FIELD: physics. ^ SUBSTANCE: present invention relates to alarm devices for vehicles and is meant for giving out audio alarm signals. The multiple-function alarm sounder contains, in a single case, the first sound module (13), low frequency amplifier (15) and a loud-speaker (16), a photosensor (4) with an electronic switch (6) and the second sound module (11) - alarm pager, remotely connected to the case of the device, with buttons (12) for controlling the first and second sound modules (13, 11). The device also contains a switched attenuator (14) and a decoder (8) of external control signals with a single independent input and two extra inputs. The output of the decoder (8) of external control signals is connected to the first sound module (13), the output of which is connected to the first input of the switched attenuator (14), the second input of which is connected to the output of the second sound module (11), and the output to the input of the low frequency amplifier (15). ^ EFFECT: more functional capabilities and easier use of the alarm sounder. ^ 1 dwg |
