FAQ
What type of sensor technology does the Bosch DS794Z use?
The DS794Z uses a passive infrared (PIR) sensor to detect occupancy by sensing changes in infrared radiation emitted by moving objects. This technology is widely trusted for its reliability in distinguishing between environmental temperature shifts and actual human or animal movement.
What is the input voltage requirement for this motion sensor?
The sensor requires a 15V DC power input, which is standard for many commercial security and building automation systems. This voltage ensures stable operation and compatibility with centralized power supplies or control panels in integrated installations.
How compact is the DS794Z, and where can it be installed?
The sensor measures 2.13 inches in height, 0.58 inches in width, and 0.33 inches in depth, making it exceptionally slim for discreet placement. It is designed for installation in ceilings, walls, or corners in offices, retail spaces, or corridors where a low-profile appearance is important.
What are the field-replaceable optics, and why are they beneficial?
Field-replaceable optics allow the sensor's lens and detection components to be swapped out on-site without replacing the entire unit. This feature reduces maintenance downtime and long-term costs, as installers can quickly service the sensor if optics become damaged or require cleaning.
How many coverage patterns does this sensor support?
The DS794Z offers three predefined coverage patterns, enabling installers to select the optimal detection zone for specific room layouts. This flexibility helps tailor motion sensing to environments like hallways, open-plan areas, or confined spaces, improving accuracy and reducing blind spots.
What is Motion Analyzer II processing, and how does it improve performance?
Motion Analyzer II is Bosch's advanced signal processing technology that analyzes PIR data to minimize false triggers from sources like airflow, sunlight, or small animals. It enhances detection reliability by distinguishing between nuisance events and genuine occupancy, ensuring more accurate system responses.
