2. The Fire Override section sets the configuration for the device if the fire alarm is triggered only if DAS-SQL is integrated with the local fire alarm system.

3. The Network Settings options can be found here.

4. Dual Custody is used if multiple people must be present to pass through the controlled entrance. Multiple configuration options are available.

5. The encryption key is set with the initial hardware setup and can only be set one time with the hardware device. **Make sure to record the encryption key during installation as it cannot be changed on the hardware side**

6. The Device section controls authentication and output options for the related devices. The Device 1 and Device 2 tabs are identical except for the Mantrap checkbox.

**If a Nexus Duo is not used and there is only one device present, the Device 2 tab does not need to be configured**
