Page 3: Introduction
1. INTRODUCTION _________________________________________________ This operation and maintenance manual (OMM) provides information on applications, design, operation, installation and maintenance of mcr EXi-F smoke control system for escape routes. This manual also includes additional information on operating conditions, maintenance and warranty terms and conditions.
Page 4: System Applications
EXi-F system can be used in staircases with protected lobbies and is compatible with systems including at least one pressure transmitter per protected area. mcr EXi-F system consists of a configured set of devices preventing smoke ingress to the protected area by increasing pressure. Constant...
Page 5: Operation
The system is managed by mcr Omega control unit (CU) including all the required components (e.g. mcr ICR positive pressure regulator). Positive-pressure mcr EXi-F system is activated automatically via SAP signal or manually via CU or the manual control panel. After detecting the fire in the building, the air dampers of the air supply units are activated, and the air supply unit is activated with a delay (necessary to open the shut-off dampers).

Page 13: Mcr Exi-Fair Supply Units
EXi-F air supply units include mcr Monsun E1 series axial fans in a box type housing. Air supply fans are characterized by high efficiency at low pressures. The task of the fans is to transport the appropriate amount of air to ensure that the design requirements are met.
Page 14 For vertical installation indoors, the unit is mounted on the supporting structure and connected to the air supply system in accordance with the design requirements. mcr EXI-F air supply units include multi-blade dampers with actuator. The rotary mechanism of the damper include gears and bearings or steel rods.
