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 600
W
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.
