NEXT DUO is a digital microprocessor controlled microwave infrared detector. It uses a special columnar lens, its infrared detection stable sensitivity range is 0.5 meters to a maximum of 12 meters. The detector uses patented True Motion Recognition™ algorithm, which makes NEXT DUO can accurately distinguish between real alarm events and other false alarms.
The NEXT DUO is a digital microwave‑infrared detector that uses a micro‑processor to combine infrared and microwave sensing for reliable intrusion detection. It offers selectable detection ranges (6, 9, 12 m) and a patented True Motion Recognition algorithm to reduce false alarms. The unit operates on 9‑16 VDC and includes LED indicators for status and alarm conditions.
The manual provides step‑by‑step installation instructions, including mounting height (1.8‑2.4 m), wiring diagrams, pre‑heat time (60 s), and guidelines for avoiding interference from reflective surfaces. Safety notes, product limitations, and compliance information for FCC and European regulations are also included. This manual is written in Chinese.
