Why is Fire Alarm Strobe Synchronization so Important?

According to the Epilepsy Foundation’s website, 1 in 26 people in the United States will develop epilepsy at some point in their lifetime. The purpose of synchronization is to ensure that the fire alarm system visible signals do not cause a photosensitive epileptic to initiate a seizure.

NFPA 72 – 1996 edition and later editions stipulate that strobe synchronization shall comply with Americans with Disabilities Act. Consequently, the NFPA code requires that the strobes are to be synchronized when more than one is visible from any field of view. The manner in which fire alarm systems accomplish this is through strobe synchronization.

What is strobe synchronization? It is a protocol that is used on a notification appliance circuit (NAC) to allow the strobes to flash in “sync”. Today, most Fire Alarm Control Panels and NAC Power Supplies have Built-in Strobe Synchronization protocols.
