Sign of sound
July 1st 2009 New from Cirrus Research, the
Sound Sign is a highly visible, noise
activated warning sign designed for
use in environments where there is a
need to warn or indicate when a
designated noise level is exceeded.
Easy to install and operate, it is
controlled by setting a noise trigger
level and connecting the 12V power
supply to the unit. When noise
reaches the set level, the Sound Sign
illuminates and the warning
information can be clearly seen. More articles from Cirrus Research plc: |
