PRO:
- High-quality housing. Aluminum brushed. High wall thickness. However, surface mounted with ca. 1.5cm wall distance.
- Backlighting with dark sensor
- Large buttons, 2-fold stored (. You can press, where you want the keypress is reliably detected)
- Also suitable for old bell lines. For description see below. There must be a line from Klingeltrafor (AC voltage from 8-12 volts). Schaltleistiung 1A.
- Splash protected by rubber bellows at all screw points. Should rain endure. Has an IP44.
Cons:
-. Backlighting to light also of Poti works inside insufficient as dimmer. Here you have to either solder a further resistor, or use multiple layers of paper. This also leads to exactly the point deduction.
Wiring:
The bell has a total of three different types of wiring. This is independent of the number of buttons. My description therefore also applies to the 1-button or 3-button versions here on the net.
Type 1: arrive at the doorbell plus / minus supply lines of the bell transformer to. The two lines go from per bell. So lines 6 in this case.
Here the bell transformer is connected to the two inputs. The bell there are two exits, both for bell transformer switched on keypress. The backlighting will always work.
Article 2: Only Klingeltrafo plus goes into the ring, but here 3 times (backlighting, Bell 1, Bell 2) by means of small wire jumpers inside. The latter are not in, but must be made of a simple strand short itself. Klingeltrafo minus goes directly to the lines of the bell. The bells are connected to the positive outputs. So similar to type 1. Advantage: Switching this is possible if there arrive only 3 lines, but the other lines are available elsewhere in the house. As above, the backlight goes on.
Article 3: This was my case. Outside come only 3 lines of (old house). A Plus from bell transformer with 10V and two outlets to the bell. Per apartment a wire. Also for this case provides the bell a solution. Transformer plus and a bell wire are connected to the supply of the probe. The same bell circuit is also to an output bridged (small cable inside). The second bell normally connected to the remaining output. Disadvantage: It flows through the LED lighting still a very weak current in the bell. Due to the high internal resistance of the LED, this current is very low. If the button is pressed the doorbell, the full power and it rings flows, but the backlighting goes out (short-circuit of the LED). This principle only works with electromechanical ringing (the normal thing-Dongs or Schrillllllllll thingies). An electric Gong could already be interpreted as the low power ring signal. The coil of the electromechanical bell is slightly time-energized (no, that's not Schweinkram. That is so). The second gong can then also be an electronic. At his press the backlight does not go out.
Personally, I was happy that my very old wiring can still make such a beautiful bell with light possible. Therefore, full 5 stars for the function.
Tip: If Conrad can download the circuit diagrams.
I hope I could help you with your purchase decision!
