The key ring radio transmitter FS3 H2 serves as a handy remote control for Schalk radio controlled relays and dimmers.
It can be configured with 2 (factory default) or 4 buttons (additional keypad included). A DIP switch is used to individually set the transmitter address.
Additionally, the layer and button number can be set to be compatible with our other radio transmitters FS3HCor FS3 H8, if these are used in parallel.
The range in open air is at least 30 metres.

Scope of supply:
1 x hand-held transmitter
1 x keypad "2-button"
1 x keypad "4-button"
(keypads can be exchanged!)
