OMEGAâ„¢ Model 70A Temperature Alarms are the latest development in solid state sound production. When power is applied, a piezoelectric transducer operates as a solid state oscillator resulting in a loud, audible alarm tone.
OMEGAâ„¢ Temperature Alarms are designed to give years of trouble-free service. There is no arcing or mechanical wear, and they are rugged and easy to install. Only a 1 1/8" diameter hole is required for mounting by removing the front plastic nut, inserting unit and rethreading. Units are easy to operate. Simply connect to a temperature controller and 120 volt ac power supply.
