All items from the HX system are compatible with each other and can be freely supplemented and expanded. The HX Moonlight radio 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 radio motion detector or the HX radio door sensor can also be integrated into the system. To avoid interference with other radio 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 doorbell can be adjusted in 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, displayed as an orange light.

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