I've a situation that probably has been encountered by others as well. We are using contact closure to control door lock with buzzer. The issue arises when two or more employees press the button at the same time, which turns the closure back off. We have had training after training to teach the employees to communicate who will be opening the door, but it never fails, the door/buzzer gets turned on/off/on/off/on/off repeatedly before the [now disgruntled] customer is finally let in. I thought about creating a user that is forwarded to the short code for relay pulse and pressing the button for that user rather than the relay. But then, the door is open/buzzing for 5 whole seconds (4 seconds of buzzing too long). Has anyone else found a better solution?
