Multi-tone sirens: Signal effect with multiple tones
With electronic sounders, the audible signal is generated electronically and, depending on the size of the signaling device, is then output via sound capsules, pressure chamber loudspeakers or classic loudspeakers. Auer Signal multi-tone sirens offer up to 63 different tones and maximum sound for all the different sounds. Simply select clearly distinguishable signal tones for your area of application, to which different meanings and actions are assigned.
The size of our models varies depending on performance. In our product range you will find multi-tone sirens in the sizes 30 to 132mm. The mounting of the devices is as simple as it is versatile: horizontally, vertically, on a pole or with an angle for wall mounting.
ASX – the loudest multi-tone siren
The ASX multi-tone alarm soudner from our A Series is the loudest multi-tone sounder on the market with a sound pressure of up to 127 dB. The user has a choice of 63 tones, three of them are externally controllable. The square multi-tone siren of the A series convinces even in smaller sizes with their loud performance. For additional optical signaling, the series A models can be combined with lights from the M22 series or the Q series.
Piezo buzzer: Small size, enormous sound pressure
Despite their small size, piezo buzzers generate frequencies of up to 4000 Hz and also have low power consumption. The piezo crystals, which are attached to a brass disc, generate a sound under voltage. The loud ESG panel mount buzzer generates a volume of 85 to 105 dB, which is smoothly adjustable. In addition, three easily distinguishable tones are available to the user.
