B24, B230 – Open/Close actuators
Application
Open/Close actuators for the opening and closure of smoke control dampers, with automatic (AA) or manual release (MA).
With integral limit switches for capturing the end positions
Override control for up to 25 minutes
Ambient temperature for normal operation: –30 to 50 °C, up to 95% rh, no condensation (EN 60730-1)
Two integral limit switches with volt-free contacts can indicate the damper blade position (OPEN and CLOSED)
The connecting cables of the 24 V actuator are fitted with plugs, which ensure quick and easy connection to the TROX AS-i bus system
The connecting cable of the 230 V AC actuator is fitted with wire end ferrules
Variants
B24
24 V AC/DC supply voltage
BE24-12-ST TR: Torque 40 Nm
BLE24-ST TR: Torque 15 Nm
B230
Supply voltage 230 V AC
BE230-12 TR: Torque 40 Nm
BLE230 TR: Torque 15 Nm
The torque required to operate the smoke control damper depends on the size which is why the actuator type cannot be chosen freely.
Installation information
Feeding the electric connecting cable through the actuator encasing requires a drilled hole of the exact size (Ø max. + 1 mm)
A wire clamping bracket is required
For details on maintenance and inspection refer to the installation and operating manual
