GF-SK02 Siren And YD-100-23 Speaker Enhance Public Safety With Low-Frequency Penetration

A new advanced alarm system comprising the GF-SK02 siren and YD-100-23 speaker has been published, offering improved society alarm capabilities through innovative low-frequency acoustic technology. Designed for emergency vehicles emergency.

The feature of the system is its powerful penetrating ability, which create a marked "low-frequency tremor" effect. This not only ensures the siren is heard but can also be physically felt, improving alert effectiveness in noisy environments, across long distances, and in complex architectural settings.

Constructed with PE injection-molded casing, the devices are both firm and aesthetically refined. Equipped with a power amplifier, the system ensures consistent and reliable sound output. It operates across a wide temperature range from -40°C to 55°C and supports dual voltage inputs (DC12V/DC24V).
