Reliable protection in case of emergency
Our drives for smoke and fire protection offer technology at the highest level. Compliance with standards and classifications is as important as it is necessary - for a safe feeling.
In the event of a fire, a smoke curtain or fire protection closure must be rendered ineffective in a controlled manner and automatically reach the functional position. This self-closing feature, combined with the integrated control of the closing speed, makes fire protection solutions even safer. Whether smoke protection closure, fire protection closure or fire protection closure - the application is proven and certified.
Our self-closing drives, which bring the fire protection closure into the functional position without auxiliary power - also known as fail-safe tube motors - are available in various designs and sizes.
Fire protection drives - from Becker.
Our tubular drives with the right locking device for your application:
- Smoke barrier
- Fire protection barrier
- Fire protection curtain
- Smoke protection curtain
Your safety is what drives us
Tubular actuator with absolute encoder
Winner of the R+T Innovation Award Gold 2024
Becker-Antriebe presents the latest generation of tubular drives with absolute value encoders for smoke and fire protection applications. This combines innovation and proven technology for a new level of safety and is ready for the structural and normative requirements of tomorrow.
The advantages at a glance:
- Increase in effectiveness in the production process
- Permanent functional monitoring of the system
- Any positioning of the curtain
- Integrated safety limit switches (PL d)
- No manual adjustment at the motor head necessary.
- No access to the drive necessary.
Technical features and benefits
Programování koncových poloh lze provádět prostřednictvím řízení, protože údaje o absolutní poloze lze odesílat prostřednictvím rozhraní RS485 integrovaného v pohonu.
The absolute value encoder is designed as a multiturn with a travel range of up to 40 revolutions and is also active in the event of danger, making it possible to stop in an exact intermediate position or move to the end positions after voltage recovery without reference travel. In addition, the function of the closing speed controller integrated in the drive can be monitored, as the speed of the winding shaft can be determined for the first time. Depending on the control unit, a speed that is calibrated during the initial commissioning can be evaluated during the monthly and/or annual inspection/maintenance or a defect/wear of the closing speed controller can be detected and reported at an early stage.
The state-of-the-art tubular drive with integrated locking device (working current brake) and the closing speed controller (centrifugal brake) is upgraded with an electronic position detection device in the form of an absolute value encoder. The drive race coupled to the winding shaft is connected to a spindle that meshes with two gear wheels. The gear wheels carry a positively connected magnet in the core. The angle of rotation of the magnets is determined by two underlying Hall sensors. The difference in the number of teeth results in unique positions up to a maximum possible travel of 40 revolutions until the gear wheels overlap. The electronics process the rotation angles into absolute position data and transmit this to the outside world via the RS485 interface using a dedicated protocol. The manufacturer of smoke and fire protection closures or smoke barriers is free to implement this protocol in his own control system.
Highlights and benefits
Greater safety, less effort
Becker tubular actuators with absolute encoders of the type AE FKB (8…28) 10A, in combination with the XCF-400e motor controller, make modern fire protection solutions smarter than ever before. Thanks to precise position detection, end positions and intermediate positions can be set very conveniently via the controller or using PC software. Best of all: manual adjustments on the motor head are no longer necessary.
The system also impresses when it comes to maintenance: configurable maintenance intervals, exportable maintenance logs, a USB-C interface and freely configurable inputs and outputs. Perfect for smoke curtains and textile fire barriers – a well-thought-out solution that takes innovation, safety and ease of maintenance to a whole new level.
Tubular actuators with absolute encoders for smoke and fire protection applications
The latest generation of tubular actuators with absolute encoders for smoke and fire protection applications combines innovation with tried-and-tested technology to deliver a new level of safety; it is ready to meet the structural and regulatory requirements of tomorrow and offers further benefits, which are illustrated in the video.
