Sound Level Alert with Alarm
Built-in LEDs alert user when sound level is too high or too low
LEDs can be read from 30m (100ft)
Features:
• Ideal for industrial, hospital, auditoriums, schools and other
areas where there is a need for being alerted when sound level
reaches set point
• Meets ANSI Type 2 and EN 60651 accuracy specs compliant to OSHA
• User settable high or low limit (30 to 130dB) indication
with output to drive external relay module
• Microphone rotates 180° for desired placement.
Optional 5m (15ft) microphone extension cable for remote monitoring
• Complete with 100-240V AC 50/60Hz adaptor, microphone windscreen,
and built-in wall, desk and tripod mount (optional Tripod TR100)
Applications:
• Industrial, Hospitals, Classrooms, and special quiet zones –
When the sound level exceeds the HI set point the RED LEDs flash and
can be seen from 30m 100ft.
• Speakers/Educators/Instructors, Auditoriums and Theaters –
The user can set the SL130 so the RED LEDs flash when the sound level
is below the LO set point where people in the audience may not be able
to hear. When the sound level is above the LO set point, the GREEN
LEDs indicate the sound level is acceptable. The user can reverse the
Red and Green LEDs activation per user color preference.
