Fire protection doors

Control technology

The control concept is consistently designed for decentralization according to the requirements of practice. This means that all control components (locking system, door clearance control with drive switchings) consist out of modules which are mounted directly on site, that is in direct vicinity to the conveying-system closure.

The separate control components are built as modules and consist out of the following structural components:

  • locking system
  • extension module (in case of several closures, coupled with locking system)
  • drive electronics (conveying-system closure drive, only with closure basic type B - manual reopening)
  • automatic door clearance control (AFM)

The concept is rounded off by various reasonably priced and high-performance emergency power supply systems.

Locking system:

The locking system is especially designed and approved for the implementation of conveying-system closures. It consists of the following modules:

  • 24 DC power supply 
  • battery charging unit and battery monitoring system (separate charge and trickle charge supply of the maintenance-free batteries)
  • release mechanism
  • fire recognition components, release button, closing area monitoring

Door clearance control:

The door clearance control ensures that in case of fire recognition the closing areas are cleared unter circuit and circuit-failure conditions. Prerequisite for an orderly function is that the closing areas are monitored (e. g. via a light barrier) and that an emergency power supply system for the drive motors of the conveyor is available. The door clearance consists out of the following modules:

  • door clearance control module (FSM), integrated into the casing of the locking system
  • automatic door clearance module (AFM), switching at the conveying-system motor.

Emergency power supply:

In case of activation the drive motors of the conveying-system are used to clear blocked closing areas. The clearance of the closing areas is also ensured in case of power failures. In case of circuit failures an automatic switching to emergency power supply takes place. Depending on the application, emergency power supplies are available in different versions and performance classes.

Standard signal exchange:

For the signal exchange with the conveying-system engineering the following floating contacts are available:

  • no release
  • conveying-system closure open
  • conveying-system closure close (only with end switch)
  • closing area blocked (only when light barriers are used)
  • no malfunction
  • network failure
