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 vehicles.
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 durable 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).
Working Voltage: DC12V/DC24V
Frequency Range: 180Hz–500Hz
Rated Impedance: 8Ω (siren), 16Ω (speaker, two in parallel)
Operating Temperature: -40°C to 55°C
Dimensions: 147×120×42 mm (siren), 185×140 mm (speaker)
