Description
Electronic part 
All electronics of a siren the BABOON is mounted in a tin case from stainless steel. For prevention of access and management of a siren, the case is equipped with two locks and the door sensor connected to the control panel. In case of very exacting application there is a possibility of addition with special cases with additional protection against influence of weather conditions. 
The kernel of a siren consists of the module of management, the module of amplifiers (power of one amplifier makes 2 x 150W) and the power supply with BP of accumulators. Electronics of a siren is connected to two to 12V accumulators which are not demanding service which receive recharge from a network 220V. Power of accumulators depends on the number of the used amplifiers, that is on siren power. Accumulators, standardly, ensure functioning of a siren for 72 hours, after shutdown of supply of electricity. Thanks to optimum use of electric energy, it allows to ensure functioning from solar batteries. 
Acoustic part 
The acoustic radiator consists of a vacuum loud-speaker and a hyperbolic loudspeaker like "horn". The loud-speaker and loudspeakers are adapted for transfer of radiation of typical acoustic signals of the classical motor rotational sirens imitating sounding. In this frequency range the largest acoustic pressure is reached, and this most range of sounding of a siren increases. 
Radiators, as a rule, settle down in pairs on metal columns. There is a possibility of application and a different way of an arrangement for the purpose of achievement of various characteristics of radiation. Beginning from almost circular, then and finishing ellipse purposeful. 
Loudspeakers are made of the special, aluminum alloy allowing to increase as much as possible their firmness, and weight to make minimum. They, practically, are always established in an exterior on a height and are exposed to direct influence of weather conditions (the sun, a rain, snow, wind...), and it is frequent also insects (wasps, bees...). Experience of use of plastic loudspeakers shows that their durability, in so exacting conditions which are necessary for use of sirens is very limited, and expenses on their service and replacement, considerably exceed expenses on use of aluminum. It should be noted that vacuum loud-speakers are developed so that their maximum firmness and big power was provided. 
For installation of loud-speakers, the Telegraphy association developed several types of masts which can be established on various types of roofs, and also various columns. Masts are designed so that their installation, I include loudspeakers, there was the most simplified also at the same time providing firmness for standard use. All types of masts were statically calculated and approved.
