What is the maximum time allowed for the alarm condition to be displayed and recorded at the supervising station after activation of an initiating device?

The correct answer indicates that the maximum time allowed for an alarm condition to be displayed and recorded at the supervising station after activation of an initiating device is 90 seconds. This time frame is specified in various national and local codes related to fire alarm systems, particularly in the context of ensuring a prompt response to emergencies.

The reason this duration is significant is that it aligns with industry standards to facilitate timely intervention during potential fire incidents. If the alarm condition is displayed and recorded within this timeframe, it ensures that the supervising station can react swiftly to the alarm, potentially reducing property damage and increasing the chances of safely evacuating occupants.

The other options represent durations longer or shorter than the established maximum, which do not meet the standard protocols and could hinder the effectiveness of emergency response by delaying notifications to the appropriate authorities. Thus, adhering to the correct time limit is essential for maintaining optimal response efficiency in fire protection systems.
