The best way for claims professionals and investigators to understand alarm systems is to know the fundamentals.

  • Why was there a delay in the fire alarm system’s activation?
  • Why didn’t the alarm activate?
  • Why didn’t the central station receive an alarm signal?
  • What alarm system evidence do I need to preserve after a loss?
  • The alarm system transmitted signals to the central station, but they did not dispatch the authorities.
  • What does a failure to communicate and/or test fail signal mean? Does it matter if automated test signals are not supervised?
  • What is a central station database printout?
  • What is an NFPA inspection and testing form?
  • How long does a central station have to dispatch the fire department after they receive a signal?
