Alarms, Buzzers, and Sirens are commonplace in a variety of applications.A particular such product, the SCE120MA2DP2B, is found among a range of alarms, buzzers, and sirens specifically designed for specialized applications. In this article, we will investigate the application field and working principle of the SCE120MA2DP2B.

Application Field

The SCE120MA2DP2B has been designed primarily for use in potentially hazardous environments where escape and surveillance detection is of the utmost importance. Primarily found in construction, industrial, and mining settings, these alarms, buzzers, and sirens are designed to attract attention and alert personnel in the area of the potential hazard. This product is also suitable for use in communication alarm, door alarm, and fire alarms.

A significant benefit of the SCE120MA2DP2B is its low power consumption. Due to the nanoampere-level quiescent current value and low duty cycle frequency, it eliminates the need for cumbersome wiring and external power sources. This in turn leads to greater cost efficiency and easy installation for organizations considering this product.

Working Principle

The SCE120MA2DP2B is a piezoelectric device that uses vibrating crystals to generate sound. Its built in piezo ceramic crystal uses frequency modulation to produce sound at a predetermined frequency. It operates at a frequency of 2kHz and produces a 25-decibel minimum audible sound level. Its mechanical design helps minimize the mechanical noise caused by shock or external vibration.

The product is designed to be installed on flat surfaces with a temperature range of -10℃ to 85℃. It requires a voltage range of 10 to 35 Volt DC to operate, with a current usage of just 20mA. Unlike other sirens and alarms, this product can be mounted horizontally or vertically to suit the application. It also boasts a 5 to 10 meter distance of detection for maximum efficiency.

Conclusion

The SCE120MA2DP2B is a unique alarm, buzzer, and siren designed specifically for use in potentially hazardous environments. Its low power consumption, combined with its frequency modulation technology, makes it suitable for a wide range of applications, including communication alarm, door alarm, and fire alarm systems. Its rugged construction, versatility, and ease of installation make it the preferred choice for organizations looking for reliable and cost-effective alarm solutions.
