Product Details

The ES-1 is a door controller designed to operate a door strike or magnetic lock upon receiving a valid card read and/or keyless entry code from Wiegand devices. One ES-1, one or two Wiegand devices and a door strike or magnetic lock of your choice is required for each entry point.

The ES-1 can be used with any Viking or other proximity reader, RF transmitter, or digital keypad that outputs 26 bit Wiegand format. If two Wiegand devices are used, one can be placed on each side of a doorway to control access in both directions (entry and exit). Up to 250 valid Wiegand codes can be programmed into the ES-1.

Other programmable parameters, like relay activation, mode (normal, off, or open) and facility codes are also stored in non-volatile memory. All programming is done with a local touch tone phone. Up to three ES-1 units can be programmed simultaneously if they will be sharing all the same programming codes and parameters. Entry logging is possible with the LOG BUS data output of the ES-1.
