DESCRIPTION
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.
