5.0 TYPICAL INSTALL
The A 4205 loop amplier is designed to work with small installs where the coverage required is around 1m. It is ideal
for ticket booths, reception desks, information booths etc. The loop can be installed in a vertical axis such as illustrated in
gure 4 where the loop is attached to the back of the interview screen. A preferred installation is shown in gure 5 which
provides a loop which works on both the vertical and horizontal axis. In both installs the loop length is around 3.5m in
total with a total resistance of 0.2Ω to 1.7Ω (max 2Ω). Twist together the tail wires that don’t form part of the loop.
Fig 4. Loop is installed on the back of the interview screen on the vertical axis.
Fig 5. Loop is installed under the desk on both the vertical and horizontal axis.
