Integrate third party devices such as intercom, intrusion, elevator, and fire detection with C•CURE 9000 via the Software House General Purpose Interface. The interface receives messages from any third party device and interprets them for C•CURE 9000 to understand. The messages are translated as C•CURE 9000 journal messages or as events. The General Purpose Interface has been designed to communicate with C•CURE 9000 and provide output messages to third party devices through the use of action activation.
