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.

The M22 Series panel mount signaling alarms are made of heavy-duty industrial, UV stabilized polycarbonate and are intended for indoor or outdoor use. They are UL Type 4/4X/13 and IP65 approved for harsh environments and are watertight. The M22-30K models are specifically designed for the food industries and have fully enclosed housings to prevent contaminates from accumulating. The M22 series alarm sounders are equipped with a plug-in three point finger-safe terminal block for ease of wiring and configuring the tone type. All M22 models can be configured for either continuous or pulsing tones. The M22-65G models can also be wired for a wobble tone (alternating frequency). Users may also adjust the intensity of the sound levels on the 45 and 65 mm (1.8 and 2.6") alarm models.
