5.5. FS-7000AT Attenuator Control Panel
The FS-7000AT is used in conjunction with FS-7000 Series Voice Evacuation Systems to control 4-wire
system attenuators. Up to 10 zones can be attenuator-controlled. When general urgency or emergency
broadcasts are made, the FS-7000AT provides 24 V DC power to allow such broadcasts to bypass the
attenuators. The output status of each line can be monitored by the indicators on the front panel.
