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.
Vimpex has incorporated a number of innovative lens and LED light technologies into the VAD23 Range that maximises light output for minimum current. With models that combine both a traditional electronic sounder or a voice sounder with a low current EN 54-23 rated VAD, the VAD23 is truly the most versatile family of visual alarm devices currently available - providing flexible solutions for the designer and end-user.
