In months no false alarms

The idea was to install four smoke detectors in the house. It was important that no possible cause false alarms. In the various test reports, this model was as though for a long time in the trade, as well as reliable. After ordering all four smoke detectors were delivered in a few days in one package. For installation I have waived the enclosed dowels and screws. Instead, I bought at the hardware store around the corner low magnetic disks, which were provided by the manufacturer with adhesive film. They were provided specifically for smoke detectors, albeit for round.

Thus, the assembly went jiffy. A plate glued to ceiling (Rauhfasertapete), a plate on the bottom panel of the smoke detector, does the rest of the magnetism. Perfect.

For about five months hang all four smoke detectors, there has been no false alarm. That they work, but you can easily test by pressing the test button. The sound is loud enough that you would awake. In the test button is a small red lamp that flashes approximately every 40 seconds. The flash is very weak, barely visible. I do not mind in the bedroom asleep.

The device itself I felt at the beginning as relatively large. Again habituation has used quickly. Although smoke alarms are never really good, but the here is really okay. Would I buy it again.

Supplement 06.04.2014:
The first set of batteries held 23 months. Then the first of four smoke detectors has been remembered with a faint beeping. Since the installation, there was not a single false alarm. This part of the mission was fulfilled. The real thing is hopefully still pending.
