4. Relay Expansion Board Configuration
Configure Relay Output SW4
The relay expansion boards are factory configured to a fail secure mode by
default. In the fail secure mode, Switch 4, on each relay expansion board,
is set to Relays OFF. In this mode the relays are normally OFF in the idle
state after power up. When the proper credential is presented to the
reader the coordinating relay will turn ON and activate accordingly. If the
system loses power or the Access Override (J18) is activated, the relays
will remain OFF. In this situation, the elevator buttons will no longer be
available to the user unless the master elevator controller grants access
outside of the dormakaba system.
To reconfigure the system to a fail safe mode, power off system and set Switch 4 on all relay expansion
boards to Relays ON.
In the fail safe mode, Switch 4, on each relay expansion board is set to Relays ON. At the next power up,
all relays will be normally ON in the idle state at power up. When the proper credential is presented the
coordinating relay will turn OFF accordingly. If the system loses power or the Access Override (J18) is
activated, the relays will switch states and turn OFF. In this situation, all buttons in the elevator car will
be available to the user without the requirement of presenting a credential to the reader.
NOTE: All relay expansion boards must be configured the same. If the relay expansion boards are
configured differently (one set to Relays ON, another set to Relays OFF) the system will not function
properly. The system must be power cycled for the configuration change to take effect.
5. Relay Expansion Board Switch Selection
Each REB is factory configured to have a unique ID. If service to a
REB is ever required, ensure to set the switch to the same ID of the
PCB you are replacing.
6. Wire relay expansion board outputs. Refer to Annex B for sample wiring diagram.
The relay expansion board provides 8 relay contacts for wiring and control of relay-enabled elevator. The
board only provides normally open or normally closed dry contacts, so no power is provided by the
board.
Up to 8 expansion boards can be used for total control of 64 floors (secure stops). The relay outputs are
at the wiring input of each three-terminal connector (1, C, 3) on the expansion PCB as well as being

indicated on the label on the inside of the door. Several floors can be controlled by one relay (one secure
stop).
The relays in the RAC5 MFC are UL rated and are capable of a maximum switching of 30 VDC @ 1A. For
time duration of relay state see Ambiance System Settings, under Security and Lock Access.
As wiring of relay-controller equipment may vary between products, please refer to the product
NOTE: Refer to Annex B, Figure 8 for specific relay expansion board bypass switches.
• If relay output configuration Switch 4 is set to RELAYS OFF and bypass switches are ON, the
relays are bypassed, and the green LED associated with that relay is turned ON
• If relay output configuration Switch 4 is set to RELAYS ON and bypass switches are ON, the
relays are bypassed, and the green LED associated with that relay is turned OFF
• If relay output configuration Switch 4 is set to RELAYS OFF and bypass switches are OFF, the
controller PCB can activate the relays. The associated LEDs turn ON during relay activation
• If relay output configuration Switch 4 is set to RELAYS ON and bypass switches are OFF, the
controller can activate the relays. The associated LEDs turn OFF during relay activation
• When the power of the RAC5 MFC is too low (power failure), the controller PCB stops
functioning and the relays will be powered down. Any peripheral connected to the relays will
then be either in fail safe or fail secure mode, depending on the wiring
