Key Features
  • Direct-reflection infrared detection without a separate reflector
  • Detects movement and motionless objects within the 1 m sensing distance
  • Dry-contact relay output for connection to compatible alarm panels
  • Single-ended wiring, avoiding the need to run cable to a separate receiver
  • Compact design for unobtrusive indoor security installation
  • Sensitivity adjustment and visible alarm indication LED
  • Low-voltage hardwired operation
Professional Installation Requirements
  • Installation should be performed by a qualified security technician. Connect the low-voltage supply and relay output in accordance with the alarm panel manufacturer's wiring requirements and applicable electrical installation rules.
Applications
  • Indoor intruder alarm systems
  • Doorway, corridor and stairway presence detection
  • Unobtrusive security monitoring across short distances
  • Connection to alarm panels, access-control systems or other compatible dry-contact inputs
Standards & Compliance
  • AS/NZS 2201.1:2007 — relevant to the design, installation, commissioning and maintenance of intruder alarm systems; product-specific compliance was not stated in the manufacturer's documentation. ([inus04aapb1h3nprod.dxcloud.episerver.net](https://inus04aapb1h3nprod.dxcloud.episerver.net/en-au/standards/as-nzs-2201-5-2008-117333_saig_as_as_245551/?utm_source=openai))
Environmental Benefits
  • Low-current 10.5–22 V DC operation may reduce energy consumption in continuously powered security installations.
  • Compact resin construction uses a relatively small material volume and supports unobtrusive, long-term installation.
  • Ness publishes a RoHS certificate for its product range; product-specific RoHS status should be confirmed where required. ([ness.com.au](https://ness.com.au/compliance))
