Timed Response

Our Security Office has some concerns about Timed Response. 
 
If our Security Team has a different Timed Response policy that is different from WCAG 2.0 (Situations A, B, and/or C), can we still pass WCAG 2.0 for Timed Respones, Checkpoint (2.2.1)?
 
If it is conditional, what are the conditions?
