power distribution box
BNA Power Distribution box has facility to create multiple power lines. 1 input power and Minimum 5 power output loops can be created. MCB is provided for extra protection. Enclosure material is industrial grade LM-6 having ingress protection IP-65.

indoor/outdoor horn type speaker
Weather Proof horn speaker for Industrial, Commercial, Security Applications. BNA high quality, weather proof horn speakers are compact, light weight, rugged and molded in tough ABS plastic. The specifications and construction of these are similar to the low impedance horn speakers. These models have been provided with 100V line matching transformers with multiple taps / impedance at the rear of the sealed assembly. These 100V models are ideal for installations where long speaker cables are used to avoid power loss in the cables. IP-65 is provided against foreign particles such as dust and jets of water, thus making them ideal for outdoor use.

indoor cone type speaker
BNA's industrial speaker units are designed to provide optimum performance in industrial applications. These indoor cone speakers are used in Power/ Steel / Petrochemical and process plants with high ambient noise, corrosive environments.
