Linear Selection Generator

Linear Le100 Random Selection Generator

The unit is designed to provide an efficient method of selecting any sample percentage of persons passing through a security checkpoint, but in a completely random fashion.  In any situation where physical searching of employees or even customers is necessary it is essential to avoid embarrassment or claims of victimization du to the selection process.

 

The Random Selector will overcome all these problems and select at random, whatever percentage is required by the user to be searched.  Whenever the unit is triggered a green light or red light and buzzer is activated, indicating either free passage or search. 

 

Several methods can be used to trigger the selector, for example,  push button, remote hand held transmitter infra-red beam or card reader.  The search output can be selected by jumper to provide either a timed or latched output.  If a timed output is selected by jumper to provide either a timed or latched output.  If a timed output is selected each time the unit is triggered a green light or red light and buzzer will be activated for a preset time of 1 to 99 seconds to alerts security personnel that a selection has been made. 

 

If, however, a latched search output is selected, the red light and buzzer will sound until reset at the random selector or via a remote push button.  The free passage selections will still be timed.

 

When used with a turnstile or doors fitted with electric locks the system becomes automatic, requiring a minimum of supervision.  As the system is random it is possible to have numerous selections in quick succession even at relatively slow selection percentages.  This acts as a strong psychological deterrent.
