DESCRIPTION

The SA-1A is a sound activated switch, based on sound pressure level, that can be used with the Louroe

ASK-4 Kit 101, any Louroe base station or as a stand alone with any Louroe Microphone. The SA-1A

provides an adjustable threshold that activates when the microphone is subjected to a noise or sound

that exceeds the set threshold level.

The unit has two sets of NO/NC relay contacts for activating a camera, light, machinery, etc. A Louroe

base station is used if sound (audio) is to be monitored or recorded. The SA-1A can accommodate a

10K balanced or 10K unbalanced input. All Louroe microphones produce an unbalanced 600W line level

output.

The length of release latching time can be set from 0.5 to 60 seconds. A built-in LED illuminates when

the threshold setting has been exceeded and the unit is triggered.
