The transmitter (The bell push housing) does not have the suspension shown here. If necessary, but can an enclosed metal tongue (clip) are mounted with drilling.
The transmitter has pierced on the back of four small rubber grommets as an introduction for the veins, they are and I can introduce effortless two 0.5 mm2 wires our bell circuit.
The four terminal screws in the transmitter housing does not allow for the use of wire end ferrules, for they are too short.
However bell wire or directly 0.5mm2 conductors can be connected without any problems.
The respective cover of the transmitter housing is supplied with two Allen screws (key is included) fastened.
Protection should be IP54.
Application range -15 to 50 degrees Celsius
Important.
This transmitter can be combined with an existing doorbell system.
BUT, you need basically two batteries 1.5 V LR03 / AAA Alkaline, life in the transmitter according to the manufacturer 5 years
or
6 to 12 volts DC.
Operate the transmitter you can use:
The button located on it
or
with an existing floating contact your bell system
or
drives with an existing on the door contact of your existing doorbell system with the household 8 to 12 volts AC.
Provide the sender with this AC voltage 8 to 12 volts, you can not.
This also ruled out that you can use the quite elegant transmitter housing as a trigger for your existing doorbell system.
This latter limitation I did not expect, bad luck.
Transmitter therefore only three stars.
~~~~~~~~~~~~~~~~~~~~
The recipient can
4 Batteries 1.5 Volt LR14 / C alkaline (baby cell)
Life according to the manufacturer 5 years
or
via supplied adapter with 4 batteries 1.5V LR6 / AA alkaline life according to the manufacturer 1 to 2 years
operate.
A switch for the battery power of the receiver is missing here, the manufacturer recommends to remove the batteries when not in use.
In the case of AA batteries quite a FingerNagelBrechFummelei, caused by the adapter.
Background, I need the device usually only from time to time in the garden when Amazon packages come :-))).
The concept of LED display and programming buttons does have room for improvement but it works. However, the mute circuit and associated LED display is a joke.
Temperature range: 5 to 40 degrees Celsius in dry rooms and no direct sunlight.
Otherwise, the system, both the sender and recipients, elegant and functional.
But about taste can be so worthy of debate.
Which I must confess that I do not have channels set / learned only one of 17 ringer melodies.
Tone and volume were fine for me.
In the end position of the volume control (very loud) overrides the device easy and the sound is tinny.
Especially the ringer melody followed Hundgebell us and our neighbors was fun, too.
If you want to hang up the receiver, which is corresponding bore in the housing due back by the shape, you have to stick out of the wall, the wall mounting screw approximately 1cm.
In standing position sufficiently stable.
Receiver three star.

I recommend before purchasing from the Internet to download the installation and operating instructions.
I have not copied here, because usually Amazon weglöscht any Internet addresses address.
Since I already had to dispose of scrap function in similar price range for this device from me quite a buy recommendation.
If there are any long-term problems that will grudge here.
