The article is a buzzer from the manufacturer Eaton, type M22-XAMP, with manufacturer number 229028. It serves as an acoustic signaling device for industrial applications, particularly in conjunction with acoustic alarms of the M22-AMC series. The buzzer generates a pulsed tone, characterized by a rhythmic, intermittent sound sequence, to attract attention. It is designed for use in electrical installations where visual or acoustic warning is required, for example, during alarms, malfunctions, or operational states.

Applications

The buzzer is intended for use in industrial control and switching installations where clear, audible signaling is necessary. It is particularly suitable for systems with a nominal voltage of 24 V, commonly used in automation technology, manufacturing technology, or safety systems. The operating voltage ranges from 18 V to 30 V, enabling flexible integration into existing 24-V systems. The sound pressure level of 83 dB at a distance of 10 cm ensures sufficient loudness to be perceived in typical industrial environments.

Functions and Equipment in Detail

The buzzer operates at a vibration frequency of 2.3 kHz, corresponding to a high, penetrating tone. The current consumption is 30 mA, enabling efficient energy use while maintaining performance. The pulsed tone sound type provides a rhythmic, non-continuous sound emission, distinguishing it from continuous signals and improving perceptibility during prolonged signal duration. The black and silver color scheme matches the appearance of industrial control units.

Technology Explained Simply

The buzzer is powered by a voltage supply ranging from 18 to 30 V, with a nominal voltage of 24 V. Power supply is via terminal X1, where the positive pole is connected to X1. Electrical actuation is achieved via a digital signal that activates the buzzer. Sound emission occurs through a piezoelectric or electromagnetic transducer, which converts electrical energy into mechanical vibrations. The frequency of 2.3 kHz lies within the audible range and is suitable for good perceptibility.

Compatibility and Accessories

The buzzer is specifically designed for use with acoustic alarms of the M22-AMC series. It is therefore a replacement or supplementary part for existing alarm systems. Compatibility with M22-series alarms is ensured by the mechanical and electrical connection configuration.

Mounting and Installation

Mounting is carried out in the designated mounting area of the alarm unit M22-AMC. Electrical connection is made via terminal X1, with polarity to be observed (positive pole to X1). Installation does not require special tools or additional mounting materials. The installation dimensions and mechanical requirements conform to the standards of the M22 series.

Advantages in Operation

The use of the buzzer provides reliable acoustic signaling, which is also recognizable in noisy environments. The low current consumption of 30 mA reduces the load on power supply systems. Certification according to CE, UL, and CSA ensures compliance with relevant safety and quality standards. The operating voltage range of 18 to 30 V enables flexible integration into existing systems without requiring additional voltage converters. The pulsed tone sound type ensures clear differentiation from other signals, enhancing the reliability of signal perception.
