Sirens

Piezo and motor sirens

Signal sirens

Signal sirens are widely used in alarm notification systems. Due to their high volume, they are used to attract attention. Another application is in industrial environments for signaling the completion of a process, work cycle or signaling in the event of an accident, fire or other extreme situation or danger.

Types of sirens

Emergency and signal sirens as a technology are mainly divided into:

Piezo siren

The piezo siren is an electronic device that uses the piezoelectric effect, a mechanical voltage, to generate sound waves. The main components of a siren include a dielectric that, when subjected to voltage, begins to vibrate and emit sound waves.

Piezo sirens are known for their high level of sound emission and are often used in alarm systems, industrial machinery, and various electronic devices for signals and alarms./p>

Motor siren

Motor sirens are a type of alarm device that uses a mechanical motor to generate sound. They use the motor to drive a rotating disk that creates sound waves through friction or resonating components.

Motor sirens can generate extremely loud and carrying sounds that are effective in attracting attention over long distances. Extremely suitable for use in emergencies, dangers and disasters.

Siren supply voltage

Depending on the application, when choosing a signal siren, you can choose a supply voltage such as:

 

• 5 VDC
• 12 VDC
• 24 VDC
• 230 VAC
