Tailored smoke ventilation solutions:
+ Stand-alone system or integrated with existing fire alarm interfaces
+ Multi-zone and internal options
+ Optical smoke alarms and heat alarms
+ Data transmission across BUS technology
+ Integration with natural ventilation via automatic vent opening

Without an NSHEV system
  Toxic gasses, smoke and heat accumulate in the building
  Lives are endangered, rescue work is impaired and property is damaged

With an NSHEV system
  Vents and air inlets remove smoke, gas and heat
  Smoke is diverted to produce a stable smoke layer boundary

NSHEV Operation
NSHEVs clear escape routes of smoke, and/ or provide smoke-free space for fire-fighting. They can vent directly via external walls / roofs using windows, louvres and rooflights, or through internal smoke shafts via smoke dampers. NSHEVs can be triggered automatically via smoke detection or fire alarm interfaces, or manually using call point units, opening fully within 60 seconds. NSHEV’s can be reset and closed automatically or manually through the control system.
