Particularly annoying is when the false alarm goes off in the middle of the night and the whole family electrified jumps out of bed. The networking worked well in the case - all devices in the house shouted to the bet.
But without reason.
After we had just fallen asleep again, has the same repeated once more.
We thought it was a particular device in one of the rooms, which triggered the alarm.
So we sorted out these smoke detectors.
Two weeks later: false alarm of the remaining devices in the afternoon, again without any occasion,
For most devices, the battery is removed - otherwise the things not listen to because there is no button to turn off stupidly.
Then: false alarm last remaining unit within the next hour.
Crap things, all I can say!
Even if the batteries are running low, is, no, there must be in any case a complete alarm !!!
In addition, the battery warning tone is different, namely a weak beeping, about once every minute.
Manufacturer, here you need to urgently make improvements!
