SA-1A is a sound activated switch designed for applications where audio is required once a predetermined amplitude threshold has been exceeded. Additionally, the unit has two sets of relay contacts for activating cameras, lights, machinery or other annunciations. Automatic re-set is adjustable between 0.5 to 60 seconds. When used with Louroe Microphone and Base Station, the SA-1A is powered by the base station. As a stand alone unit (without a base station) 12 Vdc power is required.
