What does a verification system do if smoke is detected?

A verification system is designed to reduce the number of false alarms triggered by smoke detectors. When smoke is detected, instead of immediately activating the alarm and alerting the fire department, the system waits a predetermined interval before rechecking the detector. This approach allows for confirmation that the smoke is not a transient condition, such as cooking smoke or dust particles, which could lead to unnecessary alarm activation.

The preset interval may involve the detector checking for additional particles or changes in the environment to ascertain that the detected smoke is indeed indicative of a real fire hazard. By employing this verification process, reliable responses to genuine emergencies can be ensured while minimizing the disruption caused by false alarms. This function is particularly important in reducing the load on emergency response systems and maintaining trust in fire safety measures.
