Commissioning is simple.
After observing the spatial requirements for a reliable function (eg minimum distances from walls, corners and ceilings) described the ceiling bracket is screwed and screwed the detector clockwise.
First, I did not realize what the abknipsbaren plastic pins are needed in the ceiling mount.
If I have understood correctly, the instructions serve them as protection against tampering and theft similar to a good bike speedometer.
Only in the complete state, ie screwed into the ceiling mount, contact is made that puts the detector in the operating state.
This is all the 53 seconds indicated by a flashing red LED
By pressing the test button you can then check whether the smoke is actually working.
Please keep the detector something from the body and especially the ears off that 85db are very loud.
In the manual is the way explicitly discouraged by a functional test with an open flame, because the device might be damaged thereby.
We always eat in recent years, the 0815 detector from the hardware store, the batteries seemingly insatiable and, of course, always yelling exactly middle of the night after new batteries.
Since this detector a lithium battery has been installed which is designed for 10 years, this issue (hopefully) has done over the coming years.
A replacement of the battery is not the way, provided that the smoke detector must then inevitably wander in the waste bin. But I do not see this as a disadvantage, because with us still not a "normal" detector has ever achieved this biblical age.
Most break earlier contacts with the battery switch off or there is any malfunction that make the detector useless.
I am hopeful that this will not happen with this copy.
Because no additional costs arise also through the battery replacement is not necessary, the higher cost price armortisiert after a few years.
So I can recommend the DS32 smoke detector Avantek and do not mind spending the full 5 stars.
I hope this review could assist you in your purchase decision ....
