2 Product Description
2.1 Features
The RAC5 MFC is designed to operate either online or stand-alone elevator control units (ECUs). It provides
access control and secure stops for multiple floors and functions with RAC5 NFC wall readers and AMBIANCE
features. The system can control any RFID ECU up to 1,000 feet (300m) away when using the RAC5 MFC
system.
NOTE: For installation of the contactless reader of distances greater than 1,000 feet (300m) please contact
dormakaba Canada Inc. Technical Support.
The Contactless Card Reader can be mounted directly on the inside of the elevator car, typically on the elevator
call button panel. For surface mount, the surface area required for the contactless reader is 5"W x 5"H x 2"D
(12.7 x 12.7 x 5cm, 2" depth behind panel required). The RAC5 MFC is an access control solution that can operate
2 individual card readers, provides multiple relays, and much more as per the feature list below. See Figure 1 for

4.1 Pre-installation Procedures
1. Identify a secure location for the RAC5 MFC enclosure.
•Access to the RAC5 MFC enclosure must be restricted to authorized personnel
•AC power must be available within 6 feet (1.8 m) of the RAC5 MFC enclosure
•The location temperature must be from 0 to 49 °C (32 to 120 °F) and sheltered against weather
hazards and dripping water with relative humidity conditions less than 85% at 32 °C (90 °F)
•The enclosure must be installed using the hardware supplied
•The enclosure should be mounted at a workable height with clearance to completely open the
access door
•The enclosure can be places either horizontally in the ceiling or vertically on a concrete, wood or
plaster wall
2. Identify location(s) for contactless readers.
•Card readers must be placed within 1,000 feet (300 m) from the RAC5 MFC enclosure
•Readers should be installed in an obvious location at an ergonomic height near the access door or
elevator being controlled
•The space to use the contactless reader must be large enough to allow for adequate clearance
for the card being presented to the reader
3. Install strain relief.
•Strain reliefs are provided in the hardware bag to secure the wires leading into the enclosure and
to help prevent the possibility of wire tampering
a) Determine the routing needed for all wiring of the RAC5 MFC card readers and
peripherals and select the enclosure knock-out(s) to be removed for installation of the
strain relief(s)
b) Remove the selected knock-out(s) using a hammer and screwdriver / awl, and from the
inner side of the enclosure, tap out the small metal disc
c) Based on the amount of wires to be routed, attach the appropriate strain relief to the
enclosure as shown in Figure 5. Do not attempt to route an excessive amount of wires.
If extra strain reliefs are required, please contact dormakaba Canada Inc
Figure 5 – Strain Relief
4. Ensure that Dip Switch SW2 has Test Mode switch setting (SW4) is set to OFF.

4.2 Installation and Wiring Procedures
1. Mount the RAC5 MFC enclosure
a) Install the enclosure in the desired location using the appropriate items from the hardware bag
NOTE: For easier access, we recommend removing the access door prior to installation.
Figure 6 – Enclosure
2. Mount the contactless card reader.
NOTE: All readers are rated IP 54.
a) Remove the back plate and use it to mark the holes for the cables and screws
NOTE: Refer to Annex H of this manual for elevator panel preparation for mounting readers.
b) Drill the holes in the wall according to the diameters indicated on the drilling template in Annex
H, based on the type of surface the reader is being installed on.
3. Connect peripheral wiring.
Do not exceed the maximum cable length indicated by the manufacturer of the
products being connected. In addition, the wire used to connect the peripherals to
the controller PCB must be of the proper gauge and type as specified by the
manufacturer.
Every wire must pass through a strain relief as connected in the pre-installation
procedures. dormakaba Canada Inc. does not provide technical or field support
for third party locking devices. Please consult the device manufacturer for
support.
NOTE: The maximum recommended wire length is the approximate wire length that causes a 5%
voltage loss in the wire, using a 12-volt locking device at the rated current included.
a) Fire Alarm Panel: Refer to Annex G, Figure 14 for detailed wiring
i. Remove the jumper wire connected between pins 3 and 4 of connector J18 on the
controller PCB and complete the fire panel installation as per manufacturer’s
indications
b) Tamper Switch to Premise Alarm System
i. To wire the tamper switch to the premise alarm system, disconnect the wires on
controller PCB connected J7 pins 1 & 2 and run a 2-connector cable from the
switch to the premise alarm system

IMPORTANT

12-2020 dormakaba Canada Inc. RAC5 MFC Installation Guide – PK3738 | 12
The tamper alarm switch’s polarity is such that when the door is
closed, the switch itself is also in a closed state. Ensure that the
wiring to the premise alarm system is done accordingly to
prevent false alarms.
4. 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.
As wiring of relay-controller equipment may vary between products, please refer to the product
manufacturer’s instruction booklet.
NOTE: Refer to Annex B, Figure 8 for specific relay expansion board bypass switches.
•If bypass switches are ON, the relays are bypassed and the green LED associated with that relay
is turned ON
•If bypass switches are OFF, the controller PCB can activate the relays. The associated LEDs turn
ON during relay activation
•When the power of the RAC5 MFC is too low (power failure), the controller PCB stops
functioning and the relays on the controller PCB or the expansion board will return to their
normal state. The normal state is defined as relays OFF. Any peripheral connected to the relays
will then be either in a normally open (NO) or normally closed (NC) state, depending on the
wiring
5. Install elevator controller.
Each Expansion board contains 8 dry relay contacts. Up to 8 expansion boards can be used for total
control of 64 common areas. The relay outputs are at the wiring input of each three-terminal connector
(NO, COM, NC) 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 common area).
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 change, please refer to Annex B, Figure 8.
6. Connect the power adapter.
NOTE: Dependent on the countries’ electrical power requirements, follow the directions below for the
power adapter required. Refer to Annex B, Figure 8 for detailed wiring.
a) International Power Adapter
i. Attach the appropriate AC outlet prong to the power adapter
ii. Route the power adaptor wires into the enclosure and secure the wire (recommended
with tie wraps)
iii. From the inside of the enclosure, crimp the fork terminals supplied in the hardware bad
to the end of each wire
iv. Connect the fork-terminated wires to the power supply input as shown in Annex B,
Figure 8
b) North America Power Adapter
i. From the inside of the enclosure, connect one end of the fork-terminated wires to the
power supply inputs as shown in Annex B, Figure 8
IMPORTANT

12-2020 dormakaba Canada Inc. RAC5 MFC Installation Guide – PK3738 | 13
ii. Route the wires out of the enclosure to the AC power source and secure the wires
(recommended with tie wraps)
iii. Crimp the fork terminals supplied in the hardware bag to the end of the wires and
connect them to the power adapter screw terminals

12-2020 dormakaba Canada Inc. RAC5 MFC Installation Guide – PK3738 | 14
7. Complete the installation.
a) If the access door was removed, reinstall the door to the RAC5 MFC enclosure
b) Bend the two tabs on the door to a maximum of 30 degrees as shown in Figure 7
Figure 7 – Door Tabs
c) Connect the LED wire harness from the power supply to the access door LEDs as indicated
below and in Annex B, Figure 8
NOTE: The wires must be connected with the proper polarity. Once the terminals are installed,
they are designed to have a tight fit so removal may damage the LEDs.
LED Description Location on Door ‘+’ Terminal Connection ‘-’ Terminal Connection
Power Status Top Red Orange
Battery Status Bottom Red Yellow
Ensure that the proper connections are made (e.g. red to red, black to black).
d) Plug the power adapter into the AC power source and/or turn on the main AC power to the
system
