The SL20 is a single rack space Sound Pressure
Level meter with special triggering circuits.
When monitored sound exceeds a specified level,
a relay connected to a
switched output
is activated. The
switched output
can then
activate connected ancillary equipment
which can be used to notify the manager, light a
light, ring a bell, or activate a compressor. It
can even be used to activate a counter to
determine how often sound exceeds the specified
level. The choice of ancillary equipment is made
by the installer to accommodate the particular
situation. The SL20 does not contain audio attentuation circuitry, only triggering
circuitry. Triggering Circuit:
This circuit will respond when the SL20 monitors
a sound which is over the user's specified
level. A switched output control relay and an
audio attenuation circuit will be triggered.
Switched Output Controls: The
SL20 provides a rear panel mounted
terminal strip to which an installer can connect
ancillary equipment suitable for the
installation. This terminal strip becomes
"active" when the switched output control relay
is triggered. Connected equipment can range from
a simple light bulb to a heavy duty solid state
relay capable of handling multiple announcement
devices. |
