1. Polarity shown in active state at terminals 1 and 2 of SBGA-34 and 1+, 1-, 2+ and 2-
of FS-250/FS-250C NAC cirucits. Proper polarity must be maintained or audible
base will not operate properly. Each audible base must be tested to verify operation.
2. Tone selection (refer to page 7 for more information).
3. SBGA-34 terminals 5-8 are polarity insensitive. Line 1 and Line 2 can be either line
of the loop.
4. SBGA-34 shown Style Z (Class A). It may also be wired as Style Y (Class B).
5. FS-250/FS-250C Notification Applicance Circuits (TB12 and TB13) provide 4
outputs that can be configured for Class B or two outputs that can be configured for
Class A. Refer to the FS-250 Operation, Installation and Maintenance Manual, P/N
315-049353, or the FS-250C Operation, Installation and Maintenance Manual, P/N
315-049589C, as applicable, to set jumpers JP1-4 for Class A or Class B operation.
6. EOL resistor, 24k ohms, ½ watt, 5%, P/N 140-820405.
