LIFECO LE-SPC-24 Projected Beam Smoke Detector | Emitter Unit

Protect expansive, high-ceilinged spaces with the premium LIFECO LE-SPC-24 Projected Beam Smoke Detector (Emitter Unit). Manufactured by Lichfield Fire & Safety Equipments Co. and produced in Japan, this industrial-grade optical beam smoke detector is engineered to safeguard environments where standard point detectors are impractical—such as warehouses, factories, aircraft hangars, shopping malls, and historical atriums.

This specific unit is the Emitter module, which projects a precise infrared light beam across a designated span to a corresponding receiver unit. It operates on a reliable low-voltage control loop supporting standard contact ratings of 0.5A at 24VDC. The advanced optical array features a broad obscuration sensitivity range adjustable between 25% and 70% per span, allowing it to detect stratified smoke clusters with maximum accuracy while filtering out environmental dust interference.

Built inside a durable, impact-resistant neutral housing with an integrated front infrared lens shield, the module allows fine alignment adjustment via physical alignment lenses. It supports a maximum allowable misalignment tolerance angle of $\pm$0.5°, ensuring long-term structural link stability even in active industrial buildings.
