Abstract:
1. An interface for connecting a fire alarm panel to an elevator controller, comprising: an interface coupled to a fire alarm panel and an elevator controller, the interface having an action relay and a bypass relay; the action relay configured to transmit a signal to the elevator controller in response to a signal from the fire alarm panel; and the bypass relay configured for selective electrical coupling between the action relay and the elevator controller; wherein the interface has a normal operating configuration and a bypass configuration, wherein in the normal operating condition the action relay is capable of transmitting a signal to the elevator controller in response to a signal from the fire alarm panel, and wherein in the bypass configuration the bypass relay is electrically coupled between the action relay and the elevator controller such that signals from the action relay are transmitted to the bypass relay and are not transmitted to the elevator controller.
