The dormakaba extension modules 90 30 and 90 31 can be used to extend new or existing installations to meet customer requirements, without complex cabling. Extension modules are used when more inputs or relay outputs are required than are available in the access control system. The system is extended by simply plugging the modules into the control unit. This increases the number of inputs for access points or the number of relay outputs.
Areas of application:
The access manager manages and controls several doors. It can activate alarm systems, record sabotage attempts and break-ins, forward this information and send a signal.
