Page Line Audio Detect Output Contact
The Model LE300-IP Line Extender provides a contact closure output that activates whenever audio is
detected on the page line. The contact can be set to close when audio is detected at the local page line, the
remote page line, or both. Typically this contact is used in conjunction with the Page Line Audio
Monitoring Output to provide a control contact to external devices or systems when page line audio is
present. The contact remains active for 1 second after the audio is no longer detected. DIP switch SW5
positions 6 and 7 enables or disables the output contact. Refer to Figure 6 for the location of switch SW5
on the Main PCBA and the tables below for setting options.

Page Line FSK Data Transmission (SmartSeries Systems)
A pair of Model LE300-IP Line Extenders re-generates the FSK data transmission between two
SmartSeries Page/Party
® system cables. FSK data transmission occurs on the page line allowing
SmartSeries Page/Party ® stations to communicate with the ADVANCE system control cabinet. For proper
operation, both line extenders must have this feature enabled by setting DIP switch SW5 position 1. Refer
to Figure 6 for the location of switch SW5 on the Main PCBA and Table 5 below for setting options.

enabled at the same time, neither feature will function correctly.
