Service Description : Control units are the brain and th... Control units are the brain and the power supply of the smoke and heat extraction system (RWA) in your building. They control all smoke and heat extraction system components for safe smoke and heat extraction in case of fire. The emergency power supply units are the control unit for all fresh air and exhaust air openings equipped with smoke and heat extraction drives. They record the notification of the SHEV buttons and the automatic triggers, e.g. the smoke detectors, control the smoke and heat dissipation, and monitor the components to detect interferences. A smoke vent is part of preventive fire protection and ensures that smoke is extracted in the event of a fire. The objective is a stable layer of air with little smoke near the floor so that escape and rescue routes can be used safely. An open smoke extraction also carries away heat from the fire. This means that the load-bearing behaviour of load-bearing or separating construction components is extended considerably. For this reason, the terms smoke extraction and smoke/heat extraction (RWA) are often used synonymously. Smoke extraction is designated as natural smoke extraction (NRA) if it works via natural thermal lift, so without additional ventilation drives (such as ventilators). Natural smoke and heat extraction units (NRWG) include, for example, windows, skylights, ventilation blinds which automatically open in the event of a fire and help draw smoke and hot fumes out of a building.
