External detectors have been traditionally designed to work at a fixed range, but the D-TECT-50 can be set to operate over any distance in its range detecting movement up to a 45 meter perimeter.
Once installed at say a height of 3 metres, the D-TECT-50 can also be adjusted from the ground using a hand-held key fob, which will automatically change the range and pulse count sensitivity to the required level.
GJD's new D-TECT-50 long range perimeter detector is BS8418 compliant and comes fully loaded with complete D-TECT² functionality, offering all the following features and benefits:
• Adjustable range from 25m to 50m
• Two Fresnel lenses giving up to 50m x 5m or 50m x 10m beam coverage
• Variable mounting height up to 6m, optimum 3m
• An adjustable pan (180°) and tilt (90°) module
• Optional remote IR programmer, which is a great benefit for post installation adjustments
• Exceptional resistance to false alarms
