Adapting To Exiting Vehicle Detection System - Panasonic Attune WX-C3010 Installation Instructions Manual

10. ADAPTING TO EXITING VEHICLE DETECTION SYSTEM

For stores that have existing drive-thru, determine if the vehicle detection system currently in use is compatible with the
Panasonic Wireless Communication System. There are numerous types of vehicle detection systems:
PERFORMED LOOP COIL
The performed loop coil offers the most reliable vehicle detection. It will not be visible since it is almost always installed
at the time the drive-thru area is poured with concrete or paved. With the vehicle detector connected to this loop coil, the
detector LED lights when a vehicle is at the menuboard/speaker post and extinguishes when the vehicle leaves. This
PVC encased coil is almost always compatible with the Detector System Model 917-1S Vehicle Detector with
Panasonic Wireless Communication System.
SAW CUT LOOP COIL
This type of vehicle detection method is the second most and is normally installed in existing concrete or asphalt drives.
An approximate 18" x 54" saw cut on the concrete or pavement is usually visible. With the vehicle detector connected
to this loop coil, the detector LED lights when a vehicle is at the menuboard/speaker post and extinguishes when the
vehicle leaves. This coil is almost always compatible with the Detector System. Model 917-1S Vehicle Detector with
Panasonic Wireless Communication System.
SONAR
Although the Panasonic system is compatible with these units, it is preferred to use a loop coil for more reliable
performance, it is a motion sensor device that is mounted outdoors and above ground. The movement of a vehicle in the
proximity of the menuboard/speaker post triggers this device. This unit is subject to false triggering by large animals,
people and other objects. Most sonar units have a relay with normally open (N/O) dry contacts that close when a vehicle
is at the menuboard/speaker post. The relay contact opens as the drives away.
PHOTOELECTRIC
The Panasonic Wireless Communication System is compatible with this unit with a special relay module. However, a
loop coil will provide superior service and reliability. A photoelectric unit is a device that optically determines if a vehicle
is present at the menuboard/speaker post. Usually a relay is provided in these units that offers a N/O dry contact that
closes and stays closed when a vehicle approaches the menuboard/speaker post. The relay contact opens when the
vehicle drivers away.
Note: 1
The Panasonic Wireless Communication System is compatible with any vehicle detection system that provides relay
containing N/O dry contacts that close with vehicle presence at menuboard/speaker post and stays closed unit vehicle
levels. Dry contacts no voltage!
Note: 2
Before connecting any relay contact output to the Panasonic Center Module, use a voltmeter to confirm that no voltage
exists on those contacts.
Note: 3
Any type of motion sensor is prone to false triggering due to weather, animals, people, etc.
Note: 4
Some old vehicle detection systems have a relay that would close when a vehicle approached the menuboad/speaker
post, but would then open seconds later while the vehicle was still present. This type of vehicle detection is not
compatible with the Panasonic Wireless Communication System.
