What is the standard for positive alarm sequences in fire safety systems?

The standard for positive alarm sequences in fire safety systems is indeed 90 seconds, which allows adequate time for verification and response without causing unnecessary disruptions. This standard is critical in fire alarm systems because it helps distinguish between actual fire situations and false alarms, which can occur frequently if the delay is too short.

Having a 90-second interval allows the monitoring personnel to verify the alarm and assess the situation properly before a full response is initiated, thus preventing potential panic and improving overall safety. It provides enough time for the system to determine if the alarm is genuine based on the signals received and ensures that appropriate measures can be taken, fostering an environment where responses to fire alarms are both timely and measured.

In terms of fire safety management best practices, this standard reflects a careful balance between alertness to potential dangers and reducing the likelihood of false alarm fatigue among occupants and emergency responders.
