ZDD-111PIR Features:

1. Ceiling Mount Design: Specifically designed for ceiling installation to provide a 360-degree detection coverage with a 9m diameter (29.5ft diameter).
2. Passive Infrared Technology: Utilizes quad-element PIR sensors for enhanced motion detection accuracy.
3. Adjustable Sensitivity: PIR sensitivity can be adjusted to cater to different environmental conditions and requirements.
4. 360-Degree Detection Angle: Provides complete coverage in all directions, making it ideal for open spaces and large areas.
5. Anti-masking Function: Provides protection against attempts to obscure or block the detector’s field of view.
6. Anti-blocking Function: Ensures the detector remains operational even when subjected to attempts to block its view.
7. Temperature Compensation: Automatic adjustment to account for temperature changes, reducing false alarms.
8. Multiple Alarm Output Options: Supports both NC (Normally Closed) and NO (Normally Open) outputs, offering flexibility in alarm system integration.
9. Fast Alarm Response: Alarm output is triggered within 2 seconds (default setting) of detecting motion.
10. Tamper Switch: NC tamper switch provides additional security by triggering an alarm if the detector is tampered with.
11. Wide Operating Voltage Range: Compatible with power supply voltages ranging from 9VDC to 16VDC.
12. Low Power Consumption: Consumes less than 18mA at DC 12V, ensuring energy efficiency and longer battery life.
13. Durable Construction: Housed in a robust ABS plastic enclosure with an IP40 protection rating against dust and water ingress.
14. Easy Installation: Designed for easy ceiling mounting with a compact size of 106mm x 106mm x 35mm and lightweight design (approx. 90g).
15. Certified Quality: CE and RoHS certified, ensuring compliance with international standards and regulations.
16. Versatile Applications: Suitable for use in residential homes, commercial buildings, offices, and other indoor areas requiring ceiling-mounted motion detection.
