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.

Model SA-1A is a sound activated switch used in conjunction with the LOUROE ASK-4 #101 Audio Monitoring System or any of the AP Series non-alarming base stations. Usually located near the base station, the SA-1A provides a variable threshold level control that activates the microphone when that level is exceeded by a sound. In addition, it has 2 sets of relay contacts that automatically close when the threshold level is exceeded. This can be used to activate a camera, light or other annunciation. Automatic re-set is adjustable between 0.5 and 60 seconds. An alarm LED is illuminated during activation time. 12 Vdc Power is required.
