SOC-24VN | Hochiki's UL Approved Fire Detection

Photoelectric Smoke Detector | UL Conventional Fire Detection

SOC-24VN Description 


SOC-24VN is a reliable, high-quality Photoelectric Smoke Detector. It can be used in all open areas where Photoelectric Smoke Detectors are required, including in-duct applications. The computer-designed smoke chamber makes the SOC-24VN well suited for detecting smoldering fires as well as fast flaming fires.


NS-4 Series, NS-6 Series, HSC-4R, or HSC-R Style bases may be used with the SOC-24VN.


The SOC-24VN photoelectric smoke detector utilizes one bi-colored LED for indication of status. In a normal standby condition, the LED flashes Green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL listed sensitivity window the LED will flash Red every 3 seconds. When the detector senses smoke and go into alarm the status LED will latch on Red.
