How long does it take for a Full Alarm to occur after a Pre Alarm?

The time it takes for a Full Alarm to occur after a Pre Alarm is 12 seconds. This interval is critical for ensuring that users of the Scott Air-Pak X3 SCBA have sufficient warning if there is an issue with the air supply or if they become incapacitated. The Pre Alarm acts as an alert for the user, prompting them to check their equipment or take action if necessary. The transition to a Full Alarm signifies a more urgent situation that demands immediate attention, allowing team members to respond quickly. Understanding this timing is essential for ensuring safety protocols are followed and that personnel are prepared for potential emergencies.
