Note: The 4098-9794 Sounder Base and 4098-9795 Multi-Sensor Sounder Base
have a 9-position DIP Switch. The first eight DIP Switches set the
sounder base address. Dip Switch position 9 is set to OFF or ON
depending upon the sounder base power source. When the sounder base
is connected to a 24 VDC power source, DIP switch position 9 is set to
"OFF" and the 24 VDC power is supervised by the sounder base. When
the sounder base is powered by the panel's Notification Appliance Circuit
(NAC), DIP Switch position 9 is set to "ON" and the power is supervised
by the NAC and not the sounder base.
