Discriminator
The SLR 5000 Series Repeater’s Receiver audio will yield 330mV rms into 50 kΩ with an RF input
signal deviating at 60% RSD. With the community repeater panel’s own loading impedance, the
“Discriminator” signal delivered to the community repeater panel is at a high enough drive level to
leave the community repeater panel’s “Rx Audio Gain High/Low” switch in the factory default position
(back panel Switch 1).
NOTICE: Under the System Programming, turn on the DCS Rx data.
Tx Audio
The SLR 5000 Series Repeater’s transmitter will yield 60% RSD with 80mV rms into the Emph Tx
Audio port. The “Tx Audio” signal delivered by the community repeater panel is at a high enough drive
level to leave the community repeater panel’s “Tx Audio Gain High/Low” switch in the factory default
position (back panel Switch 4).
NOTICE: Under the System Programming, turn on the DCS Tx data.
Continuous Tone-Controlled Squelch Systems (CTCSS) Out
The SLR 5000 Series Repeater’s transmitter will yield 60% RSD with 80mV rms into the Tx Data port.
The “CTCSS” signal delivered by the community repeater panel is at a high enough drive level to leave
the community repeater panel’s “Encode gain high/low” switch in the factory default position (back
panel Switch 3).
Tx Audio Pre-Emphasis
Set the “Encode flat/ De-emphasized” switch to the Up position on the community repeater panel.
Carrier Operated Relay (COR)
For use with the SLR 5000 Series Repeater, configure the specified back panel switches on the
community repeater panel as follows:
• Switch 6 “COR source internal/external” (set to the Down position)
•
Switch 7 “COR polarity positive/negative” (set to the Up position)
• Switch 8 “COR pull-up on/off” (set to the Up position)
Phone Patch
Description
The SLR 5000 Series Repeater is capable of multi-mode telephone interconnect through the Zetron
Model 30 Phone Patch. The Zetron Model 30 Phone Patch interconnects to the SLR 5000 Series
Repeater and allow users to initiate and receive land line telephone calls via the subscriber radios.
When properly configured, subscribers can initiate and answer telephone calls.Via selective signaling,
calls from land line users can be directed to any subscriber or to a specific user. Additionally, access
control is also afforded by the Zetron Model 30 Phone Patch.
See Zetron Phone Patch Manual (supplied with the phone patch) for specifications, operation,
installation, alignment, programming, and repair information.
