Security cabinet to house the SiPass access control hardware. Designed in tandem with the hardware itself, the surface-mounted, single door enclosures ate purpose-built to provide secure housing while maximizing convenience of installation and operation. Cabinets feature multiple access points for cabling, an external LED to indicate the power status, a lockable door, an interior designed for holding Printed Circuit Boards and a finished, modern exterior. Three different sizes are available: small, medium and large. Even the smallest cabinet can house an Advanced Central Controller & Input Point Module, with plenty of space for peripherals like backup batteries and power supplies. The largest cabinet can house a combination of hardware unit types, making it ideal for large facilities with complex requirements. All cabinets are pre-assembled and shipped ready to install. Mounting points on the internal backplane and the chassis allow for quick and easy installation of PCBs and the enclosure itself.
