4 Functions
4.1 Shield general terminals
Once the first bit of DIP switch S1 is set to Digital position (General terminals
control disable), the unit will shield the general terminals (wired controller, remote
controller, APP and light board), and high-end terminals (central controller,
long-distance monitor, keycard control) and dry contact gateway can still control the
unit. When the first bit of DIP switch S1 is set to ON position (General terminals
control enable), all the terminals can control the unit.
4.2 Input function
Dry contact gateway is compatible with level input method and impulse input
method, which can be selected by the second bit of DIP switch S1. Each input
function can be set as enable or disable through the corresponding bit of DIP switch
S2. When it is set as disable, the unit won’t execute corresponding input command.
The following descriptions of input functions are supposed as the input functions are
enabled.
4.2.1 Level input
Under level input method, the input command is decided by the
Connected/Disconnected of the dry contact. Each time when the status of dry contact
is changed, input commands of all the dry contacts will be re-executed. The
