Sensor Designations
Above is a diagram which illustrates each sensor’s position. There are 7 sensors on each
cabinet total, separated into 3 “zones”.
The zone designated as “Sensor Zone 1” is part of the intelligence behind whether or not
authorized access has been granted. For example, if the zone 1 sensors have been tripped
but direction 2 was the direction that authorization was granted, an alarm will trigger.
The zone called Sensor Zone 2 does the same thing as zone 1, but in the opposite
direction.
The sensor zones have another function as well. On free flow mode, when the sensor
zone for the appropriate direction is actuated, access is granted for that direction.
The third zone are sensors which prevent the arms from closing on obstruction and also
serve as anti-crawl through sensors. These will detect unauthorized people who are
attempting to crawl underneath the main zones.
