Bricker,
Are the doors open or closed?
Verify (if you have the FAST) the CLC variable for FEO.
Sometimes the input at the keyswitch for recall has to be held to off or bypass for several seconds.
Broken recall keyswitch?
Do you have a bad smoke device at an upper floor or hoistway overhead?
Doors closed would mean you have to get in the car and hit door open button to DOL, and be sure doors stay open. In this scenario, the unit is still technically on phase 2 fire if equipped, then reset the main hall keyswitch.
Could be more in-depth stuff, but these are the easy, common points.
