Fire alarm ABT-P10, ABT-P10P loudspeakers have been designed and manufactured for the most demanding customers as well as to meet the
requirements of the most complex and sophisticated sound transmitting applications.
Thanks to the contribution of advanced technologies they combine excellent acoustic
parameters and high aesthetics with resistance to mechanical damages and varying
weather conditions as well as low prices. Their additional quality is an exceptionally quick and simple installation. Quality standards and audio characteristics
have been confirmed through tests and trials in an anechoic chamber, resistance and integrity testing equipment, as well as chambers for resistance to weather and air humidity testing. The need to maintain the best acoustic parameters was the idea underlying the design process. ABT-P loudspeaker models emitting the
sound which features directional characteristic and high efficiency. 5-inch 2-cone wide band loudspeakers used in these series are excellent alternative solution for horn-type units due to wide frequency band. They prove excellent in both musical and verbal applications. ABT-P10 and ABT-P10P loudspeakers are
enclosed in round casings made of resistant and durable ABS; they feature a high class of protection from humidity. Thanks to directional characteristic of sound propagation our loudspeakers are mostly applied on circulation routes and in wide area sound emission. Due to resistance to weather conditions the loudspeakers
prove excellent in industrial halls, warehouses, as well as partly open spaces
exposed to outdoor weather conditions. Apart from high mechanical and functional
resistance ABT-P loudspeakers entirely comply with global requirements for systems, including also the British Standard No. BS5839 Part 8 and EN 54-24.
All ABT-P loudspeakers have built-in a ceramic connection block and a thermal fuse. Two sound-transmission cable penetrations in the casing are insulated by means of two cable glands. Inside the fire zone the loudspeaker is isolated from the entire line, which ensures line continuity and uninterrupted broadcasting of emergency messages. The individual power rating is selected by means of connection
with applicable transformer branch. ABT-P loudspeakers are designed for continuous
operations at rated parameters for at least 100 hours in compliance with the IEC-268-5 Standard. ABT-P10P loudspeakers are designed for pendant mounting. They are equipped with an additional junction box enabling simple and quick speaker installation. They are used wherever the distance from ceiling mounted speaker is too large.
