Light bands

Bauhaus Zagreb 2

Alux light bands are larger skylights that easily provide intense natural lighting in buildings with large open rooms. The skylight bands are linear skylight elements, constructed in optional lengths. They can be installed on any roof structure. They provide particularly intense lighting in galleries, studios, workshops, warehouses and in industrial, public and commercial buildings.

3-in-1

Skylights = Natural Lighting + Ventilation + Natural Smoke and Heat Exhaust

Thus skylights can be used under normal conditions for lighting and ventilating rooms, whereas in the case of fire they serve as natural smoke and heat exhaust from rooms that are on fire.

Choice of Devices for Natural Smoke and Heat Exhaust

  • pneumatic CO2 opening mechanisms
  • electrical opening mechanisms (activated through the fire central or a fire alarm)

CO2 Opening Mechanisms

Are pneumatic opening mechanisms. The basic principle behind it is that in the case of fire the temperature vial is activated at a specific temperature, which in turn activates the bomb, the propellant gas then fills up the pneumatic cylinder and the piston rod opens the skylight.
Depending on the requirements of a concrete project, the CO2 bomb can be activated with the temperature vial or with a signal from the fire central or from fire alarms such as manual alarms, smoke detectors and the like.

  • they are used for various opening angles and are suitable for higher skylight loads
  • an advantage of CO2 opening mechanisms is that after they are opened the skylights can be closed more easily (closing them from the ground is possible). CO2 bombs are suitable only for single-use, which is why they must be replaced after they have been activated.
  • CO2 opening mechanisms can be combined with electric motor opening for ventilation needs

Electrical Devices for Opening Mechanisms for Natural Smoke and Heat Exhaust

24V electric motors are used for natural smoke and heat exhaust, which receive the signal to open from the fire central.
Important:

  • electrical opening mechanisms require an additional source of voltage, which would be used in the event of a power failure
  • closing them from the ground is possible – in the event of a false alarm, no elements need be replaced
  • dual use of electrical opening mechanisms:
    • for smoke and heat exhaust
    • for ventilation

Activating Devices for Natural Smoke and Heat Exhaust

Depending on the requirements of the project, the devices for natural smoke and heat exhaust are usually activated at temperatures from 68 to 141°C:

  • with a temperature vial that is activated at a specific temperature,
  • through the fire central or a fire alarm.
