The siren Inferno behaves like a sound barrier, generating an intolerable and inoffensive sound that prevents intruders from staying in the protected area. Ideal to be used in combination with security systems in business, and high risk facilities. Compatible with any alarm system. Award-winning and stylized design to adapt it to any public or private premises. It incorporates internal battery against sabotage. The patented sound spectrum of Inferno makes it difficult to locate the origin of the sound source, as well as being highly irritating to the human ear. The Inferno sound generator creates, through a complex algorithm, 4 changing tones of different digital frequencies, which produce an effect of discomfort and disorientation on the brain when one can not distinguish the tone heard. These effects disappear immediately after the intruder leaves the protected space. They can be assembled together in series or parallel with other units. Selectable alarm time of 3 m. to infinity. Delay time from the shot that can be selected immediately or 30 s. Acoustic effect selectable by the user from 125-127 ± 1 dB at 1m. Coverage of approximately 70 m2 or 150 m3 for each Inferno siren. As a comparison, two Inferno barriers adjusted to 125 dB produce the same acoustic effect as 28 analog sirens of 115 dB. Elegant and robust external housing in aluminum and steel protected with tamper. Frequency range from 2 to 5 KHz. Ni-MH reserve battery 9.6 V / 1.800 mAh. Estimated battery life 3 years. Autonomy at rest of the internal battery for more than 2 months. 12-16 Vdc power supply. Consumption less than 150 mA. Dimensions: 685 x 106 x 40 mm. Weight: 1.7 kg.
