System Sensor SpectrAlert Ceiling Mount Series Strobes and Horn_Strobes User Manual

Horn Selections
The horns on SpectrAlert horn/strobe combo units are fac-
tory set for high volume, temporal code, and electrome-
chanical tone.
Tones:
Electromechanical or 3kHz tones may be field-selected
using the DIP switch selector (See Figs. 2B and 3B for
DIP switch location).
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.
Temp/Non-Temp:
Temporal coding or Non-Temporal coding can also be
field-selected using the DIP switch.
High/Low Volume:
High or low volume may also be field-selected using
the DIP switch.
