5-Year Limited Warranty
The Model 8143 Signal Selector/Distribution Amplier detects
failure of either input signal and provides manual or automatic
switchover between two frequency sources. The selected input is
distributed via 12 buffered output line drivers. In the automatic
mode, Channel A is selected when it is present. Switchover occurs
when Channel A is removed, when an alarm is sensed, or when a
manual selection is made. In manual mode, switchover is operatorcontrolled.
