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 pro-vides alarm and fault outputs.


  • Two wire, polarity independent allows for easy connection
  • 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
