System Sensor P1224 and S1224 - Manual (Page 3)

NOTE: SpectrAlert selectable output strobes, set at 15 and 15/75cd,
automatically work on both 12V and 24V power supplies.
NOTE: The strobe is not listed for 12V operating voltages when
set to 30, 75 or 110 candelas. Use only those settings marked as
OK in the chart above.
NOTE: The low volume setting of some tones must NOT be used
for public mode applications when the device is powered from a 12-
volt panel. Refer to the Sound Output Guide on the previous page.
