The SCE028LA3SU2B is a buzzer commonly found in security systems, fire alarms, smoke alarms and other warning applications. It is designed to generate short, loud sound bursts that are quickly recognizable as warning signals.

Application field

SCE028LA3SU2B is widely used in fire alarm systems, access control systems, as well as other safety and security applications. It can be usedalone, or combined with other types of alarm systems. In addition, its loud warning sound is ideal for signaling events, emergency situations, or alerting people of hazardous working conditions.

It is a widely used in commercial and industrial buildings, factories and warehouses. It can also be found in vehicles and boats, as well as in educational and residential buildings.

Working Principle

The SCE028LA3SU2B is a piezo-electric buzzer. This type of sounder works by generating an alternating current when a voltage is applied to its terminals. As a result, a mechanical diaphragm inside the device vibrates, thus producing sound. The loudness of the sound is determined by the frequency of the sound waves that are generated. The pitch of the sound can be adjusted to a specific frequency, and the operating voltage can be adjusted to match the voltage of the system in which it is installed.

The SCE028LA3SU2B is a versatile and reliable sounder that is easy to install and maintain. Its low cost and wide range of applications make it a popular choice for many alarm and security systems.
