Found a box of unused obsolete stock during a company clearance. The stock is obsolete but brand new in a sense it has never been used so could be quite valuable to someone in need of replacements which will save them the cost of a full system upgrade. Optex Sequad SQ-40 Wired Sequential Confirmation Detector. 2 detectors built into one saving time & money where 2 sensors need to be installed into an area possibly for police response. One detector views down the sides at 90 degrees angle & the other detector views the central area.
