The passive glass break detector, GD475, is certified to EN Grade 3 and is suitable for float, tempered, laminated & reinforced glass. The GD475 is glued to the glass surface and will detect var-ious attacks (including cutting tools) on the glass surface. The detector requires an interface unit IU400, which senses the changes in the current characteristics of the detectors and provides alarm and fault outputs.

  • Detects attacks on all types of glass
  • Detects crushing of glass
  • Detects cutting through glass with tools
  • Detection radius up to 2m
  • High resistance to interference – rain, hail, foliage, doors shutting, etc
  • No sensitivity adjustment required
  • Suitable for 24 hour surveillance
  • Low power consumption
  • DAY/NIGHT LED control
  • Embedded electronics with IP 67 rating
