Loud Tone -95 dB @ 2900 Hz

Solid State Reliability, No Arcing or Mechanical Wear

Easy to Install

Very Low Cost

OMEGA? 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. 

OMEGA? 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.

Humidity

Model 70A Temperature Alarms will operate after having been subjected to 95% relative humidity at 40°C continuously for 100 hours. After removal from high humidity, the unit should be allowed to dry for a minimum of four hours at room temperature before operation.
