The Louroe Electronics SG-1 Hand-Held Sound Generator is designed for assistance in setting the threshold levels for sound activated audio monitoring systems involving the ALA and DG Series Alarming Base Stations. It generates 77 dB sound pressure level at 3', and 3,560 Hz at 9V battery source. This generator emits 3 kHz tone.
The SG-1 is a reference device only, and does not dramatize the actual ambient sound in a sound activated audio monitoring application.
Made in USA
