Cygnus smoke detectors have optical smoke sensors. The smoke detectors are an integral part of the system, providing essential detection in and out of working hours on all types of construction projects, in particular, site accommodation units. Optical smoke detectors work using the light scatter principle. The detector activates the alarm when a preset threshold of smoke penetrates into the sensing chamber. Detectors come with an 85 decibel sounder. The CYG4L comes with a lithium battery pack.
