Bosch RF940U Installation Instructions

1.0 Description
The RF940U is a high performance Wireless 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 RF940U does not detect a dog up to 13.6 kg (30 lbs.), two cats, or numerous rodents.
