If you use a Series 9 gong as the first gong, the range to the second gong can be up to 400 metres. Series 9 radio gongs have a range amplifier that relays the signal to the next gong. This would be one of the Series 9 Honeywell Radio Gong (Radio) .
There is no information from the manufacturer on whether ringtones can be added to the device on the manufacturer's website. However, we believe that this is not possible.
Yes, that is possible. I have linked 3 units with each other. You can even assign different ring tones.
By the way: The button cells in the bell buttons quickly have trouble in winter temperatures and have to be changed often.
That's exactly how it is. The thing is a completely normal radio door chime. You press the button and the receiver then rings in the desired tone. I find it very practical that you can not only set the ring tones, but also a flashing light on the receiver.
The chime has no intercom function.
