Important for life

The smoke detector arrived well packaged and undamaged with me.
Content: In the parcels were 4 smoke detectors with batteries, manual and four spare block batteries.
The smoke detectors were individually wrapped.
They are white with an indicator light and a test button. The alarm is really very loud 85 db. This is of course very important and vital.
We have a ground floor mounted at the ceiling and closed all the doors. Then pressed and amazed that the test button it is higher so good to hear a stick.
The others were upstairs and assembled in the nursery.

The installation is very simple and the appropriate mounting hardware is included. It is turned off, the lower part and these screwed to the ceiling using the supplied mounting hardware. Then the Smoke Alarm can be done easily on. I sleep better repays since we installed smoke detectors in the house. This can save lives. Of course, everyone hopes that it never used one is concerned, but you can not be sure, and I find this smoke detector really great and reassuring.

It should be checked every week if the batteries are still working. For this, the test button is pressed for a few seconds and the alarm goes off. As long as the alarm tone will sound when testing the batteries need not be changed.
If the battery is low, the smoke detector is a quiet beep. We tested with an older weaker battery and it came at frequent intervals a faint signal.
Spare Block batteries were supplied in identical set so that in future nothing can go wrong.
The smoke detectors are suitable by their plain white design with us to our white ceiling and difficult to spot.

The price at the moment of nearly 25 euros for a four-set I find inexpensive. And are considering the total of 8 batteries for this price you can not complain here.
I highly recommend this VisorTech smoke detectors very happy to and would buy me anytime itself.

Positives:
- Good value for money
- Easy assembly
- Very loud warning sound
- Beep when battery is low
- Test button
- Simple unobtrusive design
