Alarms, Buzzers, and Sirens are a type of acoustic signaling devices that can emit sound for safety, alert, or warning applications. Among them, the MSR516WR is one of the more commonly known models, and its application field and working principle are described here.

The MSR516WR is used mainly in fire alarm systems, mass notification systems, medical signaling systems, evacuation signaling systems, and solar-powered LED flasher. This device is designed to reliably and quickly reach the required sound level and emit an output that can easily penetrate walls or other obstacles, maximizing its reach. Its various features make it suitable for a wide variety of applications.

In terms of its working principle, the MSR516WR produces sound when an electric current activates a transducer or speaker diaphragm that vibrates in sync with the current. This produces sound waves that are reflected off of solid objects and walls, creating a spatial acoustic effect. The speaker diaphragm used in the MSR516WR is constructed with a ferrite core, which eliminates resonance and other artifacts in the sound.

The sound output from the MSR516WR is also built to meet the latest acoustic alarm standards. These standards require the device to produce sound levels that are sufficient to provide an adequate notice to persons that are within a certain distance from the device. The MSR516WR is capable of producing sound levels of up to 113.5dB at 3m, with sound being projected at a frequency that is between 1.6kHz to 3.2kHz. This frequency is proven to be more noticeable than low-frequency sound wavelengths.

The MSR516WR is designed to operate on three power sources: a 9-42V DC battery, 110V AC, or 220V AC. This allows it to be used in a variety of environments, including locations where a consistent power supply is not available. Additionally, the device can be configured to work in either a single tone or dual tone mode. This feature allows the user to customize the sound output to suit their specific needs.

The MSR516WR also features a wide temperature range of -25°C to 70°C, allowing it to be used in both low and high-temperature conditions. In addition, the device has IP67 protection, making it dust and water resistant for reliable operation in all weather conditions. It also offers low current consumption, ensuring that its energy requirements are kept to a minimum.

Overall, the MSR516WR is a reliable and powerful acoustic signaling device, that is suitable for a wide range of applications. Its ability to produce sound at sufficient sound levels, flexibility of operation, and dust/water resistance all make it an ideal solution for any situation.
