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.

Temp/Non-Temp ON=NON-Temporal, OFF=Temporal 3KHz/Electromechanical ON=3KHz, OFF=Electromechanical

WARNING

Check terminal polarity before wiring. For proper operation, make sure the correct wire polarity is applied to the unit.
