Alarm, buzzer and siren are all audible signaling devices use to alert against possible danger. Among them, PS2220P02 is a surge protected buzzer which is designed for all kinds of signal warning. It applies to all kinds of weak current circuit systems, such as electronic systems of voice warning, plane alarm systems, automobile alarm systems and so on.

PS2220P02 has a wide range of application fields. It has been widely used in fire detection alarm systems, fire control centers, security systems and home appliance products. Its audible sound coverage is up to 80 meters in area. The alarm can be triggered automatically by detecting the abrupt sound from the environment, and customers can select the sound level according to their needs. Furthermore, customers can switch in different languages according to their prefered tone for warning.

The working principle of PS2220P02 is solid-state. An electronic circuitry is housed within its housing. This circuitry is activated by electrical signals from the control device, which triggers an audible sound generated magnetically. This sound is directed through the housing and transmitted outside. The volume of the alarm is adjustable according to customers’ needs in the field.

Coupled with a solid-state buzzer element and its own adjustable current limiting resistor, the audible sound level is stable and the angle sound radiation is very good. An internal circuitry measures the start current, inhibit current and maintain current consumption. It can resist temperature, humidity, vibration and interference and provides more reliable performance in harsh environments.

Due to its unique design, PS2220P02 is especially suitable for and used in fault alarms, warning prompts, audio alarms, control alarms and process control devices. It offers a wide range of design flexibility and offers up to 5 hours of operation time without draining the batteries.

The PS220P02 buzzer is easy to set up and use, working quickly and accurately. Its adjustable current limiting resistor helps to limit the supply current to the buzzer, providing a more stable and higher sound output. It also features excellent sound radiation and low power consumption. In addition, its simple and beautiful appearance can be a perfect addition to a variety of products with high reliability and excellent performance.
