My main concern is not to identify a possible fire at night time. He who sleeps can not perceive odors. However, we are awakened by noises. Therefore, save lives the shrill tone of this smoke alarm in an emergency.
Where the smoke alarms are best installed, going from the manual. We hang the part on the ceiling of the hallway upstairs.
The smoke from Avantek comes in a cardboard box. It is battery powered. The battery is permanently installed and is for 10 years in an emergency to trigger the alarm. With a little skill and effort the interior can be visited. Welded wire sits there the battery. Theoretically, the battery is interchangeable with craftsmanship. However, that is of course not recommended. Should the battery falter, but which is notified in good time by a recurring little warning.
On the device itself, there is a test button. Who pushes him, must "live" hear the shrill sound once. 85 decibels, he says it is - and yes, most hold the ears ... In addition, a red LED light indicates that once flashes approximately every 30 seconds that the alarm is "sharp". Of course, it raises an important question: When unpacking this LED flashing every 30 seconds and was therefore already active. How long the device is already active? Since the production of? If the smoke detectors been 3 years in any stock? I have now only a term of 7 years? A protection for pulling out would have been desirable. Then a longer maturity would have been guaranteed.
Practical and standard is the hub on the back. This is attached to the ceiling using the supplied screws. Now The smoke detector can fix it with a rotary motion into the holder. Simply, quickly and safely.
The penetration of smoke is possible from all sides.
I hope we will never need to smoke detectors. The money is still invested well. It provides a little security. Because the processing is correct and the test alarm works, we are in good spirits. We are considering to create more smoke detectors. So far, we are satisfied.
