RISCO WatchIN Grade 3 Dual Tech Internal Security Detector.
RISCO WatchIN Grade 3 Dual Tech — RISCO WatchIN Grade 3 Dual Tech indoor detector is designed for challenging internal environments such as production facilities, warehouses, construction sites, shopping malls, and aircraft hangars.
It combines dual microwave and passive infrared sensors to achieve accurate detection over a 25-metre wide-angle area. The detector includes advanced technology such as Anti-Cloak, which enhances detection of obscured intruders, and Sway Recognition, which prevents false alarms caused by repetitive, stationary movements like machinery or blinds.
Installation flexibility is enhanced through relay and BUS connectivity options, simplifying cabling and enabling remote diagnostics and parameter adjustments. The detector offers high resilience to interference, featuring active infrared for anti-mask detection, RF immunity up to 40V/m across 10MHz to 1GHz frequencies, and optical shielding against false alarms from direct light sources such as vehicle headlights and reflective surfaces.
Built to withstand harsh conditions, the detector has an IP65-rated housing with a rubber seal to protect against dust and humidity. It operates reliably in temperatures ranging from -30°C to +60°C, making it suitable for various indoor industrial environments. An anti-collision microwave feature also permits installation in back-to-back or face-to-face configurations without interference.

Technical specifications include voltage requirements from 9-16 VDC, with power consumption varying between 30mA to 60mA depending on operating mode and LED usage. Alarm contacts support 30VDC at 1A, and anti-mask contacts are rated at 24VDC, 0.1A. The unit measures 215 x 95 x 85 mm and weighs 0.632 kg.
