PIR detector CDX-NAM

for indoor usewith anti-masking function

Overview
CDX-NAM is an indoor narrow-field Grade 3 PIR motion sensor (hardwired) providing 24 x 2 m detection coverage, suitable for corridors and interior building protection. The sensor uses an 82-zone dense optical array; within the specified narrow coverage the product registers 20 primary PIR zones. The series integrates the digital MPU "CORE PLATFORM" for precise signal processing and reliable detection performance.

Key features

• 24 x 2 m indoor PIR, hardwired model
• Double conductive shielding to reduce visible-light and RFI interference
• Plug-in EOL unit (option)
• Digital QUAD-zone logic: 4 or more zones must be crossed to register human detection
• Active IR Digital Anti-Masking (AIR technology)

Anti-masking and shielding
The CDX series uses AIR technology to detect masking and to distinguish true masking from environmental changes (dust adhesion, temperature shifts, direct light) by optimising sensitivity and processing. CDX-NAM adds Double Conductive Shielding to block visible-light disturbances and RFI for stable operation in challenging indoor environments.

Applications

• Buildings and facilities
• Houses and residential corridors
• Indoor corridors and secure interior zones
