The SHADOW series is renewed by important and significant updates that make the range perfect for all
installations where high intelligibility of alarm messages and excellent sound reproduction are required. All
speakers of the new SHADOW series feature an IP55 and, due to their structure made of self-extinguishing
polypropylene with UL 5VB flammability rating, are now certified according to EN54-24 standard. All models of the
series have a ceramic terminal block and thermal fuse installed inside to guarantee the protection of the
loudspeaker connection line in case of fire. Moreover, all connections consist of fire retardant wires that comply
with EN50200 standard (with IP68 hermetically sealed cable gland).
Curves and rounded edges of the shadow speaker reduce acoustic reflections and standing waves inside the box,
improving low-frequency performance; they also keep water from settling on the covering and wind diffraction.
The SHADOW series was designed primarily to provide extreme water resistance. Therefore the metal protective
grid was also designed to meet this requirement. The grid consists of three layers with an external stainless steel
perforated metallic part treated with a special protection, a central layer with cross-linked foam and a layer formed
of a special waterproof polyester mesh.
