How to Install Bosch DS720i Motion Sensor

• Plan your installation — Select a location that maximizes the three coverage patterns for the space and minimizes obstructions or reflective surfaces that could cause false alarms. Consider traffic flow and potential sources of interference to optimize performance.
• Prepare for installation — If wiring is required, ensure the power source is properly shut off and that you comply with local electrical codes. Confirm compatibility with your security system or control panel if the DS720i is going to be integrated into an existing setup.
• Mount the detector — Secure the DS720i to a wall or ceiling using the supplied mounting hardware. Align the device so the chosen coverage pattern aligns with the intended sensing area. Make sure the mounting surface is solid and that the device sits level to maintain consistent performance.
• Install and configure optics — If field replaceable mirrored optics are provided, install the optics corresponding to the desired coverage pattern. Ensure that the optics are seated properly and not obstructed by fixtures, furniture, or architectural features that could degrade performance.
• Integrate and test — Connect the DS720i to your security system or controller as required and perform a thorough functional test. Walk the space to verify detection across all three patterns, observe timing and sensitivity, and check for any false alarms. If anti‑masking features are present, verify their response in a controlled test while maintaining safety and compliance.
• Finalize and document — Replace any covers, restore power, and conduct a final sweep of the area to confirm complete coverage. Record the selected pattern, mounting orientation, and any configuration changes for future maintenance or adjustments.
