AR-25 Weatherproof horn loudspeaker is used as part of communication systems in Intercom and Public Address / General Alarm systems in the metallurgical, chemical, oil refining, gas and oil industries and industries similar to them in terms of application, as well as on railways.

AR-25 is designed to convert electrical signals into acoustic signals and emit them into the surrounding space (air environment). AR-25 is used to broadcast messages indoors and outdoors with severe operating conditions: when exposed to temperature and precipitation, the presence of aggressive chemical compounds and dust in the environment.
