Module for controlling a smoke exhaust damper flap or a fire-retardant damper.
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.
