Optical Smoke Detector Lf-pe-4111

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 slows moldering 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. Accurate analysis of fire is achieved using it’s built in microprocessor and fire data stored in its non-volatile memory. With the detectors automatic environmental compensation settings, it would adjust itself according to its environment or application thus improving the veracity of fire judgment. Three levels of sensitivity is also provided with the detector using jumper selections. Depending on the application, the sensitivity is set by removing the PCB mounting plate and shorting the terminals to achieve the desired setting. The LF-PE-4111 Conventional Type Photoelectric Smoke Detector also has the provision of connecting a remote LED indicator. The detector’s design widely applies to all kinds of industrial and commercial constructions with its high resistance to humidity, wide operating temperature range, high reliability and ease of installation and configuration.
