Outdoor sirens

 

— devices designed for use outdoors or outdoors (or in rooms where the climate is not particularly different from the outdoors). When used in this way, the siren is exposed to a number of adverse effects - high and low temperatures, sunlight, precipitation, dust, etc. Street models are characterized by a high degree of body protection, allowing them to withstand the mentioned “troubles” without consequences. However, it must be taken into account that the specific range of protection, operating temperature and humidity may vary.
