Abstract: A system and method for logically disconnecting fire alarm equipment from elevator control equipment to enable independent testing of each equipment set. The system and method may include an interface having a fire alarm equipment side and an elevator control side which are interconnected by a plurality of relays. A plurality of action relays may be associated with specific functions of the elevator controller. A plurality of bypass relays are interposed between the action relays and the elevator controller so that when a “bypass” operation is initiated, the bypass relays prevent signals from the action relays from reaching the elevator controller. As such, the action relays can be tested without impacting ongoing elevator operations. In addition, the logical disconnection arrangement ensures proper functioning of the system once testing is completed.
