Candela Selections:
Figure 2: For strobe candela selection, adjust slide
switch located on the rear of the product while watch-
ing the viewing window on the side of the reflector.
NOTE: SpectrAlert selectable out-
put 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 this chart:
Horn selections using 3-position DIP switch on horn/
strobe (refer to Figure 3):
NOTE: When powered from a FWR supply, the horn will be mod-
ulated (turned on and off) by 120Hz causing it to sound different
than if powered by a DC supply.
High/Low Volume
ON=High Volume, OFF=Low Volume
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
