There's a very strange test/alarm sound that occurs every 34 minutes. I checked the smoke alarms and replaced the batteries so it's not coming from those.
It almost seems to be coming from the kitchen, maybe the fridge? But I cannot quite pinpoint it.
Please see the link below for a sample of the alarm sound.
