Features

  • On board battery backed real time clock keeps track of current date and time.
  • Clock accuracy is better than ± 1 minute per month.
  • Battery backed memory saves system setups and history data.
  • High Quality detachable input/output terminals for ease of connection. The DC390 doorcom contains a set of algorithms which can be used to implement complex control systems without the need for writing any programs. This allows the DC390 to keep running even if the network it is connected to fails. Communication to the DC390 is either via a standard RS232 link at 9600 baud or via Sphere Systems RS485 network.
  • Proximity - Weigand and Button interfaces.
  • First in - over ride of time control. This feature allows the timed doors to be activated only after an authorised card has been accepted by the system.
  • The DC390 has time clocks for the time control of doors and outputs. Public Holiday Schedules.
  • The DC390 has extensive database capabilities and all activities are logged. The last 1000 operations are stored and retrieved at five second intervals by the Facility Access program.
  • Anti - passback, Dual Card control function.
  • The DC390 implements a comprehensive alarm system.
