The LF-PE-4111 Conventional Type Photoelectric Smoke Detector uses a specialized smoke chamber design, which could sense the presence of smoke particles produced by fast combustion or slow smoldering fire. Combining fire algorithms stored on its memory with the special three part design of the smoke chamber and given the photo-sensor’s viewing angle, the detector can effectively sense both white smoke and black smoke with virtually no false alarms. A maximum of thirty smoke detectors can be installed on a single zone.
The LF-SI/SS Audible Strobes and Sirens are designed for maximum performance, reliability and cost-effectiveness. It adopts a built-in integrated circuit, a piezoelectric sounder and strobe which when combined, produces high energy conversion efficiency for effective output of light and sound while utilizing a minimum amount of power.
