Audio alarm (optional factory setting)

In case an upper or lower alarm is triggered, 3 audible alarm signals are emitted immediately. Thereafter:

• Every minute 1 alarm signal for maximally 168 hours (7 days).
• After 168 hours (7 days) the buzzer will stop.
• If an alarm event is confirmed (READ is pressed) while the limits are still exceeded the buzzer pauses for approx. 1 hour and then restarts beeping every 3 minutes.
• Confirmation within the alarm limits will stop the buzzer.
