Security System Output Interface with Overload Detection and Protection

摘要

An output interface circuit for a security panel. The output interface circuit includes an output switch for activating one or more output devices in response to a control signal from a port controller. The output interface circuit also includes an overload detection circuit for deactivating the one or more output devices in response to determining that a magnitude of a voltage associated with the one or more output devices exceeds an overload threshold voltage. The overload detection circuit comprises a protection switch for rendering the output switch non or less conductive thereby preventing damage to the output switch and possibly deactivating the one or more output devices when the voltage associated with the one or more output devices exceeds the overload threshold voltage.
