The device is working properly (I tested it with a cigarette lighter; distance from the flame about 35-40 cm)
A 9V battery is already at.
For the bracket, two screws and plugs are included. But habs made simpler and ordered this part: Elro RMAG2 magnetic mounting for smoke alarms / smoke detectors / magnetic mount
Just awesome! Within 3 min. I had installed the heat detector.
The installation is very simple. In the living room and bedroom I have smoke detectors installed (by the way also by Bavaria Bavaria BARM210 VDS smoke detector fire detector with 10 year lithium battery DIN EN 14604, pure white, 4-pack,
but in the kitchen which is problematic because it may lead to false alarms through the haze when cooking. Since the heat detector is the perfect device, if times on the stove that burns. I can only recommend the device. Little money for a lot of security!
ADDENDUM:
Oh, by the way've ordered another:
For the bathroom!
Why?
A smoke detector makes little sense there because of the steam development. And because I have there are a washing machine, I also wanted to protect this space as far it goes.
