Bosch DS9370 Motion Sensor

The Bosch DS9370 Motion Sensor is a panoramic, TriTech PIR/Microwave detector engineered to deliver exceptional motion-detection performance with minimal false alarms. Designed for ceilings up to 7.6 meters (25 feet), this sensor provides broad, uniform coverage across large spaces such as open-plan offices, retail environments, and industrial interiors while staying discreet and tamper-resistant. Its three independent PIR sections work in concert with microwave sensing to create a robust, dual-technology solution that intelligently differentiates between people and non-threatening movement. The DS9370 is built for reliability in fluctuating conditions—from busy storefronts to busy manufacturing floors—thanks to patented processing techniques that optimize catch performance and suppress nuisance triggers. Seamlessly integrating with Bosch security systems and control panels, the DS9370 offers straightforward configuration, reliable alarm reporting, and strong performance in dynamic environments, making it an excellent choice for professional installers and security-focused businesses seeking comprehensive coverage with minimal maintenance.

• Panoramic TriTech detection: The DS9370 combines passive infrared (PIR) sensors with microwave detection and advanced digital signal processing. With three independent PIR sections and a panoramic field of view, it captures movement across a wide area while prioritizing signals that indicate genuine human activity. This multi-sensor fusion enhances detection accuracy in open spaces and allows for precise discrimination between intruders and harmless motion, reducing false alarms while improving overall security coverage.
• Ceiling-mount versatility for expansive spaces: Specifically designed for ceiling installation up to 7.6 meters (25 feet), the DS9370 leverages overhead placement to minimize blind spots and maximize interior coverage. The panoramic design ensures uniform detection around the room, making it suitable for large offices, retail interiors, and industrial environments where wall-mounted sensors may leave gaps in protection. The elevated position also helps preserve interior aesthetics by keeping the sensor out of direct line of sight.
• False alarm minimization through patented processing: Bosch’s patented processing techniques analyze motion patterns, speed, direction, and sensor data to distinguish legitimate human movement from environmental noise, drafts, or background activity. This intelligent filtering reduces nuisance alarms and ensures that alerts reach security personnel promptly, improving response times while maintaining occupant comfort and workflow in busy spaces.
• Professional-grade construction and seamless integration: Built to endure demanding commercial environments, the DS9370 features a rugged housing and tamper protection to safeguard against tampering and accidental impacts. It is designed for smooth integration with Bosch security systems and control panels, enabling straightforward programming, reliable event reporting, and centralized monitoring within an existing Bosch ecosystem.
• Easy installation, testing, and ongoing maintenance: The DS9370 is designed for efficient installation, with simple mounting, zone alignment, and field testing. It offers adjustable sensitivity and an accessible test mode to verify coverage quickly. Once commissioned, maintenance remains minimal thanks to clear indicators, stable performance, and seamless integration with Bosch management tools for routine checks and firmware updates when needed.

How to install Bosch DS9370 Motion Sensor

Step 1: Plan the installation — Select a ceiling location that provides centralized, unobstructed exposure to the space. Ensure three PIR zones can cover the intended footprint and avoid placing the detector near large heat sources, air vents, or reflective surfaces that could affect sensitivity. Confirm the mounting surface is structurally capable of supporting the device and that wiring paths comply with local electrical codes.

Step 2: Gather and prepare — Power down the relevant circuits and verify compatibility with your Bosch control panel or security system. Collect all mounting hardware, connectors, and any required seals or spacers included with the DS9370. If you’re installing at height, ensure safe access with proper equipment, and have a test device available for initial verification after mounting.

Step 3: Mount the bracket and device — Secure the mounting bracket to the ceiling using appropriate fasteners for the surface. Attach the DS9370 housing to the bracket, confirming a firm, stable fit. If tamper protection is present, verify the tamper switch engages when the cover is disturbed. Route cables neatly, keeping them away from moving or heat-generating components and following local wiring practices.

Step 4: Align, configure, and test — Use the security system controller to enable the DS9370 and set the sensitivity to match the room’s activity level. Conduct a walk test or use the built-in test mode to validate detection at various distances and angles. Adjust the lens alignment or sensor orientation as needed to guarantee robust panoramic coverage and minimize blind spots.

Step 5: Commission and verify — Complete a thorough walk-through of the space to confirm the detector responds to human movement consistently. Check for nuisance triggers from HVAC activity, door movement, or fans and fine-tune sensitivity or placement to achieve a balance between high catch rate and low false alarms. Document the installation steps, panel programming, and test results for future maintenance and audits.
