The ES-3 Entry System Access Controller monitors the Wiegand device (ie. proximity card reader) for 26 bit Wiegand data.
When data is received, it is converted into CAN data and sent (up to 2000 feet away) to the AES-NET board through the
shared CAN two wire pair. The AES-2000 compares the data against its programmed data base and communicates back
to the originating ES-3 whether access is granted or not. If access is granted, Relay 1 and Relay 2 will activate per their
programmed delay and activation times. The Entry Point Location, time, and Card Number will all be logged in the AES-
2000. Relay 1 operates first and should be used to operate the door strike or magnetic lock. Relay 2 can be delayed from
Relay 1 to operate a gate / door opener, or a second door strike or magnetic lock for double entrance doors. Relay 2 may
also be programmed with longer times to operate courtesy lights or a camera.
If a "Push to Open" button, push bar switch, or motion sensor activates the Request to Exit input of the ES-3, the relays
will activate the same as if access is granted. No data is logged on a Request to Exit event.
If a door sensor switch is wired to the Door Sensor input of the ES-3 and the door remains open longer than the pro-
grammed Door is Ajar timer, Relay 3 will activate for either 1 second or until the door closes (programmable). This can be
used to set an alarm, light a security panel lamp, turn on a camera, etc.
If both a request to exit device and a door sensor switch are used, a Forced Door alarm condition may be selected. If the
door is opened other than by the ES-3, Relay 3 will activate for either 1 second or until the door closes (programmable).
LED’s are provided for the 2 inputs and the 3 relay outputs. Each LED is located behind its associated screw terminals.
The LEDs will remain off showing the idle state, and turn on when its associated input/output is triggered/activated.
