C&E FS20 Wireless transmitter unit FS20 S4UB 4-channel Max. range (open field) 50 m 57125 Fiche De Données

When installing the device please make absolutely sure that you carry out the
steps in the following order.

1. The ‘FS20 S4UB’ flush-mounted battery transmitter is normally installed in a deep

installation box. Before installing the device, you can mount an installation button, which
you can then use to operate the ‘FS20 S4UB’.

When choosing an installation location, make sure that there are no voltage-
carrying conductors

 

in the immediate vicinity of the transmitter as these may

restrict the transmission range.

No sharp edges, sharp points or similar should be located at the installation
location. These could damage the insulating film and cause short circuits,
which could then destroy the flush-mounted battery transmitter.

Also make sure that you do not place the transmitter in a metal casing that is
closed on all sides (no radio signals possible).

If voltage-carrying conductors are laid in the designated installation box (or a socket or a
switch needs to be removed, in the case of multiple covers, for instance), then you should
take the following necessary measures:

Make sure that nobody accidentally switches on the electrical circuit (safety
warning on the in-house distributor, mechanical block, etc.).

Then use a suitable measuring device to check whether the affected electric
circuit is fully voltage-free.

Only then should you continue (by removing the socket/switch covers, for
example).

2. Wire the flush-mounted battery transmitter with the external buttons as shown in figure 1

in section 5. a). Make sure that all the connections are securely fixed to the terminals of the
buttons.

All the unused wire ends of the ‘FS20 S4UB’ must be insulated using the
supplied covers and should not be connected anywhere else. Never shorten
the cables. If you require longer cables, use suitable terminal strips/junction
box terminals.
