BeskrivelseThe 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.
