The B-I Industrial JINDOGAE-SM is a highly reliable conventional optical smoke detector designed for early fire detection in commercial and industrial environments. It operates on the principle of light scattering, allowing it to effectively identify smoke particles from smoldering fires. Featuring a non-polarized 2-wire system, installation is simplified and wiring errors are minimized. The detector includes a built-in LED indicator that provides a clear 360-degree visual confirmation of its alarm status. Constructed from durable, fire-proof ABS resin and equipped with a self-diagnosis function, the JINDOGAE-SM ensures consistent performance and long-term stability for fire alarm systems.
