4 (GND)
Black
Ground wire, connected to input 1 (SOS button)
5 (Input 2)
White and
brown

Connect to an external relay to remotely cut off the vehicle fuel cable or
engine power supply.
11 (Output 2)
Yellow and
brown
Output 2
Valid: low level (0 V)
Invalid: open collector
Maximum voltage for output open collector (invalid): 40 V
Maximum current for output low voltage (valid): 400 mA

engine power supply.
12 (1-Wire)
Green
TTL3.3V level
Connect to the A52 digital temperature sensor or iButton by default by
using the A61 sensor box.
Note: The DC or AC voltage that is greater than 3.3 V is not allowed.
Otherwise, the device may be damaged.
