Cebek AL-9 module is an alarm specially design for use in a motorbike. When the PCB mounted sensor of the module detects a movement, the output is automatically activated for 29 seconds. After this time the output is deactivated and the circuit will remain in quiescent mode until the sensor detects another movement. To stop the alarm once activated you have to disconnect the module from the supply. It has a relay output allowing you to connect a klaxon or siren, this can be continuous or intermittent in operation.
