The latch input and outputs connect directly to an on-board microprocessor (uC). There is one input to specify lock/unlock (2). This is internally pulled up. When it is connected to VCC (1) or left unconnected the latch will be locked. The latch will unlock when lock/unlock (2) is pulled low (connected to ground) for longer than 10ms.
There are three outputs that indicate the status of the latch. The presence of a latch is indicated by a low signal on the latch present output (3).
The locked status (4) indicates whether the latch is in the locked position (high) or not (low). When this output is high the latch internally is in the locked state. If the door is still open, it will be locked shut when it is next closed.
The latched status (5) indicates whether the striker bolt is latched into the lock (high) or not (low). This identifies whether the door is shut and locked or not. If the latch is unlocked (see above), the latched indicator will always be low.
