Step 10: Alarm input and output cable
A: Sensor input alarm cable
Connect the external sensor to set with alarm feature to 8 external alarm input ports of the I/O sensor on the
rear panel of the MDVR. The external alarm inputs shall be connected to related sensor switching units, such as
door magnet power, emergency switch, turn signal switch and brake light, as shown in the following figure.
For example: the following block diagram shows that high level is detected when the brake pad is
stepped down; otherwise, low level will be detected. Thus, braking operation may trigger device alarm.
B: Over-speed alarm cable
