When the alarms are set for delay and an alarm condition exists, the display will alternate between the O2 reading and the time in minutes and seconds before the alarm will trigger. The alarm indicator on the front panel will blink on and off. The delay time will continue to count down until it reaches zero then the alarm relay will close. At this point the display will stop blinking and the O2 concentration will display continuously. If a second alarm is reached after the delay time has elapsed, it will trigger immediately without any delay. If the O2 level drops to below the alarm condition during the delay, the delay timer will reset to the full delay.
If the alarm delay is set to 0 and an alarm condition exists, the alarm indicator will blink and the alarm relay will close immediately. When the O2 level drops out of the alarm condition, the alarm relay will drop out accordingly.
