The PK-20A25WQ is an audio device used in both commercial and industrial applications to provide robust sound warnings and notifications. It is an effective alarm system that uses an integrated sound sensor and simple power operation, providing reliability and durability wherever it is deployed. This application field and working principle will be discussed in the following.

Application Field

The PK-20A25WQ is an effective siren and is suitable for diverse security, construction, and residential applications. It is an ideal alarm solution for use in commercial or residential premises, such as a retail store, office buildings, or a family home. It is also a popular solution for larger sites, such as airports, shopping malls, and schools. Additionally, the device is waterproof and can be mounted onto a wall or pillar to ensure discreet installation and to minimize sound leakage.

The PK-20A25WQ is an effective alert system for a wide variety of applications, such as fire alarms, gas leaks, flood warnings, and emergency notifications. It provides a visible and audible alarm system that ensures people are alerted to any danger or alert condition. The device is useful for security purposes, such as a burglar alarm or access control system, and its 85 decibels of sound output are sufficient to alert people of any imminent danger or hazard in the area.

Working Principle

The PK-20A25WQ operates on a simple power-controlled system, meaning it requires only AC or DC power to function, with no other complex or expensive controls. It is designed to sense sound waves within its vicinity, and uses a built-in sound sensor to detect audible sound levels. As soon as the detected sound level is reached, the device is activated, and an audible alarm is generated.

Once the device is activated, the integrated circuit finds the correct frequency of the incoming signal and applies a voltage across the audio coil. This causes the sound coil to vibrate, producing the distinct tones from the device. The device can be customized to work with any input signal, such as a computer or telephone system, to trigger the alarm.

The PK-20A25WQ is also designed to be energy efficient. It is equipped with an automatic standby mode, which reduces energy consumption by up to 90%. This feature ensures that the device’s energy consumption is minimized when it is not in use.

Conclusion

The PK-20A25WQ is an effective and efficient alarm system that can be used in commercial and industrial settings. It is waterproof and discreet, allowing it to be mounted on walls or mounted on posts to minimize sound leakage. Its integrated sound sensor works by detecting ambient sound levels, and activating the alarm once these are exceeded. In addition, it operates on a simple power-controlled system and is designed to be energy efficient, ensured by its automatic standby mode. This makes the PK-20A25WQ an ideal alarm solution for any application.
