Line Connection Relays
The Model LE200 has relays that disconnect the page and party line connections from the main PC board
for special applications. This would apply to single party line systems or any application in which a
page/5-party cable is not connected to the line extender. The DIP switch, SW4, controls audio line
connections. Also, if no Page/Party
®
cable is connected, DIP switch SW6-4 should be closed to mute the
analog circuits.
N
OTE
: When a party line is disconnected from the field wiring, that party line’s off-hook detector should
be disabled. Otherwise, that party line will appear permanently off-hook.
