OPTEX Launches SEQUAD Sequential Confirmation Detector

Product Profile

SEQUAD offers a completely new concept in PIR Detection:
  • Two PIR detectors inside one housing
  • Two non-overlapping coverage patterns
  • Two independent alarm outputs
  • Conforms to current regulations on sequentially confirmed activations
  • Proven PIR technology means false alarms are minimised
  • 'One unit - one cable' makes installation easy


The new SEQUAD contains two PIR detectors with two independent alarm outputs inside one housing.  Mounted in the corner of a room, one detector provides coverage along each of the two walls, generating an alarm if a door or window is opened.  Without overlap, the other covers the central area of the room providing a sequentially confirmed activation if an intruder then enters the room.

SEQUAD models available:

SQ-40  -  12m x 12m coverage
SQ-60  -  18m x 18m coverage
