Can a lock be powered by the Door Controller (ADC-ACC1-17) when using Power over Ethernet (PoE)?

Yes. A lock can be powered by a door controller while using Power over Ethernet (PoE) by jumping a wire from the VO terminal on TB4 to the desired relay terminal.

In the example below, the 1-C terminal from TB5 is being used. For more information regarding the setup of powering the controller using PoE, see Door Controller (ADC-ACC1-17) - Installation Guide. 

Important: Verify devices receiving power from the controller's VO terminal do not exceed a sum of 650mA.
