12DC sounder with terminals, nickel-plated ring SP22-SDU-12DC. SP22-SDU-12DC\.

Sounder 12DC with terminals – reliable notification in your system

This 12V DC powered sounder is an ideal solution for visual and acoustic signaling systems. Designed to work with control buttons and indicator lights, it effectively informs about changes in device status or the need for intervention. Its versatility makes it suitable for both simple installations and more complex automation systems.

Construction and application

The SP22-SDU-12DC sounder has been designed as a complement to the SP22 (or ST22) series of control buttons. Its main task is to generate a clear audible signal with a frequency of 4-5 kHz and a volume of 80 dB. Thanks to this, even in a noisy environment, the sound is easily audible. Connection cables with a cross-section of 1…2.5 mm² (solid core) or 0.75…1.5 mm² (stranded) ensure a solid and safe connection to the electrical installation.

• Status signaling: Ideal for signaling alarms, warnings or confirming operations.
• Cooperation with other elements: Perfectly complements SP22/ST22 control buttons and indicator lights.
• Mounting: Compact dimensions make it easy to mount in limited space.
• Low energy consumption: Current consumption at 3 mA at 12 DC power supply minimizes the load on the power supply.

Key features and benefits

• Clear audible signal: A volume of 80 dB ensures effective notification even in difficult acoustic conditions.
• Universal power supply: Available versions for voltages of 9-12V DC, 24V DC, 24V AC and 230V AC allow adaptation to the existing electrical infrastructure.
• Solid construction: Ensures long-lasting and reliable operation in various environmental conditions (protection class IP20/IP30).
• Easy mounting: Connection cables facilitate quick and trouble-free connection to the electrical installation.
• Low power consumption: Minimizes operating costs and system power supply load.
