Overview

The Orisec 200 Series Anti-Masking Detectors are developed for high security intruder detection applications where enhanced tamper protection and dependable detection performance are essential. This Grade 3 wired detector range is designed to deliver stable operation, reliable movement analysis and resistance against masking attempts in professional alarm systems.

The series includes IR-200-AM and DT-200-AM. Both models offer Grade 3 classification, Active IR anti-masking, triple or dual EOL support, selectable built-in EOL resistors, 15 metre detection range, multi height optics, 1.8m to 3.1m mounting height, interchangeable cartridges, slide to fit front cover, remote LED control, sealed optics, true creep zones, digital pulse count, temperature compensation, digital signal processing and RFI immunity up to 2.7GHz. The DT-200-AM version additionally combines PIR sensing with 24GHz microwave technology for dual technology confirmation.
