IEI MiniMax 3 Installation/Programming Manual Section 2: Installation
Section 2: Installation
This section contains detailed procedures and wiring diagrams for installing the IEI MiniMax 3 Access Control System. This section is
presented in the order you should follow to install the unit. Not every section is necessary for every application.
The system must be installed within the protected area in accordance with the National Electrical Code (NFPA 70), local codes, and
the authority having jurisdiction. It should also be located in an area that is accessible for programming purposes. After the installation
is complete, the cabinet door should remain closed and locked to protect the contents.
Note: Programming commands are inserted into the installation procedures for your convenience. Programming should only be done
after all electrical connections are made and the system is powered up.
2.1 Check the Packing List
Open the box and inside is a metal enclosure. The metal enclosure has a removable lid, to give you easier access when wiring. Inside
the metal enclosure is:
•1 Backplane mounted on standoffs
•1 6.5VAC Transformer
•1 Camlock with key
•1 Hardware Pack containing:
•1 Wire nuts (ORANGE)
•4 Wall anchors (BLUE)
•4 #8 ¼” sheet metal screws
•1 Set of battery cables (BLACK AND RED)
•1 Ground cables (BLACK wire with RED flush tab receptacle)
•1 Max 3 Module
•1 detachable keypad for programming (Pre-mounted to Max 3 Module)
•1 Secured Series Software Package
•1 MiniMax 3 Installation and Programming Manual
Please check the contents of the enclosure and verify all components on the packing list are present. Taking this inventory will
familiarize you with the components as well as ensure you have a complete kit.
2.2 Mount the Enclosure
The enclosure is designed to be wall mounted (surface mounted) using the supplied hardware. You must mount the enclosure on the
secure side of the door in a secured area such as a locked utility closet. Make sure it is accessible for programming and maintenance
purposes. Do not use the controller as access device to enter or exit through the door.
Mounting Procedure:
Unlock and open the metal enclosure. Notice that the enclosure lid opens from top to bottom so the enclosure lid forms a tabletop for a
convenient workspace.
. Use the supplied wall anchors and sheet metal screws to secure the enclosure to the wall.
2. Drill /64’’ diameter holes for the wall anchors.
3. Tap the wall anchors into the wall until the outer flange is flush to the wall surface.
4. Insert the sheet-metal screws ¾ of the way into the anchors.
5. Hang the enclosure by aligning the slotted holes (cut into the rear of the cabinet) with the sheet-metal screws. Space between
slotted holes; on-center 9 /6” Horizontally and 0 /8” Vertically.
6. The enclosure should now be resting on the sheet-metal screws.
7. Tighten the sheet-metal screws until they are snug.

Section 2: Installation IEI MiniMax 3 Installation/Programming Manual
2.3 Ground the Unit
Grounding the system before making any electrical connections is imperative!
By grounding the system first you not only increase personal safety during installation, but you also protect the unit from damage due
to static discharge or any other transient voltage effects. We cannot stress enough the importance of completely grounding the unit
before making any connections or even touching the backplane (the large circuit board in the enclosure). Wire as shown and plug the
transformer into a grounded electrical socket.
Page 10 of 48 Document #: 6055672, Re 1.0 D1c
Do not make any AC
Power connections
until Step 13 of the
installation.
TOUCH THE GROUNDED METAL CABINET BEFORE TOUCHING THE BACKPLANE OR
THE MAX 3 DOOR CONTROL MODULE. THIS WILL REMOVE ANY STATIC CHARGE ON
YOUR PERSON. STATIC ELECTRICITY CAN DAMAGE THE ELECTRONIC COMPONENTS
USED ON THE CONTROLLERS.
Figure 3: Connecting the GND Terminal from Transformer to the Backplane

IEI MiniMax 3 Installation/Programming Manual Section 2: Installation
2.4 Connect the RS-485 Cable from the Module to the Backplane
The Max 3 Door Control Module requires an additional three position cable to make the RS-485 connection to the backplane. This
cable is connected from P5 on the upper right corner of the module to the three position connector underneath the module on the top
right of the backplane labeled P . Simply plug one end of the cable into P5 and the other end into P on the backplane. The diagram
below illustrates how to connect the module to the backplane.

Section 2: Installation IEI MiniMax 3 Installation/Programming Manual
2.5 Wire an Electric Door Lock to the Main Relay of the Max 3 Module
The locking device is connected to terminal strip TS as shown in
the diagram on the right. The two diagrams below show how to
connect both a Maglock and an Electric Strike using an external
power supply.
For either locking device, positive voltage (V+) from an external
power source is connected to the relay common terminal (C).
When using a Maglock, connect the lock's positive side to the
normally closed (NC) terminal and the negative side to negative on
your power supply. When using an Electric Strike, connect the
lock's positive side to the normally open (NO) terminal and the
negative side to negative on your power supply.

(time = to 99 seconds)
Exit Program Mode *
Page 12 of 48 Document #: 6055672, Re 1.0 D1c
NOTES:
You must use an external power supply to power your
lock.
The relay is a FO M C D Y CONTACT, which
means there is no output voltage on the relay contacts.
When using AC voltage, polarity does not matter.

IEI MiniMax 3 Installation/Programming Manual Section 2: Installation
2.5.1 Installing a Diode to Pre ent Electrical Kickback from Lock – DC Locks Only
If your electric locking device does not come pre-installed with internal protection for electrical “kickback voltage” use the supplied
N4004 diode for DC locks only. This “kickback voltage” could possibly damage the Max 3 control module and installing the diode
could help prevent this from happening. When installing the diode, connect it across the positive (V+) and negative (V-) of your
locking device. The diode is polarized, which means the cathode mark (silver band at one end) must be connected to the positive
connection as shown below. You must connect the diode as close as possible to the locking device for it to work properly.
2.5.2 Installing an MOV to Pre ent Electrical Kickback from Lock – AC Locks Only
If your electric locking device does not come pre-installed with internal protection for electrical “kickback voltage” use the supplied
MOV for AC locks only. This “kickback voltage” could possibly damage the Max 3 control module and installing the MOV could
help prevent this from happening. When installing the MOV, connect it across the AC connection to your locking device. This device
is not polarized so it does not matter which direction you install it. You must connect the MOV as close as possible to the locking
device for it to work properly.

2.6 Connect a Secured Series Front End (SSFE) Reader to the Door Control
Module
The Max 3 supports IEI Secured Series Front Ends, which include keypads, card readers and touch chip readers. These are connected
to to the Front End terminal strip TS5. You can connect up to two readers to each Door Control Module, for In/Out operation by
simply wiring them in parallel (both readers to the same four screw terminals). Each screw terminal is labeled with a wire color (black,
red, white/black and white yellow). These correspond to the color wire on the wire harness supplied with the front end reader.
You must use a four-conductor stranded cable with overall foil shield to connect the Front End to the Door Control Module. You also
must terminate the drain wire (the bare wire inside the foil shield), from the front end cable, to the fast-tab located on the Max 3
Backplane. There is a fast-tab located under each module on the lower edge of the backplane. They are labeled FT , FT2, FT3 and
FT4. Connect the drain wire from the front ends connected to module one to FT and so on. IEI has included four ground cables and
wire-nuts to make this connection. Do not terminate the drain wire at the Front End eader. Cut off the exposed drain wire and
wrap the insulation and the foil shield in electrical tape.
Page 14 of 48 Document #: 6055672, Re 1.0 D1c
Note: The Max 3 Door Control Module must be configured to operate in Secured
Series Front End Mode. To do this, locate jumper JP2 above terminal strip TS7 and
place the jumper on both pins.

Note: If you experience problems with
front end communications after connecting
a second keypad or reader, wiring a
separate ground wire from each keypad to
the black terminal on the Max 3 DCM may
solve the issue. If this does not fix the
problem contact IEI Technical Support.

IEI MiniMax 3 Installation/Programming Manual Section 2: Installation
2.7 Connect the Primary Wiegand Front End Reader (IN Reader)
Wiegand readers are connected directly to the Front End Terminals on the Door Control Module. The primary reader (IN) should be
mounted on the exterior of the door and used to gain access into the secured area. The diagram and table below describe the
connections in detail. Please note that the Primary Wiegand Reader Data 0 wire is connected to DO PRI (Data 0 Primary) on terminal
strip TS5.
The LED connection is used to indicate status of the Main Relay and the Sounder connection is used to indicate various error
conditions. These are explained in more details in later sections.
You must use a four to six conductor stranded cable with overall foil shield to connect the Front End to the Door Control Module. You
also must terminate the drain wire (the bare wire inside the foil shield), from the front end cable, to the fast-tab located on the Max 3
Backplane. There is a fast-tab located under each module on the lower edge of the backplane. They are labeled FT , FT2, FT3 and
FT4. Connect the drain wire from the front ends connected to module one to FT and so on. IEI has included four ground cables and
wire-nuts to make this connection. Do not terminate the drain wire at the Front End eader. Cut off the exposed drain wire and
wrap the insulation and the foil shield in electrical tape.

2.9 Wire a Request to Exit (REX) de ice and Door Contact
equest to Exit ( EX) This is a normally open loop, when momentarily closed activates the Main Relay for the
length of time programmed in the Main Relay Time (command ).
Door Switch Input This is a normally closed loop that tells the Max 3 the door status. This is used for the Door
Ajar, Forced Door and Auto-Relock features.
Auto-Relock
Auto Re-lock refers to the feature that automatically locks the door one second after the door contact switch is opened. This allows
you to program a long unlock time, when required, without worrying about the door remaining open after the person has entered. No
programming is necessary for this feature, but it does require you connect a door contact switch as shown in the diagram above.
Remember you must remove jumper JP1 for the door contact input to operate.

2.10 Wire the Alarm Shunt Relay
The Alarm Shunt Relay is used when you are controlling access to a door that is monitored by an external alarm system. This relay
activates at the same time as the Main Relay (by either a valid code/card or REX) so you can bypass the existing alarm panel, as
shown in the diagram below. For this feature you must wire dedicated door contact to terminals TS6 (door contact switch input) as
shown below. The Alarm Shunt Relay remains energized until one second after the door contact switch input is closed. Remember you
must remove jumper JP1 for the door contact input to operate.

The Forced Door Relay Output alerts personnel that the door was opened without authorization. For this feature to operate you must
wire a dedicated door contact switch to the door terminals on TS6 (door contact switch input) as shown below. Remember you must
remove jumper JP1 for the door contact input to operate. If these door contacts are opened without a valid access or REX, the Forced
Door Relay energizes immediately. It remains energized until either a valid code is entered or card presented to the Front End Reader,
a valid code is entered on the Max 3 Module or the Forced Time (command 45) expires.
The diagram below shows how to switch positive power (V+) to an alarm device. The Relay is rated to handle Amp of current at
either 2 or 24 Volts AC/DC. Alarm device(s) are not included with IEI equipment.
