The Next Duo is a Dual Technology Digital Detector designed to prevent false alarms due to interferences in residential and light commercial environments. A passive infrared (PIR) sensor and a complementary active microwave sensor are combined in a single unit, giving Next Duo an unprecedented capacity to distinguish between the motion of a human body and any other disturbance.
The GS-133 detects all mixtures of air and combustible gas (Natural Gas, Methane, Propane, Butane, Acetylene, GPL, etc). The detector detects two levels of gas concentration - with corresponding output reactions. The main GS-133 features are: high reliability and sensitivity, compact size and long stability & lifetime.
The detector is intended to detect human body movement in buildings. Using two sensors ensures better immunity against triggering by moving pets. The signal is processed by a multiple signal analysis method which guarantees excellent sensitivity and a high resistance to false alarms. Detection analysis can be adjusted to increase its immunity (if installed in a problematic location). The detector distinguishes itself with excellent immunity against high frequency interference and other false signals. It can be installed on a flat wall or in a corner.
