Be applied to building talkbacks and kinds of access controllers,especially electric locks and bolts.Through the signal lines or access controller and the other switches signal output to control the electric lock directly.Can be decrease the access controller load and reduce potential safety hazard.
Can meet various normal open( NO) or closed (NC) of electricity lock,set to unlock time delay circuit,set open button input,can open electric lock,set control points.
This 12V electric signal input control the open and close,set up automatic protection circuit inside the circuit.When an external circuit shirt-circuited,load and high temperature and high voltage occurs,will automatically cut signal output.When trouble shooting,signal output automatic recovery.Such as fuses damaged,replace the fuse.
