Introduction
TLS RF Wireless System Site Layout
TLS RF Wireless System Site Layout
Figure 1 illustrates an example TLS RF Wireless System installation. The Repeater component may be required if
the system Receiver, mounted on building’s outside wall, has difficulty receiving signals from any of the
Transmitters. See page 30 for Repeater installation.
