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

To enable several FS20 components (including the ‘FS20 S4UB’ flush-mounted battery
transmitter) to be operated in the same area, extensive coding is used to protect the radio
transmission.

The code consists of a ‘house code’ and an ‘address’. The house code serves to differentiate
between multiple FS20 systems operating simultaneously. This means that your neighbour
can use the same wireless control system and the two systems will not interfere with each other
(provided that the house code has been programmed differently).

The house code consists of 8 base-four digits (1, 2, 3, 4) meaning that in total 4

8

 (= 65536)

different house codes are possible. This makes it extremely unlikely that your neighbour will
use the same house code (assuming that you do not use ‘simple’ house codes).

The second part of the code is the so-called ‘address’. Every address is a four-digit number
made up of the following 16 numbers: 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43,
44

Example: Address 11 22

This means that there are a total of 256 different addresses (16x16 = 256). The addresses are
divided into four address types (available number is in brackets):

• Single addresses (225)

• Function group addresses (15)

• Local master addresses (15)

• Global master address (1)

Each address consists of two parts. Part 1 is the ‘address group’, part 2 is the ‘subaddress’.

Example: Address 11 22 = address group ‘11’, subaddress ‘22’
