Battery Radio Bell with Kinetic Radio Push Button, Light & Sound

Never miss a visitor again: thanks to ringtone volume up to 75 dB and optical light signal. You'll hear visitors at your door even when you're vacuuming in the living room or sawing wood in the garden!

Simple and flexible set-up: Mount the button on the entrance door, back door, etc. Simply place the battery-operated bell where you can hear and see it - up to 150 meters away. Done!

One wireless pushbutton for all your receivers: You can couple it to as many KFS-150 receivers as you like. If you expand the system to include receivers in bedrooms, living rooms and offices, one button will trigger all your doorbells at the same time, if desired.
