Description
BOSCH SECURITY SYSTEMS | DS9370 360° Ceiling-Mount Motion Detector, White
Panoramic TriTech PIR and 10.525 GHz microwave detection with fully adjustable optics and First Step Processing.
Reliable 360° Motion Detection for Commercial Interiors
The Bosch Security Systems DS9370 Motion Detector is a white, ceiling-mounted panoramic intrusion detector that combines passive infrared detection with 10.525 GHz microwave Doppler radar. This TriTech design requires both sensing technologies to confirm motion before activating the alarm relay, providing dependable detection while helping reduce false alarms caused by environmental disturbances.
Designed for commercial buildings and large interior spaces, the Bosch DS9370 delivers 360-degree ceiling-mount motion detection from three independently adjustable PIR sections. Installers can customize the detection pattern to accommodate the room layout, mounting height and areas requiring focused protection.
The detector incorporates Bosch First Step Processing, or FSP, for a rapid response to human movement without sacrificing false-alarm immunity. A hinged chassis, separate base plate and high-efficiency LED light-pipe system simplify installation, setup and walk testing.

Bosch TriTech Detection Technology
The DS9370 evaluates passive infrared and microwave signals independently. Both technologies must agree that valid motion is present before the detector activates its alarm relay. This dual-technology approach provides strong catch performance while helping prevent nuisance alarms caused by conditions that affect only one sensing technology.
Microwave noise-adaptive processing automatically adjusts to background disturbances, while dynamic temperature compensation helps maintain PIR performance as room temperatures change. Microwave supervision provides continued single-technology PIR coverage if the microwave subsystem experiences a failure.
First Step Processing for Fast, Reliable Response
Bosch First Step Processing analyzes signal amplitude, polarity, slope and timing to distinguish human movement from non-alarm disturbances. This allows the DS9370 ceiling motion detector to respond quickly when a person enters the protected area while maintaining resistance to common sources of false alarms. No separate installer sensitivity setting is required for FSP operation.
Installer-Friendly Design and Adjustable Coverage
The Bosch DS9370 features a hinged chassis and base plate that provide convenient access to the wiring terminals and configuration controls. Its high-efficiency LED and light-pipe system makes detector status easy to see from below during walk testing.
Three separate PIR optical sections can be adjusted vertically to customize coverage for the protected space. The supplied masking options can be used to block unwanted detection areas when full panoramic coverage is not required.
- Select a stable, vibration-free mounting surface.
- Position the detector where an intruder is likely to move across the coverage pattern.
- Avoid direct sunlight, rapidly changing heat sources and rotating equipment such as fans.
- Keep the detector away from fluorescent lighting and other potential sources of interference.
- Remember that microwave energy can pass through glass and many nonmetallic walls.
- Complete a thorough walk test after adjusting the optics and coverage pattern.

Frequently Asked Questions
Is the Bosch DS9370 a PIR or microwave motion detector?
The DS9370 is a TriTech detector that combines passive infrared sensing with 10.525 GHz microwave Doppler radar. Both technologies analyze motion to help confirm a valid alarm condition.
Does the DS9370 provide complete 360-degree coverage?
Yes. The detector provides panoramic 360° coverage using three independently adjustable PIR optical sections. Coverage can also be customized or masked for a particular room layout.
What is Bosch First Step Processing?
First Step Processing evaluates several characteristics of the PIR signal to provide a rapid response to human movement while helping reject non-alarm disturbances.
Can the Bosch DS9370 be installed outdoors?
No. The DS9370 is intended for indoor ceiling-mount intrusion-detection applications.
How is the coverage pattern adjusted?
The detector has three PIR optical sections that can be adjusted independently. Installers can aim the sections for the room configuration and use masking to exclude areas where detection is not wanted.
