High Frequency Sonalert Module

Model 80223HM


A single frequency tone for simple auditory signaling. Use with 80223M for two tone applications. For single tone applications use 80223M.


This module provides an alternative stimulus to the standard 80223M unit. It produces a second fixed high frequency tone for simple auditory discrimination studies, and is mounted on an identical standard (2U) modular panel. This unit is compatible with the 80004, 80004NS and the 80004TS Modular Test Chambers. Although the frequency is fixed, the volume may be adjusted with a manual cover shown here.
