It can be easily seen that there are still some rooms for the adaptor’s supply capability.
However, it is strongly recommended to use other supplies to power heavy loads such
as door locks, alarms and so on. Also, if possible, keep these heavy loads electrically
isolated from the terminal. Electronic equipments such as the terminal tend to be
upset by surges from surrounding “noisy” devices.
