Fig. 4.1 Connection to Power Supply
The voltage supply for EverAccess controller can handle a range of DC 9V ~18V. The maximum current draw of the controller is 500 mA. If the backup battery is connected to the controller, a power supply with DC15V output is required. The power supply in the EverAccess enclosure is DC15V. In addition, the controller provides a 12V power supply for the card readers. It should be noted that if a controller powers multiple card readers, the current draw will be increased. The total current draw can be calculated as below:
Currentcontroller = 500 + currentreader ⋅ numberreaders connected to controller
Important Tips: The voltage supply should be located no more than 2 meters from the controller. Also, electric locks and alarm devices MUST be powered separately. The controller’s power supply can power the controller and modules, and the card readers, but NOT the locking hardware or alarm devices.
