The same number of devices using 12 AWG wire will produce only 2 volts
drop. The same devices using 18 AWG wire will produce 8 volts drop.
Consult your panel manufacturer’s specifications, as well as SpectrAlert’s
operating voltage range to determine acceptable voltage drop.
Horn Selections
Horns are factory set for high volume, temporal code, and electromechan-
ical tone.
Tones:
Two tones may be selected using the jumper plugs located on
the printed circuit board. With the jumper offset, the tone is the
Electromechanical sound. With the jumper in place, the tone is
a 3 kHz sound.
NOTE: When powered from FWR supply, tones will be modulated (turned
on and off) by 120Hz causing the tones to sound different from DC power.
