SATEL SOW-300 BL Indoor Optical-Acoustic Signalling Device with Blue LED Strobe, 12V DC, 100 dB

The SATEL SOW-300 BL is an indoor optical-acoustic signalling device that delivers a powerful 100 dB alert at one metre, combining a piezoelectric sounder with a highly visible blue LED strobe to ensure every alarm event is both heard and seen.

Advantages

Built to meet EN 50131-4 Grade 2 requirements, the SOW-300 BL offers reliable operation across a wide temperature range. Its low current consumption — just 40 mA at 12 V DC — makes it easy to integrate with existing alarm control panels without overloading the system. The surface-mounting design and ABS plastic enclosure simplify installation and ensure long-lasting durability. Additionally, the built-in tamper protection guards against unauthorised opening or removal, providing an extra layer of security.

Suitable for

• Indoor alarm systems in residential and commercial properties
• Security installations where both audible and visual alerts are required
• Integration with intruder alarm control panels supporting 12 V DC signalling devices
