The type BR24-F-ST actuator is intended for the operation of smoke dampers in ventilation and air-conditioning systems.
The modification and mounting of the actuator to the smoke damper are made by the manufacturer of the damper. For this reason the actuator is only supplied directly to fire and smoke damper manufacturers. The manufacturer then bearsoverall responsibility for proper functioningof the damper.

There are two fixed microswitches in the actuator BR24-F-ST for indicating the end positions of the damper. Intermediate positions of the damper blade are shown by a mechanical indicator.

Manual operation
The damper can be operated manually by means of a crank handle. The functional check of the damper is therefore possible by simple means.

The actuator BR24-F-ST is compatible with the control unit for pulse triggering BSIA24-48(-R).
