The Rubezh MDU-1S-R3 smoke-exhaust damper control module is designed for automatic and manual control of smoke-exhaust damper actuators and fire-resisting dampers as part of the Rubezh addressable system. Operation over the R3 protocol allows the module to be integrated into the common addressable network and to control dampers directly from the central panel. The device is mandatory at facilities where the ventilation and smoke-protection system must respond to a fire alarm automatically.
Advantages
- Control of smoke-exhaust dampers and fire-resisting dampers: two types of actuators in one solution
- R3 protocol: reliable digital exchange with the central panel without false triggering
- Manual and automatic modes: control flexibility in normal and emergency situations
- Addressable integration: the module is included in the common Rubezh addressable network without additional controllers
- Damper status monitoring: the device receives feedback on the actuator position
- Compliance with requirements: support for regulatory requirements on building smoke protection
Applications
- Retail and business centers: control of smoke-exhaust systems upon a fire alarm
- Parking lots and underground structures: activation of smoke-exhaust dampers according to zoning
- Multi-story residential and administrative buildings: control of fire-resisting ventilation dampers
- Industrial facilities: integration of smoke protection into the Rubezh addressable system
- Retail and entertainment complexes: zone control of smoke-protection ventilation systems
Frequently asked questions
Can the MDU-1S-R3 control both a smoke-exhaust damper and a fire-resisting damper at the same time?
The module's assignment is defined during system programming; one module controls one actuator.
Is monitoring of the damper actuator position supported?
The module provides damper control; the availability of feedback on the actuator position depends on the type of connected damper and the system settings.
Is a separate power supply required for the module?
The power supply and connection are determined by the system design; we recommend checking with SAT Solutions engineers.
