HC-79 24V Warning and Alarm Light: 105dB Siren with Strobe for Building Safety

The Ji'an Electronics HC-79 Warning and Alarm Light is designed to deliver reliable emergency signalling for commercial and community fire safety systems. Combining a bright, attention-grabbing strobe light with a powerful integrated siren, this unit ensures alerts are both seen and heard. Its compatibility with standard 12V and 24V DC operating voltages makes it a versatile component for integration into existing security or fire alarm panels. The compact 73mm diameter by 45mm height form factor allows for discreet yet effective placement on walls or ceilings, while the choice of four distinct LED colours enables customisation to specific safety protocols.

Features and Construction

The HC-79 model is engineered as a combined visual and auditory alert device, providing a comprehensive warning solution from a single unit. Its construction focuses on delivering clear signals with operational efficiency for continuous safety system use.

Material and Build

Housed within a durable plastic casing, the unit protects the internal LED strobe and siren components. The design centres on functional reliability for alert systems, with the electronics engineered for a long service life under standard power conditions. The construction facilitates the dual-alert function without requiring separate light and sound units, simplifying installation and wiring.

Size and Practical Fit

With dimensions of 73mm in diameter and 45mm in height, this warning light maintains a compact profile suitable for various mounting locations. The size allows it to be installed in corridors, entryways, or specific hazard zones without being obtrusive. The included mounting base and screws provide the necessary hardware for secure attachment to walls, panels, or other surfaces as part of a building's safety infrastructure.

Uses and Placement

This product serves as a critical component in environments where clear, unmistakable warnings are required. Its application spans professional safety systems and designated alert zones where both sight and sound signals are mandated or advised.

Event or Professional Use

In enterprise buildings and community fire protection systems, the HC-79 provides the visual and auditory signals needed to alert occupants during drills or actual emergencies. The high-intensity strobe, flashing at up to 120 times per minute, and the 105 decibel siren are designed to penetrate busy environments. The availability of red, yellow, blue, and green colour variants allows facilities to colour-code alerts for different types of emergencies or to comply with specific regional safety standards.

Everyday Home Use

While primarily designed for commercial and community safety applications, this unit can be integrated into comprehensive home security or fire alarm systems, particularly in larger properties or outbuildings. The low 30mA to 50mA working current makes it suitable for systems with battery backup, and the voltage compatibility allows connection to common low-voltage security panel outputs. Its robust design supports reliable operation in the event it is needed.

Benefits and Buying Value

Choosing this warning light centres on obtaining a verified, dual-function alert device with clear specifications for system planning. The value lies in its combined functionality, voltage flexibility, and the concrete performance metrics provided for integration.

Reuse and Low Maintenance

The product is designed for installation as a fixed component of a safety system. Its service life under standard continuous power is indicated, supporting its use as a long-term alert solution. The solid-state LED and siren components require no routine maintenance beyond ensuring electrical connections remain secure, contributing to a low upkeep profile once installed.

Why Choose This Product

This HC-79 model offers a practical combination of a strobe light and siren in one verified unit, eliminating the need to source and wire separate devices. The specified 105 decibel output and strobe flash rate provide measurable performance data for safety system design. The inclusion of four colour options and dual-voltage operation (12V/24V DC) provides tangible flexibility for matching existing system voltages and coding requirements, making it a versatile choice for safety upgrades or new installations.
