I have a requirement to install an access control system on the door to a Gym. I need to be able to open the door from 10am to 4pm but at all other times the card would be required. I have looked at the ACT prox 5 and the paxton compact vandal resistant but cant see how i can open the door for the required times. I plan on using a yale lock and a release and wonder if i need to use an exit button when my members can just open the lock? Am i missing something here? I dont want to spend a fortune but i need something reliable and easy to manage Thanks Geoff
