Abstract
An interlock system for signaling a nurse call patient station is disclosed. The interlock system may include a first terminal and a second terminal. The first and second terminals may be configured to be connected to corresponding terminals of a signaling loop of a nurse call patient station. The interlock system may further include a connection circuit. The connection circuit may be configured to electrically connect the first terminal to the second terminal. The interlock system may also include a control circuit in communication with, but isolated from, the connection circuit. The control circuit may include a microcontroller. The control circuit may be isolated from the connection circuit by an isolation circuit. The control circuit may be configured to operate the connection circuit to connect or disconnect the first terminal from the second terminal.
