RFS 070/2
RFS00702FAA000
Dual RF Sensing Switch
General Description:
The
RFS00702FAA000
RF Sensing Switch provides two (2x1) RF detector switches in a single RU enclosure. Each of
the RF sensing switches utilizes an DPDT RF relay to switch either the primary or secondary signal input to the output.
The pilot frequency is coupled from the primary signal input, filtered, amplified, and detected to operate the relay. When
the input level is above a preset threshold, which is adjustable using the front panel potentiometer, the relay is de-
energized and the primary signal path is selected. When the signal falls below the preset threshold, the relay is energized
and the secondary signal path is selected. A front panel slide switch has been included to allow manual override to the
secondary input. The rear panel has been equipped with relay contact alarm outputs and a remote override via contact
closure.
Note: Under a no power condition, the unit will default to the primary position.
