EP-Ⅰ |
| Q1 |
How does the EP-I detect vehicles? |
| A1 |
Ultrasonic waves are emitted in the space between the bottom of the car and the ground, the echo from which is measured to determine whether or not the space is occupied. |
| Q2 |
Can other objects, such as empty cans, give a false reading? |
| A2 |
Objects with small echoes, objects less than one meter from the sensor, and objects that are not stationary for at least four seconds are not detected. However, an object such as a human may appear to be a parked vehicle if it remains stationary in the appropriate area for a certain amount of time. |
| Q3 |
Are sensors affected by wind or rain? |
| A3 |
If a car is present, it will act like a roof over the sensor even during a typhoon, and so it will still be properly detected. If the sensor is submerged, however, the parking space will appear to be unoccupied. As the sensor itself is splash-proof, though, it will not be damaged. If covered by snow, the snow will enter the cones and prevent the entry and exit of sound waves, causing the parking space to appear to be unoccupied. |
| Q4 |
Can sensors with stand being run over? |
| A4 |
The EP-I is coated in a tough aluminum die-cast cover that can even withstand being run over by a truck. If installed in a location where it will be frequently run over, however, it could be deformed or become loose. |
| Q5 |
Do sensors require any wiring work? |
| A5 |
The EP-I uses a unique thin four-core cable that is laid in a groove measuring approximately 4mm in width and 15mm in depth cut using a cutter used for road repair work. |
| Q6 |
Can the system be used with parking charge systems? |
| A6 |
The sensor is designed to smoothly guide drivers to parking spaces. If used in combination with “flappers” or other parking charge systems, there is the risk of sensors being jammed or otherwise vandalized.
If used outdoors, there is also a possibility that vehicles might not be detected due to cones becoming blocked.
If you intend to use Exnos sensors with a parking charge system, please give careful consideration to the sensors’ features and limitations. |

EP-II |
| Q7 |
How does the EP-II sensor differ from the EP-I? |
| A7 |
The P-I and EP-II look identical.
As they use the same sensing principle, the same environmental constraints apply to the EP-II as for the EP-I. The EP-I employs numerous sensors connected to a control board, which decides whether a vehicle is present. The EP-II, on the other hand, has its own built-in CPU that enables it to decide independently whether a vehicle is present and to output the result elsewhere. For systems of 10 parking spaces or fewer, we usually recommend the EP-II. |

EP-III |
| Q8 |
How are vehicles detected? |
| A8 |
EThe EP-III is mounted in the ceiling midway above the parking space.
By measuring the distance from the sensor to the top of the vehicle beneath, it can determine whether a vehicle is present. |
| Q9 |
Can objects other than vehicles cause false results? |
| A9 |
Any object that remains stationary for several seconds and is at least around 50cm above the ground will appear to be a parked vehicle.
If a person stands immediately beneath the sensor, he or she may be judged to be a parked vehicle.

General questions about our systems |
| Q10 |
What kinds of display equipment do you offer? |
| A10 |
With our extensive track record, we can provide displays to suit almost any kind of parking facility. We also develop our own hardware, such as large LED text panels and wheelchair symbols. We provide the system from our extensive range for parking facilities that best suits the customer’s parking facility.
|
| Q11 |
Is a personal computer required? |
| A11 |
As sensor systems can independently determine and indicate whether vehicles are present, a personal computer is not an essential requirement.
If you want to monitor use in real time on a computer screen or analyze cumulative statistics on use, it is possible to easily set up a monitoring system by hooking up each controller by LAN cable.
|
| Q12 |
How much does it cost to install? |
| A12 |
The equipment we use is not only low priced in itself, but is also cheap to install.
The overall cost will vary according to the scale of the customer’s parking facility and the type of indicator equipment used. Please send us a simple layout diagram of your requirements, and we will suggest a suitable configuration and provide an estimate free of charge.
