All items from the HX system are compatible with each other and can be freely supplemented and expanded. The HX Moonlight wireless receiver features a night light function with dusk automation and a stylish acrylic front. The HX system offers an easy-to-use self-learning function for adding additional components. To extend the range, one or more range extenders can be connected. Additional transmitters, such as the HX wireless motion detector or the HX wireless door sensor, can also be integrated into the system. To avoid interference with other wireless transmitters, the HX system offers 256 frequencies that the device learns automatically.

The HX Moonlight wireless doorbell set includes a waterproof transmitter (IP55) with a nameplate, which is protected against water jets and already comes with a battery. The volume of the chime can be adjusted to 4 different levels, with the highest level reaching 95 dB (A). The receiver can play 8 different melodies. An optical call signal can also be activated alongside the melody, which is displayed as an orange light.

The night light function allows the receiver to shine continuously and responds to the dusk automation. It is possible to turn off either the optical signal or the sound. With the on/off switch, the doorbell can be easily and quickly silenced. When using additional transmitters, each transmitter can be assigned a different melody.
