2.6 Detecting a Sound Signal

Figure 22: Sound Signal as it is Detected

Figure 23: Sound Signal 3 sec. after Detection

When the Alphatron SSRS detects a sound signal and determines the direction of the signal, the direction will appear on
the display unit.

After 3 seconds the orange LEDs disappear and the red LEDs remain. The red LED indicator remains by default for 7
seconds or the configured amount of time.

Note The display timing (in seconds) can be adjusted from the web interface.
