The StarNet access control unit can be used to manage from 2-32 doors up to several thousand. The system is based on a central backplane with rapid installation KRONE connectors to interface all of the associated door wiring for an access control system and also to interface any alarm inputs or control outputs associated with an integrated system. Power connections for door locks are made using heavy duty terminal blocks thereby allowing suitable gauge cabling to be utilised.
The StarNet backplane is housed in a lockable metal enclosure and the Backplane features a tamper switch. Each backplane can accommodate 2 to 4 processor cards with the first slot containing card guides for the Access Control Processor (ACP II) which provides for:
256,000 access control cards
128,000 locally time stamped events
4,096 access permissions
Up to 32 doors per controller
Up to 15 TDEM II or IOM II plug-in modules
Up to 31 LEDA satellite modules
Available IEC 61131-3 compliant logic package
Other plug-in modules
TDEM II: two door expansion units with entry/exit readers, fall-back mode intelligence, airlock/turnstile support and multiple reader technology
IOM II: compact alarm interface units with 24 supervised alarm inputs and 8 relay outputs
LEDA 8/8: compact alarm interface unit with up to 24 supervised inputs, supports the CAN protocol and distributed PIDS applications
LEDA 8/3: compact alarm interface unit with 8 physical supervised alarm inputs, 3 relay outputs, supports the CAN protocol
Communications across the StarNet backplane make use of the CAN Bus network running at 125 Kbits / second. Up to 8 two-way Backplane units or up to 4 four-way Backplane units can be connected together provided that the total network distance is less than 400m.
StarWatch Software Management
Central to the suite of StarNet products is the 2 or 4 way Backplane unit. This is a motherboard that allows various modules from the range to interface to the StarWatch master station software.
