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/outdoor wall mounted field call station
The handset stations essentially consist of a handset with a noise canceling microphone, a keypad, a pre-amplifier, a telephone card, an interconnection card, station busy status indicator, a call indicating LED and ringer. Designed for indoor and outdoor wall / column mounting in industrial environments.
weatherproof canopy for field station
Outdoor weatherproof FRP canopy (250W x 250D x 660H) with handle, magnetic lock and mounting accessories for field call stations. FRP canopy with mounting accessories.
loudspeaker junction box
BNA loudspeaker is provided with a junction box - LSJB7201. The input to the LSJB's is paralleled with the inputs of other LSJB's from the Page line – 4 Way terminals of the Zone. The output is connected to output terminals of the 2-way terminal block for feeding the loudspeaker.
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.
