Using a #15 torx driver, open the covers of the TLS RF, Repeater and Receiver. Make a temporary ac power
cord with a grounded plug on one end. Connect the ac power cord to the TLS RF’s input power terminals and
ground terminal (refer to Figure 6 and Figure 7). Connect a necessary length of RS-485 cable from the TLS
RF’s RS-485 terminals to the Receiver’s RS-485 terminals (refer to Figure 21). Connect a necessary length of
2-conductor cable from the Receiver’s Repeater terminals to the Repeater’s Repeater terminals (refer to
Figure 22).

The steps below are to verify the communication between the TLS RF Unit and the Receiver.
a. Plug the TLS RF’s ac power cord into a 120 Vac outlet. Confirm the Green /Red LEDs (refer to item 2 in
Figure 12), are flashing rapidly. This is an indication there is RS-485 network activity between the TLS RF
and the Receiver.
b. If it is, continue to Step 6.
c. If it is not, check PWR LED (refer to item 3 in Figure 12), if not lit; check power wiring. If the wiring is
correct, measure the voltage across the twisted pair power wires, it should read +15Vdc. If it is not, the TLS
RF is bad.

Pay close attention to the polarity of the +15 Vdc. Revers-
ing the connections can cause damage to the TLS RF.
