Similarly to the Integrated Management System, the system is built of appropriate communication and intercom buses, local controllers, and then executive modules (if needed) as well as locks and talking panels and other equipment.
Depending on the requirements of the user, the power supply of the system can be local or central. The system controllers are installed in a modular manner in OB-SZxx covers, and all the local node devices in practical electrical switchboards. If the switchgears cannot be used, OB-MTxx or OB-TW3M covers should be used.
