INNE PDM-I18 Dual Technology Motion Detector (PIR + Microwave), 18m Range, EN 50131-2-4 Grade 2

The INNE PDM-I18 stands out from conventional motion detectors by combining passive infrared and microwave Doppler sensing in a single unit. This dual-technology approach virtually eliminates false alarms caused by drafts, sunlight, or small animals, while maintaining reliable catch performance for human intruders. With a wide 18 x 18 m detection pattern and adjustable pulse count, it adapts to demanding indoor security environments where dependable detection is non-negotiable.

Highlights

• Dual technology: PIR + 10.525 GHz microwave for superior false alarm immunity
• Wide-angle coverage: 18 m x 18 m, mounting height from 1.8 to 3.0 m
• EN 50131-2-4 Grade 2, Class II certified for professional installations
• Adjustable pulse count (1 or 2) to fine-tune sensitivity per zone
• NC relay alarm output rated 60 VDC / 100 mA, plus tamper protection
• Walk-test LED simplifies alignment and verification during setup

In daily use

Installers appreciate the PDM-I18's straightforward setup: a Fresnel lens with dual-element PIR and a stable microwave module work in parallel, requiring both technologies to trigger before an alarm is generated. The detector operates from 9–16 VDC and draws only 15 mA in standby, making it easy to integrate into existing control panels. Its IP30 rating suits indoor use, while the operating range of -10 °C to +55 °C covers most residential and commercial spaces. The tamper output adds a layer of security against unauthorized opening or removal.
