Control of Fire Dampers and Smoke Extraction Dampers
AS-Interface – Building Automation
The advantages of AS-Interface – such as simple, cost-saving installation and high degree of flexibility – have now become familiar in building automation as well. Numerous companies are relying on the ASi installation system for applications such as controlling fire and smoke damper systems, shutter drives or heating and cooling ceilings using analog output modules. Damper actuators with flow regulators can also be connected to the controller through the MP-Bus Gateway. It is also possible to process EnOcean signals from wireless buttons and sensors through ASi. Customer proximity is our hallmark, which means we stand by you in word and deed and are open to custom-tailored solutions. Just contact us.

Genormter Industriestandard
ASi ist ein weltweit genormtes industrielles Verdrahtungssystem (EN 50295, IEC 62026-2) mit über 32 Mio. verbauter aktiver Module und über 1.800 zertifizierten Produkten. Über die volle Kompatibilität aller Produkte untereinander wacht die Nutzerorganisation der 350 Mitgliedsfirmen.
Verdrahtung
AS-Interface ist ein genormtes, industrielles Verdrahtungssystem für die Automatisierung, das für den Anschluss einfacher E/A Module (z. B. digitale, analoge und sichere E/As) gemäß EN 50295 und IEC 62026-2 entwickelt wurde. Alle Teilnehmer lassen sich mit Hilfe eines einzigen zweiadrigen Rund- oder Profilkabels ( ASi Kabel , 2 x 1,5 mm2, 16 AWG) bei freier Wahl der Topologie mit dem Master verbinden. Das ist der wesentliche Vorteil von ASi gegenüber der konventionellen, parallelen Verdrahtung, bei der jedes einzelne Signal direkt mit der Steuerung verbunden werden muss. Über dasselbe ASi Kabel werden Daten und Energie übertragen.
Low costs
AS-Interface drastically reduces wiring and installation cost and makes expansion or retrofitting very simple.
High availability and safety in accordance with SIL – problem free
AS-Interface also enables safety-relevant systems (EN ISO 13849) to be equipped with interference protection. High-availability or redundant systems (even with circuit integrity) and systems with special safety requirements, such as SIL1, SIL2 or SIL3, all fall under the application spectrum of ASi. The cabling route and communication with all participants are constantly monitored, even in the standard version. This ensures that all dampers can be still controlled in the event of a fire.
Installation – very simple
- AS-Interface provides a clever connection technology over a profiled cable. Lay the cable, screw on tightly, ready. Contact pins always penetrate vertically into the profile cable to guarantee optimal contacting
- Optimal contacting provided by:
- Vertical contacting
- 4 or 6 pins per cable and 2 or 3 pins per conductor
Gateways for linking to any Building Management System

It is possible to use a specific cable for various applications. For instance, the profile cable with polarity reversal protection is suitable for fire dampers. It is halogen-free and available in 1.5 mm2 or 2.5 mm2. However, it may also be possible to use a pre-laid round cable, such as NYM 2 × 1.5 mm2 or NYM 2 × 2.5 mm2. In terms of smoke extraction, cables with circuit integrity (e.g. E90) are often necessary.
Anschluss
Der Anschluss an die Brandschutz- oder Entrauchungsklappen ist meist steckfertig über die AMP-Stecker der Antriebe möglich. Alternativ ist der Anschluss über Push-in Federzugklemmen bei Antrieben mit Litzenanschluss möglich.
Einfach – bei maximaler Flexibilität.
The ASi masters can transfer all data to a higher level control or process them locally depending on the application and their requirements. In terms of local processing, they offer maximum flexibility, and they are freely programmable or provided complete with a pre-installed program for many application scenarios: connect - ready. Of course, all state information and diagnostic messages from the building control system are always available. An integrated web server enables remote diagnostics even from computers without diagnostics software.
The comprehensive package is rounded off by comfortable tools for commissioning, diagnostics and test runs.
