Early and reliable fire detection in ceiling voids, trenches and raised floors

High flexibility ensures asset protection and business continuity

Ceiling voids (including suspended ceilings) and raised floors are essential parts of a building for the running of building services, spaces for electrical and data cabling, control equipment and cabinets. These areas are deemed as concealed spaces in a built environment because they are often isolated, unoccupied or obstructed from the sight of view. Concealed spaces can be found not only in almost all large built industrial environments but also in shopping malls, transportation hubs, exhibition centres and tall residential and commercial buildings. When these spaces are also used as air plenum to form a part of building HVAC air circulation, air velocity inside these concealed spaces can be extremely high, particularly for cleanrooms and data centres.

If a fire, originating from a concealed space, is detected too late or encountered with inadequate response measures, the resulting damage can be substantial. In addition to the damage as such, a fire is likely to jeopardise business continuity for mission critical infrastructure like IT or telecom operation

Causes of fires in ceiling voids and raised floors

  • Mainly electrical related incidents due to energised cabling in high density

Challenges to early detection in concealed spaces

  • Dust build-up over time, even oily dust in industrial premises
  • Very high or irregular airflow patterns when used as air plenum due to fast or changing air circulation
  • Subject to changes of the ambient conditions such as temperature, humidity or other
  • Difficulties to pinpoint the source of an incipient fire

Key benefits of early warning fire detection system in ceiling voids and raised floors

  • Reliable fire detection at an early stage with multiple alert levels
  • Fire alarms are reacted upon in a professional manner before they become a major fire incident
  • The loss prevention is at a maximum and the risk for business interruption at a minimum
  • Low maintenance cost
