There are a handful of Parameters to set when implementing an External Relay for use with Bells. These parameters can be sent to the clock using the Clock Tools of the Communications area.
| Option | Value |
| UseNewBell | 1 |
| ExAlarmDelay | 10 |
| ~LockFunOn | 0 |
| isSupportAlarmExt | 1 |
Once the Parameters have been sent to the clock, send the "Reboot" command as well. Rebooting causes the clock to re-examine the settings values, which will cause the clock to implement the changes.
