Possible conveyor systems for the use of a conveyor system closure include roller, chain and belt conveyor systems and electric overhead conveyors. Only specially tested conveyor system closures may be used. In addition, the closures must have an approval from the German Institute for Building Technology (DIBt) or a European Technical Assessment (ETA).
In order to take the different types of systems into account, the fire protection closures are individually adapted to the respective situation and the specific framework conditions. In addition to the approved conveyor system closure, it is equally important to install a control system that is adapted to the requirements. For this purpose, Hodapp GmbH & Co. KG has its own control system with which even complex requirements can be implemented.
The approved battery-buffered “HPS-Advanced” type holding system is available to keep the gates open. This holding system can be expanded modularly to include an “HPS-Drive” release control to control the conveyor drives and an “HPS-Power” backup power supply to supply these drives, which are required to clear the closing area in the event of a fire.
In order to ensure that the control processes are also carried out under fire conditions, additional tested sensors such as fire protection light barriers are used. These light barriers are able to safely monitor the gate area even when there is a lot of smoke and create the conditions for reliable control of the local system components in order to then ensure reliable and safe closing of the lock.
