Alarm in / Output Connection Mode
Among them, SENSOR-IN* is an Alarm Input Port. SENSOR-OUT is an Output Control
Port.
Alarm inputs usually use a High Level (12V) input to trigger. They can be used to
connect an SOS button and driving status connections such as: braking, turning,
opening door etc.
The following is the brake light (STOP) detection diagram. When braking, the device
can detect the high level or the low-level change of state.
The Alarm Output is a Relay Switched Output. It can connect to an Acoustic-Optic
alarm. Remote Oil/Power cut off etc. If you are switching high power then we
strongly recommend you connect an external relay.
The alarm output diagram as below:
