JET, DDS latest controller, has been developed to provide a high performance on-line access control and alarm monitoring solution for large installations in terms of number of cardholders and events in memory.
The JET is a 4-reader controller supervising the entries and exits at 2 doors or the entries at 4 doors.
High capacities are reached according to the ROM and the dynamic allocation of the RAM between card holders and events buffer. This allows getting maximal capacities of 44,500 card holders (expandable to 163.000 cardholders with 2M of memory) and, depending on its configuration, it can store up to 47,000 events (expandable to 201.000 cardholders with 2M of memory).
The controller's 8I/4O (all inputs are supervised 4 states) can be extended to 16I/64O, with the addition of a plug in extension boards and three satellites. In addition there are three technical alarms for tamper, power supply failure and battery low.
Boosted system security is achieved through communication encryption and reinforced protection against lightning and short cut.
Communication channels are multiple:
The high speed CPU deals with all access control and alarm management tasks in high security installations that require very large databases. An optional 32 bits CPU can be installed to improve the controller speed.
