Installation Instructions
1.0
Description
The DS940P is a high performance Passive Infrared (PIR) Motion Sensor 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 sensor’s field of view. When motion is detected the unit sends an alarm
signal to the Control Panel. With Bosch Security Systems Pet Friendly
®
pet immunity, the DS940P will not detect a dog up to 30 pounds (13
kilos), two cats, or numerous rodents. This pet immunity feature has not been tested by Underwriters Laboratories.
