HC-79 24v Warning Alarm Light with 105dB Sound and 120 Flash/Minute Strobe for Building Security

The HC-79 warning light from Ji'an Electronics provides reliable emergency signalling through combined audible and visual alerts. Designed specifically for building complexes and community fire protection applications, this compact unit delivers clear warnings with its dual-mode operation. Available in multiple colour options and compatible with standard 12v or 24v DC power systems, it offers flexible integration into existing security infrastructure without requiring extensive electrical modifications.

Technical Specifications and Performance

The HC-79 warning light combines measurable performance metrics with practical installation flexibility. With clear technical parameters provided by the manufacturer, users can accurately assess how this unit will perform within their specific security or warning systems.

Power and Electrical Operation

Operating on either 12v or 24v DC power, the HC-79 provides voltage flexibility for different installation scenarios. The working current varies between 50mA and 30mA depending on the selected voltage configuration. This dual-voltage capability allows the same warning light model to be deployed across facilities with different power standards, simplifying inventory management and installation procedures.

Alert Output Specifications

The unit produces an audible alarm reaching approximately 105dB, creating an unmistakable warning sound in emergency situations. Simultaneously, the integrated strobe light flashes at speeds up to 120 times per minute, creating a highly visible visual alert even in brightly lit environments. This combination of sound and light ensures comprehensive warning coverage for various emergency scenarios.

Physical Dimensions and Build

With compact dimensions of 73mm in diameter and 45mm in height, the HC-79 warning light offers space-efficient installation possibilities. The modest footprint allows mounting in various locations without obstructing walkways or creating visual clutter. The design accommodates the necessary electronic components while maintaining a practical size for most warning light applications.

Installation and Application Scenarios

Designed primarily for building and community security applications, the HC-79 warning light serves specific emergency notification purposes. Its technical specifications support reliable operation in the environments where clear, immediate warnings are most critical for safety and coordination.

Building and Community Fire Protection

The manufacturer specifically indicates building community fire protection as the primary application scope for this warning light. In these environments, the combination of loud audible alarm and rapid visual strobe helps ensure that emergency notifications reach occupants throughout the facility. The multiple colour options allow different alert types to be visually distinguished when multiple warning lights are deployed throughout a complex.

Enterprise Security Systems

For enterprise security installations, the HC-79's compatibility with standard 12v or 24v DC systems facilitates integration with existing security infrastructure. The unit's specified service life of over 1000 hours under continuous operation with standard power supply provides assurance of reliable performance during extended operation periods, reducing maintenance concerns in critical security applications.

Product Variants and Selection Guidance

The HC-79 warning light is available in different configurations to match specific installation requirements. Understanding these variants helps ensure selection of the appropriate model for each application scenario.

Voltage Configuration Options

Three specification variants are available: flashing light for 12v systems, flashing light for 24v systems, and sound and light integrated for 12v systems. The 24v flashing light variant provides the higher voltage option for installations requiring this specification, while the 12v integrated model combines both audible and visual alerts in a single unit for standard voltage applications.

Colour Selection Considerations

Available in red, yellow, blue, and green colour options, the HC-79 allows customisation based on organisational standards or specific warning purposes. Red typically indicates highest priority alerts like fire emergencies, while other colours might denote different alert types or zones within a facility. The colour options provide visual differentiation when multiple warning lights serve different purposes within the same environment.
