Mapping relays on a Four Door Controller (4DC)
The theory is that the physical relay on the Four Door Controller needs to be mapped as a DGP relay on the challenger to allow an event flag to trigger an action. This example assumes the 4DC is already being polled correctly as DGP2. Titan will be used as the software, however the programming steps are the same for other versions of software.
1. Configure the Four Door Controller Macro
In the Titan Menu, go to Challenger > Intelligent Access Controller > Controllers > Macro Logic
- Press the New button.
- Enter the Challenger No, Controller No (4DC DGP number), and Description.
- In the Function field, select Non-Timed.
- Under RULES, set the first rule to DGP Relay with Item No set to a DGP relay number of this controller (in this V8 example the relay is 33, as this is the first DGP relay on DGP 2). (Note: for Challenger 10 you just put DGP relay number to match the phisical relay number)
- Leave the other three rules blank.
- Set the Activate rule to Physical Relay, with the Item No set to the physical relay on the controller your wish to control.
- Note: Physical Relay means the number of the relay physically on the DGP, where the four on-board relays are numbers 1 through 4, and the relays on any 4-Way or 8-Way relay expansion cards begin at number 5.

2. Create the Relay
Now that we have the Four Door Controller macro, we need to create a Map Relays record.
In the Titan menu, go to Challenger > Map Relays
- Press the New button.
- Enter the Relay No as the relay we mapped previously (in this example, it was Relay 33).
- Give the relay a Description.
- Note: It is good practice to include the Door number in this description, in our case it's Door 21 (first door on DGP 2).
3. Testing the Relay
From the Control > Relay form, select the DGP relay (in this example, relay 33) by double-clicking the relay.
You can now press the Set and Reset buttons, and the relay on the Four Door Controller will respond accordingly. Ensure your Reset the relay before exiting this screen.
4. Using this Relay
With this process complete, you can now use the relay number or event flag (in this example, Relay 33 and Event Flag 101) to trigger the relay on the Four Door Controller.
Example uses are:
- Opening a Four Door Controller door using a Challenger RAS (Door Event Flag).
- Installing an Egress button on another DGP (Input to Event Flag).
- Activate this relay from a Challenger Macro.
