Figure 12: Relay Expansion Board Outputs Wiring
Note 1: Make sure all the wiring is complete, including the ribbon cable, before applying power to the RAC 4XT to ensure proper Relay
Note 2: The relay outputs are "fail safe". Accordingly, they are energized in their normal state and the relay status LED is ON. Upon power
Note 3: If the Fire Alarm Panel connection is not required, place a jumper wire between pin 3 and 4 of J18.
Note 4: In this example, the Normally Open relay outputs are used. Relay 2 controls access to Floor 7 and Relay 3 controls access to Floor
Note 5: For normal operation, set the relay override switches to the Off position (the relay status LED will be ON). Set the relay override
