Smoke & Heat Ventilation Systems

E 260

The RWA emergency power supply unit E260 N is the central control unit to which all components are connected. It controls these components and provides them with power. Activation in the event of a fire is via automatic smoke detector, manual RWA switch or external alarms.

Activation causes the RWA openings to open or close, depending on the configuration of the RWA emergency power supply unit. By means of vent switches drives at the windows and smoke extraction openings can be controlled for normal ventilation operation. The RWA function is a higher level function than the ventilation function.
