Jablotron JA-120PB BUS wired motion/glass-break detector
The JA-120PB combines a PIR motion sensor with a dual glass-break detector, breaking a window can be detected up to 9 meters away. It uses digital signal processing to avoid false alarms. It provides an input to connect a door sensor. This detector occupies two addresses in the control panel to distinguish between motion and glass breaking.
The glass-break detector uses the analysis of air pressure variations combined with the characteristic sound of glass breaking. The product is designed for internal use in buildings.
