KNTECH Launches KNL12S Fireproof Ceiling Speaker: Combining Advanced Fire Safety, IP55 Protection, and Superior Audio Performance

Hongkong Koon Technology Limited (KNTECH) today officially announces the launch of its latest innovation, the KNL12S Fireproof Ceiling Speaker. Specifically engineered for public address systems that demand the highest levels of safety and audio intelligibility, this product features a built-in fire dome, thermal fuse, IP55-rated weatherproofing, and high-fidelity audio performance, designed to provide a reliable life-safety broadcasting solution for commercial and public spaces worldwide.

Rigorous Fire Safety to Protect Lives
In emergency situations such as fires, the reliability of a PA system is critical. The core highlight of the KNL12S lies in its design that meets strict fire safety standards. The product includes a rear fire dome and is equipped with a thermal fuse. When the ambient temperature exceeds 115°C (±5°C), the fuse automatically opens, effectively preventing fire from spreading through the speaker openings and ensuring the integrity of building fire compartments. The product complies with EN 54-16 and ISO 7240-16 standards and holds multiple international certifications including CE and IEC, making it an ideal choice for high-end commercial spaces and public facilities.

Stable Performance in Harsh Environments
Beyond fire safety, the KNL12S boasts IP55-rated waterproof and dustproof capabilities. Its metal housing is rustproof, with an operating temperature range of -20°C to 50°C and humidity tolerance of less than 95%. Whether in humid underground parking lots, dusty industrial environments, or complex outdoor shaded areas, this speaker maintains stable operation, greatly expanding its application scenarios. From home theaters, conference rooms, and tea houses to coffee shops and high-end private clubs, the KNL12S integrates seamlessly into any environment.

Professional Audio Quality and Easy Installation
The KNL12S features a 3-inch speaker driver with a wide frequency response range of 90Hz to 20kHz and a coverage angle of 120° (-6dB), delivering uniform and clear sound coverage. In 100V constant voltage mode, it offers power tap selections of 3W and 6W, with a sensitivity of 90±2dB (1W/1m) and a maximum sound pressure level of 98±2dB. Measuring Φ185*80mm and weighing only 1.55KG, it features ceiling-mounted installation with two M20 plastic cable glands for quick wiring and easy installation.

System Integration for a Complete Security Ecosystem
The KNL12S integrates seamlessly into KNTECH's Public Address System ecosystem. In typical applications, the speaker can be paired with KNTECH's Network Switch (KNPB-24), 1 IP Power Amplifier (KNPMG-600D8), and Public Address System Controller Server (KNTD-50PA), enabling fully digital, highly reliable audio transmission and emergency broadcasting from the Paging Microphone (KNPA600) to the terminal speakers.
