2.2.3. Connect with Out-door Switch, Door Magnetism, Doorbell and Warner
Door switch is installed in the room, and you can open the door when the out-door
switch is closed. The door magnetism is used to induce the opening and closing state
of the door, and FingerKey can detect the state when the door is opened illegally and
hence output the alarming signal. Furthermore, FingerKey will also output the alert
signal if the door is not closed well within the specified time.
Alarming output of FingerKey is a switch signal, and can be connected in series into
the power loop of Warner. Of course it can be used as the trigger signal of advanced
alarming/monitoring system.
Doorbell terminal of FingerKey is connected directly with the doorbell button of
panel, so what you need to do is to connect the existing doorbell switch to these two
terminals.
