The HIKVISION DS-PS102X/BLUE AxPro is a wired signal generator for professional security alarm systems. This device produces a powerful acoustic alarm signal of 105 dB to warn residents and deter intruders in residential, commercial, and industrial environments. It operates on a 12V DC power supply with a current consumption of 30 mA in standby mode and 150 mA during alarm activation. The signal generator features a robust ABS plastic housing with an IP65 protection rating, allowing for use both indoors and outdoors under various environmental conditions. Its compact dimensions are 140 mm in diameter and 60 mm in depth, with a weight of 450 g for easy installation. The product includes a blue LED indicator for visual status confirmation and supports multiple alarm patterns, including continuous, interval, and temporary three-tone signals. The connection is made via a 1 m long cable with screw terminals for reliable wiring integration. The signal generator is compatible with most Hikvision and third-party security controllers that provide standard alarm outputs. This successor model of earlier Hikvision signal generators offers improved sound pressure distribution and reduced power consumption while maintaining backward compatibility with existing installations. The device undergoes rigorous electromagnetic compatibility testing and operates effectively in temperature ranges from -25 °C to +55 °C. Installation requires basic electrical knowledge and suitable mounting materials, which are not included. The product serves as an essential acoustic notification component in comprehensive security systems, where visual monitoring is complemented by acoustic alerts.
