This multi-purpose sounder beacon from Clifford & Snell is an ideal solution for combined audio and visual signalling. Its housing is made of an acrylonitrile butadiene styrene (ABS) material that's durable and resistant to impact, so it's suitable for use in harsh environments. It's also flame-retardant for added safety. As the polycarbonate lens is ultraviolet (UV) stable, it won't be affected by sunlight when used outdoors. Thanks to its red colour and loud sound output of 112dB (decibels), it's a good choice for emergency signalling in noisy industrial environments.

• Xenon bulb provides bright light for high levels of visibility
• Low current consumption of 345mA (milliamperes) makes it energy-efficient
• Strobe light effect for an easy-to-see visual signal that's especially useful for oncoming trucks

• Emergency fire alarm systems
• Hotels and restaurants
• School classrooms

This sounder beacon has an IP66 (ingress protection) rating, meaning it's protected against dust and high-pressure water jets. While it shouldn't be submerged in water, it can withstand frequent exposure to moisture.
