Setting up an AIC (Access Initiated Control) to turn on an AHU or other systems

Product Line

TAC INET

Environment

• Access Initiated Controls
• Event Sequence

Cause

Access Initiated Controls are used to fire a DO on any entry or exit event from the security system. This can be used to accomplish just about any sequence of events, but it most commonly used for after hours enabling of HVAC equipment upon badging in.

Resolution

1. Define all the points in the database. Then choose one as the AIC Trigger point and define an "Event Definition" on that point
   
2. This is how the "Event Definition" looks
   
3. Close out of the Controller Summary and Select Edit>Controller>Event Sequences
4. Create a New event sequence.
5.  Since the AIC Trigger is also an external point that starts the AHU you do not have to start that point. However, you have to stop that point. In my example here the AIC runs the points for 3600 seconds and stops the AHU followed 5 seconds later stopping each of the Floor Lights. If the AIC Trigger were an internal DO, you would need to also trigger the AHU S/S
   
6. Once you have programmed your Event Sequence, you can test it by manually triggering the DO point.
7. When everything works correctly, select Edit>Controller>Access Initiated Control
8. Create a new AIC
9. You will notice the Trigger point is the AHU S/S (DO). This DO is triggered from a Reader Entry by a valid card
   
10. This is where you define which door reader the AIC is triggered from. If desired, you can have several doors such as all perimeter doors trigger the AIC.
    
11. This is where you select which person is allowed to trigger the AIC with their card read. In this example the only person allowed to trigger the AIC is Fred Flintstone. You can also select the "All individuals in Range" checkbox in the AIC editor to allow all individuals from a specific tenant to trigger this AIC.
    
12. Once you have created the AIC you can test your programming. Remember that the AIC piece is only supposed to trigger the DO and the event sequence will actually turn everything else off or on.
