    6 Operations and Functions 6-1. Alarm activation Operations and Functions 6-1. Alarm activation Oxygen concentration alarm: Activated when the detected oxygen concentration reaches or exceeds the alarm setpoint value. <<Auto-Reset Operation>> NOTE The alarm setpoint is factory-set. Although the alarm delay time (standard: 2 seconds) works in the detector to prevent a false activation, it can be cancelled if not needed.
