MR688 Commercial Professional Version

Anti fatigue monitor MR688 commercial professional version is a driver safety system we specially design for companies or organizations who own commercial fleets. With its integration with fleets' AVL systems and multi-functionalities, it enables the companies or organizations to realize a highly effective fleet management and has become our best selling product.

Apart from the drowsiness and distraction alerts, MR688 at the same time delivers "No portrait" alarm to the fleet management center when the driver or operator is asleep, leaving the seat or not using the device. A vibration cushion can be connected with MR688 to make double warnings. Another accessory "hand setting instrument" supports to flexibly set a limited speed alarm. 

With years of research and development, fatigue alert system MR688 has been improved to satisfy the requirements of our customers in different regions and received wide popularity among the global auto safety market.

Constituent Parts

DIP switch setting

1. Sensitivity setting:

At the first experiences and tests on the driver sleep monitor MR688, some may wish to immediately receive alert once their eyes close, which would prove to them the system has a high sensitivity. In fact, after using for a certain time, this may interrupt them because some are non-sleeping warnings caused by unintended blinks or fake sleep, and they prefer an alarm only for real sleepy condition. So we set up 2 sensitivity levels for customers to adjust conveniently as per their requirements. For each level the driver safety monitor MR688 can quickly and accurately detect the real drowsy and absentminded conditions. The only difference lies in the alert response time.

Please see above pictures, the toggle switch is located at the back side of the product. It will be pushed to the OFF position before delivery.

1A: DIP1=OFF(Pull down), for testing sensitivity(high sensitivity, for test use), it takes about 2-3seconds to alarm when detecting the driver's sleep or distraction.

1B: DIP1=ON(pull up), for normal sensitivity, it takes a little bit more time to make an alarm when driver's drowsiness or inattention occur, about 4-5 seconds.

2.Volume setting:

According to different requirements of the operators, the volume can be set by adjusting the DIP switch 4(DIP-4)

4A: DIP4=OFF(pull down), high volume.

4B: DIP4=ON(pull up), low volume.

3.Fatigue Alarming Speed Setting:

DIP2 and DIP3 switches, for fatigue alarming speed setting (when vehicle speed is lower than warning speed, no alarm; when parking, reversing, low speed inspecting etc, automatic no alarm.)

DIP2=OFF (pull down), DIP3=OFF (pull down), any speed will alarm.

DIP2=OFF(pull down), DIP3=ON (pull up), alarm when more than 20KM/H.

DIP2=ON (pull up), DIP3=OFF (pull down), alarm when more than 30KM/H.

DIP2=ON (pull up), DIP3=ON (pull up), alarm when more than 45KM/H.

Vibration Cushion:

Fatigue sensor can connect with the vibration cushion. When the MR688 sensor detect the driver is drowsy or looking around, it will vibrate to warn the driver to keep attention to the road. Following picture will show the connection:
