The CISS central unit consists of a motherboard with a CPU-module, mounted within the intended enclosure which in turn is mounted on the wall together with a power supply. The battery on the motherboard only supplies voltage to the date and time circuit (RTC). The database and application are permanently stored in a memory circuit within the CPU-module. The CPU-module can be transferred to another circuit board, which will carry over all data and configuration essentially making an exchange of faulty hardware as simple as possible.
The CISS supplies voltage connections, three separate RS485 communication channels (A, B and C) to other nodes within the system as well as a built-in RS232 channel for alarm transmitters.
Integrated within the CISS central unit is a web server exposing all functionality, this can be accessed through an Ethernet connection. No additional software is needed to configure or manage the CISS security system, all needed functionality is accessed directly through a modern web-browser. This way, configuration and management of the system can be done with all kind of platforms that can access a web page, such as PCs, laptops or tablets.
The CISS also has four digital inputs and four open collector (OC) outputs for internal use within the housing, such as short loops intended for tampering, voltage failures, circuit breaks and similar.
