Can the Bosch access control system provide me an after hours contact closure telling me someone has used their card after hours? 
  
The ACCP is not my system. I am the HVAC guy. I need to know if the tenant is in the building after hours. They are not pushing my HVAC overide button so I don't know when they are there. 
  
I thought about CT's on the lighting circuits but that would be expensive. 
  
I just need an output contact closure telling me the tenant is in the Bldg after hours. 
  
Thanks
