Entry System Door Controller for AES. Up to 32 additional points of entry may be added to Viking s model AES-2000 Accessible Entry System. One ES-3, one Wiegand device and a door strike or magnetic lock of your choice is required for each additional entry point. The ES-3 is an entry system door controller designed to operate a door strike or magnetic lock upon receiving a valid card read from a Wiegand device. The Wiegand device used may be the Viking model HID-1 Proximity Card Reader or any other card reader, RF transmitter or digital keypad that outputs the 26 bit Wiegand format. Up to 525 valid Wiegand codes can be programmed into the AES-2000, and up to 1024 access entry events are logged and stored in the AES-2000. Other programmable parameters, like relay activation and delay times, are also PC programmed via the AES-2000. Only one pair of wires are needed to wire all 32 Entry System Door Controllers back to the AES-2000. This two wire CAN communication protocol allows the ES-3 to be installed up to 1 mile away. Power to the ES-3 can also be daisy chained from unit to unit on a single pair of wires, or simply tap into the local door strike s power supply. A door sensor input monitors for a forced door or door ajar condition. A Request to Exit input operates the doors for people leaving the controlled area. Three separate relay outputs allow control of Door Strikes, Magnetic Locks, Gate Opener, Lights, Camera and or Alarm.
