projects and special structures

  • Simple and flexible layout in accordance with the modular principle. All modules are connected to one another by means of modern, internal BUS technology.
  • Variable expansion options for alarm and ventilation groups through top-hat rail installation
  • Quick and simple configuration using the software
  • Comfortable and clear status, error and fault signalling via LED indicators
  • Wide range of adjustment and application functions:
    • Automatic ventilation <CLOSE> with programmable time selection
    • Dead man's switch function in <OPEN> and <CLOSE> direction
    • Runtime limitation for ventilation, adjustable
    • Selection of the running direction in the event of an alarm
  • Simple connection option of multiple central control units to a large control system via BUS
  • Connection of wind/rain detector without auxiliary module, with integrated evaluation and wind measurement (adjustable wind speed)
  • Easy to install, commission and maintain
  • Control device VdS-tested in accordance with EN 12101-9
  • Power supply VdS-tested in accordance with EN 12101-10

Features / configuration

  • The basic RZM module central control unit consists of:
  • 1 x power module (PM)
  • 1 x control module (CM)
  • 1 x drive module (DM)
  • A drive module (DM) is required for each drive line (ventilation group). Another drive module (DM) is required for each additional drive line
  • The first fire section is monitored by the control module (CM). A separate sensor module (SM) is required for each additional fire section
  • It is possible to connect up to 64 modules
