Bosch DS940Q Installation Instructions

1.0 Description
The DS940Q is a high performance Passive Infrared (PIR) Motion Detector which uses advanced signal processing to provide outstanding
catch performance and unsurpassed false alarm immunity. It is designed to detect movement in the interior of a structure by sensing the
Infrared energy emitted from the human body as it moves across the detector's field of view. When motion is detected, the detector sends an
alarm signal to the Control Panel.
