When “Keep Out!” isn’t enough …


“Keep out!”  Those words signposted outside your property would be enough to convince the average person to stay away.


It takes a lot more than a warning sign to keep criminals at bay, however.  With the recent release of Optex’s new range of photo beam sensors, the fight against crime has been given a major boost, says Kenny Chiu, marketing manager of Elvey Security Technologies. 


He lauds the new Optex AX-350/650TF series for a number of reasons, one being its ability to create an invisible fence around properties.  Businesses are increasingly using early detection systems to prevent criminals from accessing their properties and in so doing, compromising the safety of staff and stealing products and vehicles.  Photo beam sensors are ideally suited to perimeter protection owing to their ability to create an invisible fence and trigger an alarm in the event of a breach.”


Adds Zane Greeff, Elvey’s technical director: “The new Optex AX-350/650TF series boasts dual beam, long-range sensors with external ranges of up to 200m and internal ranges of up to 400m.  This makes them ideal for use in larger installations.  In addition, the beams offer four site-selectable frequencies that create a wall of coverage when stacked one on top of another.  I also like the fact that beam interruption time can be adjusted to fit any application.”


The AX-350/650TF series’ patented alignment technology (I.A.S.C.), allows for the transmitter to be programmed with alignment data, he notes further.  It is also responsible for the receiver’s easy ‘single-man' aiming capability, which dramatically reduces installers’ setup and alignment times. 


To further increase security, Greeff says beam height and direction can be disguised by installing them inside beam towers.  “This IP54-rated unit also boasts an improved electro-magnetic interface surge absorber and high-surge resistive relay which protect the beams from lighting and electrical surges.  Being equipped with D.Q Circuitry is another benefit since it can send trouble signals when the beam strength drops below an acceptable level.”
