Electrically controlled hold-open systems for fire and smoke control barriers function and operation


If fire/smokeproof closures intended to be kept closed a fire event are to be held open for easing daily business, they must be equipped with electrically controlled hold-open systems. These shut protective doors immediately + safely in case of fire, preventing the spread of flames and smoke. They protect human lives and expensive goods as well as the buildings themselves – making them an important part of safety concepts.

An electrically controlled hold-open system consists at least of an arrest, release, power supply and fire detector.
