What is the purpose of a verification system in fire alarms?

The purpose of a verification system in fire alarms is to wait a preset interval before checking a smoke detector again. This approach helps to reduce false alarms triggered by temporary conditions such as cooking smoke or steam. By allowing some time to pass before re-evaluating the smoke detector’s readings, the system can determine if the smoke presence persists or was merely a fleeting occurrence. This helps to prevent unnecessary evacuations and responses to false alarms, which may lead to alarm fatigue among occupants and responders, thereby improving overall safety and efficiency in fire response systems.
