I haven't set up this type of device before. Too fancy for the applications I have worked with. However after reading this over, I suggest you want the "Delay Audible Alarms" mode. It is also the simplest to wire.

The positive wire on the control panel will become the switch for the fan. The negative wire that goes to control panel will just be a ground. The bell will become the coil in a relay for the fan. You don't want to run the current for the fan through the device, just the control current. Then match the switches for the time and mode. OK?
