Description
Bosch DS9370 TriTech 360° Ceiling Mount Motion Detector
The Bosch DS9370 is a professional 360-degree ceiling-mount motion detector designed for commercial intrusion detection applications. Its TriTech detection technology combines passive infrared sensing with microwave Doppler detection to help provide dependable motion detection while reducing unwanted alarms.
Designed for centrally mounted coverage in open interior spaces, the DS9370 provides up to approximately 46 ft diameter 360° coverage in supported applications and can be mounted at heights from approximately 8 to 20 ft. Adjustable PIR sections and included masking options allow installers to tailor the detection pattern to the protected area.
What Is the Bosch DS9370?
The Bosch DS9370 is a 360° ceiling-mounted TriTech intrusion detector that combines passive infrared and microwave motion detection. It is intended for indoor commercial spaces where wide panoramic coverage from a central ceiling location is preferred over directional wall-mounted detection.

TriTech Motion Detection
The Bosch DS9370 uses both passive infrared and microwave detection. TriTech processing evaluates information from multiple sensing technologies before generating an alarm condition, helping improve detection reliability in demanding commercial environments.
The detector also incorporates Bosch First Step Processing and adjustable detection characteristics to support professional intrusion system design.

Bosch DS9370 Coverage Area
The DS9370 provides panoramic 360-degree detection from a ceiling-mounted position. For UL and ULC applications, Bosch specifies coverage of up to approximately 23 ft radius or 46 ft diameter when installed within the supported mounting-height range.
Actual coverage depends on mounting height, PIR adjustment, room conditions, and reflective materials within the microwave detection area. The detector's adjustable optical sections allow installers to tailor the detection pattern for the space.
Adjustable Coverage and Pattern Masking
Bosch provides masking options that allow installers to block portions of the detection pattern where motion should not be monitored. The supplied masking components can be used to create partial coverage patterns while retaining the advantages of ceiling-mounted detection.
This can be useful in open commercial spaces where walls, doorways, machinery, shelving, or other areas should be excluded from the active motion-detection zone.
Common Applications
- Commercial offices
- Retail spaces
- Warehouses
- Open interior areas
- Schools and institutional buildings
- Healthcare facilities
- Lobbies and common areas
- Professional intrusion alarm systems
When to Choose the Bosch DS9370
The DS9370 is well suited for projects that require broad 360-degree detection from a central ceiling location. This design can be especially useful in open areas where a wall-mounted detector would provide only directional coverage.
For retrofit installations, verify the existing detector model, wiring, mounting location, power requirements, alarm-system design, and project specifications before ordering a replacement.
