Fire Friday Series

What is important when selecting a fiber optic Linear Heat Detection (LHD) system? Is it wrong to equate measurement time with response time? How many channels are optimal for your configuration?

AP Sensing was launching a new series to find out more every Friday about fiber optic LHD including:

  • sensor cable approvals
  • spatial resolution
  • system configuration
  • alarm thresholds
  • system reliability factors
  • and more

Severe vehicle fire demonstrates critical need for AP Sensing linear heat detection
Fire Friday #1: Linear Heat Detection Response Time

The alarm parameters in AP Sensing's LHD system are freely configurable, but we offer sets of alarm parameters that have been tested by reputable institutes such as UL, FM and the VdS. This gives our customers the assurance to find an optimal balance between fast response time and false alarm resilience.
