      Fire protection curtains

      Fire protection curtains are seal openings in walls and ceilings in case of fire. The constructional set-up (rolling- or folding technology) and the use of different fabrics offer a wide application spectrum as well as different protection targets or classifications and time classes. Casings and side guides of those flexible applicable systems are integrated almost invisibly in the building and provide much scope for design of sophisticated architecture for opened designs.

    • Conveyor system closures

      Conveyor system closures

      Manifold production - and logisitc processes require different construction types of conveying systems. If the haulage drifts are passing through fire-retarding resp. fire-resisting walls or ceilings, the necessary openings must be provided with fire protection closures to avoid the expansion of the fire by conveyor technique or by conveyed material. In case of fire the conveyor system closures have to seal those openings immediately and automatically. Thereby a classified fire resistance as well as the smoothly clearing of the closing area must be respected in case of release.

    • Smoke curtains

      Smoke curtains

      A smoke curtain is part of unit keeping areas free from smoke and may include building parts like natural smoke and heat venting systems and automatic smoke and heat venting systems. Smoke curtains restrict the movement of fire gases inside a building in case of fire.

    • Smoke protection closures

      Smoke protection closures

      In closed condition smoke protection closures restrict the passage of smoke in the phase of fire formation so as to enable the rescue of people, animals or materials assets in case of a fire in the room positioned behind it without the need of breathing protection.

    • Tube sealings

      Tube sealings

      The solution to problems with fire protection dampers for ventilation and air conditioning systems in conveying processes. Stöbich offers fire protection for pneumatic conveying lines where the closing elements are not exposed to the flow. Thus, damage or contamination of the closure element is avoided by abrasive conveyed goods.

    • Controls

      Controls

      Control systems are necessary for all automatic fire protection systems! They are safety-relevant, because without their function or in the event of a malfunction, the entire investment of a fire protection partition would be useless. Controllers coordinate both fire detection and the interaction with other controls, like superordinate building control or the retraction of the closing area at conveyor closing area.

      Médiathèque Charles Nègre | Grasse, France

      The Médiathèque Charles Nègre in Grasse, France, is an impressive example of contemporary architecture that reflects the cultural and historical importance of the region. The information center with space for education, culture and encounters was opened in 2011 and designed by the renowned French architecture firm Marc Barani. The building combines modern aesthetics with the traditional architecture of Provence, creating a harmonious link between old and new, for example by combining modern materials such as glass and steel with local natural stone. The generous window fronts create an atmosphere flooded with light. Ecological sustainability is achieved through natural ventilation and the resulting reduction in energy consumption; green spaces are also integrated on various levels. Our <a href="/us/solutions/fire-protection-curtains/stoebich-fire-smoke-curtain-hc"><b>➥ horizontal Fire and smoke curtain hc</b></a> fire protection curtains fit perfectly into this marvel of contemporary architecture. They securely close the ceiling openings in the event of a fire, but otherwise remain invisible and let in plenty of light and air. Copyright attribution: © Ivry Serres

The bridging time of the Powerpack depends on the connected load

Powerpack

Example - Table for common unit combinations

Device configurationLoad current at 24 VBridging time
RZ8 + 1x Holding magnet0,115 Aapprox. 9 minutes 48 seconds
RZ8 + AM-S0,350 Aapprox. 3 minutes 28 seconds
RZ8 + 2x AM-S0,600 Aapprox. 2 minutes 5 seconds
RZ8 + AM-U0,400 Aapprox. 3 minutes 3 seconds
RZ8 + 2 x AM-U0,750 Aapprox. 1 minutes 42 seconds


The Powerpack keeps the output voltage of the power supply constant at 22 VDC over the bridging period. When the stored energy is used up, the PP3 switches off the output voltage to 0 VDC.

CAUTION: A short circuit of the charged Powerpack can damage the electronics. Please check the Powerpack after a short circuit and replace it if necessary. The defective Powerpack can be repaired in many cases. Please send it to Protronic, stating a QS number.

Note:
When using the PP3 in a hold-open system type RZ8 with the aBZ Z-6.500-2436 aBG RZ8 RZ24-FA, it is no longer necessary to change the loop resistance from 4k7 to 5k9.

Notice:
The Powerpack type 3 (PP3) replaces the Powerpack type 2 (PP2). The PP3 is downward compatible and can therefore be used as a replacement for a PP2.
