24AC sounder with terminals – reliable warning in your system

The SP22-SDU-24AC sounder is a signaling element that perfectly complements control panels and alarm systems. Designed to work with SP22 control buttons and indicator lights, it finds application wherever a clear audible signal is needed. Its solid construction and universal supply voltage make it an ideal choice for both professional installers and end users.

Construction and application

The SP22-SDU-24AC sounder generates a continuous sound signal with an intensity of 80 dB in the frequency range of 4-5 kHz. Thanks to this, it is audible even in environments with increased noise levels. Primarily intended for signaling systems, it informs about the status of the device or alarms in the event of irregularities. The possibility of connecting wires with a cross-section of 1…2.5 mm² (solid) or 0.75…1.5 mm² (stranded) ensures easy integration with the existing installation.

Key features and benefits

• Clear signal: A volume of 80 dB guarantees effective warning even in a noisy environment.
• Universal power supply: Available power supply versions AC (24V, 230V) and DC (9-12V, 24V) allow adaptation to different installations. In this case, the model operates at 24V AC.
• Easy installation: Compact dimensions (29 x 42.90 x 23.4 mm) and connection terminals facilitate installation and integration with the system.
• Solid construction: Made of high-quality materials ensures long-lasting and reliable operation.
• Protection class IP20: Provides basic protection against contact and ingress of solids.
• Low power consumption: Power consumption at 7.5 mA at 24AC power supply minimizes the load on the electrical installation.
• Compatibility: Perfectly matches the series of control buttons and indicator lights SP22 by SPAMEL.

The SP22-SDU-24AC sounder is characterized by a supply voltage of 24 V AC, generates a signal with a carrier frequency in the range of 4-5 kHz and reaches a sound intensity of about 80 dB. Wires with a cross-section of 0.75 to 2.5 mm² can be used for connection, and the degree of protection is IP20. The power consumption is 7.5 mA at 24AC power supply.

The SP22-SDU-24AC sounder is a practical solution for any system requiring reliable audible signaling – from simple control panels to advanced alarm systems. Its versatility and ease of installation make it an ideal choice for both professionals and home users.
