The SCU (Security Control Unit) families of modular, stand-alone controllers, are basic building blocks of the TAC I/NET Seven Security Management System, and provide a flexible mix of door control and alarm monitoring features.
Three versions of the SCU are available. The SCU1284 is a door controller for up to 4 doors, with 12 supervised inputs and 8 Form C relay outputs. The SCU1280 is an input output controller with 12 supervised inputs and 8 Form C relay outputs. The SCU1200 is an input controller with 12 supervised inputs.
All SCUs function as either a stand-alone device or as part of a larger local area network (LAN) host system. By processing input data with programmed information, the SCU can control access into and exit from an area. It can monitor the status of locks and doors and a wide variety of other security input devices such as Passive Infrared detectors. The control unit in conjunction with a site controller can provide full entry and exit Anti-Passback control and complex sequence control. Alarms and events are protected against power failure and can be routed to selected building energy management system TAC I/NET Seven clients and printers, and generate fault messages according to its programming.
