INSTALLATION GUIDE - REMOTE ACCESS CONTROLLER RAC 4 • PK3197_10_14
Before starting installation: 
•  Ensure all components ordered 
and materials / tools required are 
available.
•  Ensure all cabling is available for 
the peripherals / components being 
installed.
IMPORTANT: 
All installations & wiring of RAC 4 
enclosure and peripherals must comply 
with all applicable local building codes 
and regulations.
CAUTION:
 Do not connect power to the enclosure 
until the end of the installation.
If installing the RAC 4 in an elevator cage 
environment, or in proximity to any other 
equipment that may generate high levels 
of electromagnetic interference, follow 
the installation requirements as indicated 
in Annex C to prevent any operational 
instability.
4.1 Pre-Installation Procedures
Step 1: Identify a secure location for 
the RAC 4 enclosure
IMPORTANT:
•  Access to the RAC 4 enclosure must be 
restricted to authorized personnel.
•  AC power must be available within 6 feet 
(1.8 m) of the RAC 4 enclosure.
•  The location temperature must be from 
32°F to 120°F (0°C to 49°C) and sheltered 
against weather hazards and dripping 
water.
•  The enclosure must be installed using 
the hardware supplied.
Identify the location for the RAC 4 enclosure 
based on the following:
•  Enclosure should be mounted at a 
workable height with clearance to 
completely open the access door.
•  The enclosure can be placed either 
horizontally in the ceiling or vertically on 
a concrete, wood, or plaster wall.
Step 2: Identify location(s) for card 
reader and peripherals
Swipe, insert and extended range contactless 
card readers must be placed within 500 feet 
(150 m) from the RAC 4 enclosure, while 
contactless card reader Model R79-1N1 must 
be placed within 40 feet (12 m) of the reader 
power source.
The card reader should be installed in an 
obvious location at an ergonomic height near 
the access door or elevator being controlled.
Swipe card reader:
The space to use the swipe reader must be 
large enough to allow for adequate swipe 
clearance.
Insert card reader:
The insert reader must be enclosed in the 
elevator wall panel, so the location should be 
in an area with workable access.
NOTE:  The minimum depth required for 
mounting of the insert card reader is 
4.5”.
Contactless card reader:
The space to use the contactless reader 
must be large enough to allow for adequate 
clearance for the card being presented to the 
reader.
Remaining peripherals:
Determine the location(s) required for any 
other RAC 4 system peripherals (REX, 
motion detector, etc) and ensure that all 
required cabling is available as required in 
following steps. Install as per manufacturer’s 
instructions and route wires to the RAC 4 
enclosure for connection to the controller 
PCB.
Step 3: Set the desired access delay
The default factory setting for the delay on 
access devices is 3 seconds. To change this 
value configure the controller PCB dip switch 
SW2 settings as per Annex A, Table 4.
Step 4: Install strain relief
One strain relief is provided in the hardware 
bag to secure the wires leading into the 
enclosure and to help prevent the possibility 
of wire tampering.
1.   Determine the routing needed for all wiring 
of the RAC 4 card reader and peripherals, 
and select the enclosure knock-out to be 
removed for installation of the strain relief.
