Automatic signal wiring
?
Fire damper: connected to 7#, 8# (connected to normally closed);
Remote control: connect 7#, 9# (start when connected, stop when disconnected)
Fire center control: connect to 10#, 11# (DC24V has no positive or negative distinction)
Forced start control: connect 12#, 13# (DC24V has no positive or negative distinction);
Passive forced start: connect 7#, 14# (start when connected, stop when disconnected).

Function operation description
?
Power-off memory saving function
This product has a power-off memory saving function. When the power is turned on again after a power outage, it will default to the state before the power outage. For example: when it is in manual mode, the power is off, and when it is powered on, it is in manual mode.
Fault type selection
In the automatic state, press and hold the "Start" button for more than 5 seconds to switch the fault signal type of terminal 15#, which is divided into normally open type and normally closed type. The factory default is normally open type.
Protection type selection
In the automatic state, press and hold the "Stop" button for more than 5 seconds to change the fault protection type of terminal 15 to the fault alarm type. It only alarms but does not disconnect the output, and switches the fault protection type in sequence.
