Expert answer:
Hello, in the function of MC-5800 series access control board, there is a set of alarm host functions, which can be connected to one set of alarm signal input and one set of alarm output. Support password arming and disarming or reading card arming and disarming. And if you don’t want to use the alarm host function of the access control, you can output signals to the anti-theft alarm host through the NO and COM of the police relay. When there is an access control alarm, the access control will output a switch signal to the anti-theft alarm host.
