# Reader behavior

In everyday operation, the Reader:

1. Is lit solid red or green to indicate whether the door is locked or unlocked
2. Flashes green 3 times to indicate that a credential has successfully unlocked the door
3. Starts a countdown indicating how long the door will be unlocked for to allow it to be opened
   1. Set timings for a door in the [door settings](https://docs.accessia.com/site-setup/adding-doors/door-settings)
   2. If UWB is enabled, the countdown is replaced by an infinite chase for as long as the user is standing within proximity to the door

When the door is opened, the lock either:

1. Engages almost immediately so that the door is locked when it's closed. The Reader returns to being lit red
2. Stays unlocked for the full unlock duration before it locks

Configure the Reader behavior in the [door settings](https://docs.accessia.com/site-setup/adding-doors/door-settings)

1. When a REX is used to unlock the door, the Reader stays lit red
2. The Reader can also be set to flash red if a door is held open or if there is a door forced event. Set this in the [door settings](https://docs.accessia.com/site-setup/adding-doors/door-settings)
