Product Details

Up to 32 additional points of entry can be added to Viking’s model AES-2000/AES-2005 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 ES-3 can be used with any Viking or other proximity reader, RF transmitter, or digital keypad that outputs 26 bit Wiegand format. Up to 525 valid Wiegand codes can be programmed into the AES-2000/AES-2005, and up to 1024 access entry events are logged and stored in the AES-2000/AES-2005. Other programmable parameters, like relay activation and delay times, are also PC programmed via the AES-2000/AES-2005.

Only one pair of wires are needed to wire all 32 Entry System Door Controllers back to the AES-2000/AES-2005. This two wire CAN communication protocol allows the ES-3 to be installed up to 1 mile away. 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. Power to the ES-3 can be daisy chained from unit to unit on a single pair of wires, or simply tap into the local door strike power supply.
