Purposefully Delayed Fire Alarms

Often an owner has a strong desire not to activate fire alarm notification in their facility so as to not needlessly disturb facility operations and occupants.  This presentation details the Code-approved options for delaying the activation of fire alarm notification.  These options include automatic notification, presignal notification, positive alarm sequence, and detector cross-zoning.  This presentation will discuss the code requirements for each option and the critical considerations for an owner and designer, as well as the authority having jurisdiction who must approve these unique options.

This presentation will feature the following learning objectives:

  • Why would an owner wish to delay or prevent fire alarm notification activation?
  • What are the three Code-allowed options for delaying the activation of notification?
  • What are the specific Code requirements and critical considerations when considering delaying notification activation?
  • When should fire alarm activation never be delayed?
