how to install Bosch DS794Z Motion Sensor

Installing the DS794Z Motion Sensor begins with planning the placement to achieve optimal coverage while minimizing false triggers. Start by selecting a mounting location that provides a clear line of sight to the areas you want protected, avoiding direct exposure to heat sources, air drafts, or large metal surfaces that could affect detection accuracy. The DS794Z is designed for both surface and corner mounting, so you can adapt the installation to the room’s geometry and architectural features.

Next, choose the appropriate optics pattern. The field replaceable mirrored optics give you three coverage patterns, enabling you to tailor the detector footprint to the room layout. Install the optics that align with your desired coverage zones, ensuring that thresholds, corners, and entry points are properly encompassed. Secure the optics firmly to maintain alignment, and verify that there are no obstructions in the detector’s field of view.

Connect the DS794Z to your security control panel or system gateway following the manufacturer’s wiring diagram. Ensure the device is powered, and confirm that the detector is communicating correctly with the control panel. After wiring, mount the sensor in its final position and tighten mounting screws to prevent movement that could affect coverage.

With the detector in place and optics configured, perform the Motion Monitor test to verify coverage integrity. Use the test features to simulate movement across the target zones and observe the detector’s responses on the control panel. If any blind spots are detected, adjust the sensor angle or reposition the unit as needed to ensure full coverage. Re-check after adjustments to confirm consistent operation across all three optics patterns.

Finally, document the installation, including the chosen optics pattern, mounting method (surface or corner), and any test results. Regular maintenance should include periodic Motion Monitor testing and optical checks to sustain peak performance. The DS794Z is designed for easy field maintenance, allowing you to swap optics and perform diagnostics without removing the entire unit from its mounting plate.
