HC-79 24V Warning and Alarm Light with 105dB Sound and Strobe Flash

This compact warning light is engineered for safety-critical signalling in commercial and industrial environments, combining a piercing 105dB audible alarm with a high-visibility strobe that flashes up to 120 times per minute. Operating on a flexible 12V or 24V DC system, the HC-79 model is suited for integration into existing fire safety and hazard warning setups within enterprise buildings, communities, and other facilities requiring reliable auditory and visual alerts. Its construction prioritises longevity, with a service life rated for over 1000 hours of continuous use under standard power conditions, making it a durable component for ongoing safety protocols.

Features and Construction

The HC-79 warning light delivers a multi-sensory alert system designed to be noticed. Its core functionality pairs a bright, flashing strobe with a distinct audible tone, ensuring warnings are received even in noisy or visually busy environments.

Material and Build

The unit features a robust plastic housing designed to withstand the environmental conditions typical of industrial and building installations. The included mounting base and screws are constructed from metal, providing a secure and stable attachment point to walls, machinery, or vehicles. This material selection focuses on impact resistance and secure installation rather than aesthetic appeal, aligning with its primary function as a safety device.

Size and Practical Fit

With dimensions of 73mm in diameter and 45mm in height, the light maintains a compact profile. This size allows it to be installed in locations where space is constrained, such as above doorways, on control panels, or alongside other equipment without causing obstruction. The modest footprint contributes to its versatility across different application sites within a building or facility.

Uses and Placement

This product is specified for professional and institutional use where clear, unambiguous signalling is a necessity. Its application is driven by safety regulations and the need for immediate occupant awareness.

Event or Professional Use

In enterprise buildings, the light can serve as part of a fire alarm evacuation system, providing both flashing light and sound to guide occupants. Its 24V compatibility makes it suitable for integration with industrial control panels, security systems, or vehicle-mounted warning setups on site vehicles or maintenance equipment. The available colour options (red, yellow, blue, green) allow it to conform to specific colour-coded signalling standards, such as red for fire alarms or amber for caution.

Everyday Home Use

While designed for commercial applications, the low-voltage operation and simple wiring make it a potential component for advanced DIY home security or workshop hazard alert systems. However, its primary design and decibel level are oriented towards environments larger than a typical domestic setting.

Benefits and Buying Value

The value of this warning light lies in its reliable, dual-output signalling and its build quality suited for long-term installation.

Reuse and Low Maintenance

The product is built as a fixed-installation device. Its rated service life of over 1000 hours under continuous standard power suggests a component designed for sustained use rather than frequent replacement. Maintenance is minimal, primarily involving periodic functional checks of the strobe and alarm to ensure they activate as expected.

Why Choose This Product

This unit offers a concrete combination of features: a specific 105dB alarm volume, a defined flash rate, flexible voltage operation, and a compact size. For buyers seeking a warning light with these precise, measurable specifications—particularly for 24V systems or where a specific colour is required—it provides a defined solution. It avoids vague claims of performance, instead detailing its operational parameters, which allows for informed integration into a planned safety system.
