Alarms, Buzzers, and Sirens
Alarms, buzzers, and sirens are devices used to alert people of an impending danger or other important event. They may be audible, visible, or both, and typically consist of several components, such as a trigger, a power source, and a sound or light source. Among the most common types of alarms are fire alarms and car alarms, which are often activated in response to a threat, such as a fire or an attempted theft.
SMT-831-2 application field and working principle
The SMT-831-2 is a dual frequency alarm sounder designed for use in commercial and industrial applications. It can provide an audible alert for a wide range of applications including fire, security, emergency, and industrial alarm systems. The device is capable of producing two sound frequencies, a high frequency of 4200 Hz and a low frequency of 2800 Hz. The two frequencies may be heard separately or together. The SMT-831-2 is powered by an external low voltage DC supply typically ranging from 6V to 24V DC, and draws up to 4 watts of power. The output of the SMT-831-2 is a directional sound beam that can be focused in a preferred direction by the user. When in operation, the SMT-831-2 produces a loud, clear, and distinct sound over a distance of up to 50 meters.
When triggered, the SMT-831-2 sounder begins to emit sound at a slow rhythm of one tone per second. The sounder can be set to one sound frequency or both sound frequencies together. The sounder also has the ability to increase the rate of sound signaling in response to an alarm. When the sound intensity reaches a certain level, the sounder automatically switches back to the base intensity of one tone per second. The SMT-831-2 is designed for both indoor and outdoor use and is highly resistive to environmental elements, including dust, water, and extreme temperatures.
The SMT-831-2 is a cost-effective alarm sounder with a wide range of applications. Its advanced features make it perfect for the most demanding alarm systems, and its robust construction makes it an ideal choice for tougher, industrial applications. Its features include:
- Highly audible sound for up to 50 meters
- Dual frequency sound output
- Double-dependent mechanism to adjust sound intensity in response to alarm conditions
- Protective housing for outdoor use
- Low power consumption
In addition to its wide range of applications, the SMT-831-2 is an ideal choice for those requiring low cost, effective, and reliable sound alarms. It is easy to install and maintain, and is designed for user convenience and long-term use. The SMT-831-2 is a perfect choice for a wide range of alarm systems and industrial applications.
