When installing FlipX indoor sensors, most performance issues reported to our technical team are not related to the product itself, but to setup choices made during installation. Based on recurring questions from installers, here are the key areas to ensure detection reliability and reduce callbacks from day one.
The FlipX series offers adjustable PIR sensitivity levels to suit different environments and risk levels. Lower settings suit stable indoor spaces; higher settings are for more demanding conditions or elevated-risk applications.
On EN Grade 3 models (FLX-A-AM and FLX-A-DAM), a Super High PIR sensitivity option is also available for maximum detection performance. While not typically required, it can be beneficial in high-risk applications or challenging conditions, such as very warm environments where detection contrast may be reduced. Whichever level you select, always confirm with a walk test using real movement across the protected area before signing off the installation.
Model choice often comes down to how predictable the environment is. In stable conditions, standard PIR models deliver strong results. In areas with airflow, temperature shifts, or intermittent disturbances, dual-tech models add an extra layer of filtering. Both PIR and microwave must trigger before an alarm is raised, which helps reduce nuisance activations.
But it’s important to remember that microwave detection only works in wide detection mode. When the lens is flipped to narrow detection, the microwave function is automatically disabled. This should be considered when selecting both the model and the intended coverage pattern.
The ability to switch between wide and narrow detection is a core feature of the FlipX range, and one that directly affects performance when applied correctly. Wide detection is used for open areas requiring broad coverage, while narrow detection is intended for corridors or long, narrow spaces where focused detection is required.
The adjustment itself, rotating the lens module by 180 degrees, is simple and straightforward. However, in practice, the key point is not the adjustment, but the validation. Always walk test after changing the detection pattern to confirm coverage aligns with actual movement paths and that there are no gaps or overshoot.
Mounting height has a direct impact on detection quality. FlipX sensors perform best when mounted between 2m and 2.5m, with 2.2m as a reliable reference point. The angle also matters. A slight downward tilt, around 5- to 10-degrees, ensures detection zones intersect with the torso rather than the lower body, which improves consistency.
The Down Zone feature creates a detection area directly beneath the sensor and is enabled by default. Turn it off if masking the immediate under-zone is part of the system design or if close-range movement in that area is causing nuisance triggers. Disabling it is also a requirement for EN Grade 3 installations. Remember to keep Down Zone enabled for EN Grade-3 installations, as it is a system requirement.
Common installation mistakes to avoid
Environmental factors are the cause of many avoidable issues, for instance:
Sensors placed facing direct sunlight or large glass surfaces can suffer from infrared interference and reflections;
Units installed near HVAC vents or heaters may respond to rapid temperature changes;
Shelving, partitions, or large objects create blind spots – check for obstructions before finalising placement.
Before you finish: a quick checklist
Confirm sensitivity settings, verify detection mode, check mounting height and angle, and conduct a full walk test. Allow a short observation period to ensure stable operation with no unwanted activations. These steps add very little time on site, but they can significantly reduce callbacks and ensure the system performs as expected from day one.
