ZA120SADT7 application field and working principle

ZA120SADT7 is a type of sound and signal device widely used in various occasions to provide sound and prompt warning. Its structure is simple but elegant in shape, and its sound and signal characteristics are reliable. It is mainly used to provide sound and signal alarms for a variety of electrical control control and alarming equipment.

This product is mainly used in fire alarm, burglar alarm and other safety monitoring systems. The product’s simple volume adjustment technology makes it one of the most reliable and cost effective safety alarms for monitoring systems. In addition, this product is suitable for use in public occasions such as schools, hospitals, airports and other sound and signal alarming systems.

Working Principle: The ZA120SADT7 alarms, buzzers and sirens use an electronic circuit combined with a piezoelectric buzzer, which is composed of two winding coils and a movable magnet. When the power is turned on, the voltage in the circuit drives the coil to generate an alternating magnetic field. The alternating magnetic field drives the magnet to rotate quickly. The rotating magnet drives the piezoelectric buzzer, and the mechanical vibration generated by the magnet is amplified by the piezoelectric buzzer to produce a high-decibel sound. The volume of the sound and its frequency can be adjusted and customized based on the number of coils used.

Advantages: First, the volume and frequency of the ZA 120SADT7 alarms, buzzers and sirens can be adjusted or customized by using different number of coils. Secondly, sound produced by this type of device is louder and more stable than the conventional sirens. Moreover it is very lightweight, and consumes low power as compared to other types of alarms, buzzers and sirens.

Disadvantages: One major disadvantage of this type of sound and signal devices is that they can produce sound at very high dB levels, which can be harmful for human ears. Secondly, they cannot withstand the shock and vibration conditions which are common in some industrial applications.

Conclusion: Alarms, Buzzers and Sirens are widely used in various applications to produce sound and prompt warning for security detection systems. The ZA120SADT7 type of product is a powerful, stable and cost-effective sound production device, which can be adjusted and customized to produce both higher and lower volume levels. Although these products can be very loud and can cause damage to human ears, they are still widely used in various alarm systems.
