Note 1: Make sure all the wiring is complete, including the ribbon cable, before applying power to the RAC 4XT to ensure proper Relay
Expansion Board functionality.
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
failure, or when the Fire alarm input is activated (when connected to a Fire Alarm panel), the relay state will change and access will
be automatically granted. The relay status written (NC or NO) is correct when unit is powered.
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
8. Actual wiring is specific to each application.
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
switch to ON to override the relay (the relay status LED will be OFF).
