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.
