Under impulse input method, for each detection of dry contact from disconnected
to connected (connected time should be more than 500ms), it is deemed as valid
impulse input. When valid impulse input is detected, dry contact gateway updates
corresponding input commands. The detail commands are shown as Table 4.2. For
each detection of valid impulse input, commands of all the dry contacts will be
re-executed. When dry contact gateway is energized, it needs about 6 seconds to
acquire operating status of unit, during such period, all the inputs are invalid.
