3.0 Installation
This section contains detailed unpacking and installation procedures and wiring diagrams for the IEI Hub
MiniMax/MiniMax II Access Control System. This section is presented as steps and should be followed in
the order indicated. Not all steps are necessary for every application.
Note: Programming commands are inserted into the installation procedure for your convenience.
Programming should only be done after all electrical connections are made and the system is powered up
in step 13.
Step 1: Unpack the Hub MiniMax/MiniMax II and Check the Packing List
Open the box and inside is a metal enclosure. The metal enclosure has a removable lid, so the installer
has easier access when wiring. Inside the metal enclosure is:
• 1 Hub MiniMax Backplane mounted on standoffs in cabinet
• 1 16.5VAC Transformer (see section 1.2 for approved transformers)
• 1 Camlock with key
• 1 Hardware Pack containing:
o 1 Wire nut (Red)
o 1 Wire Nut (Orange)
o 4 Wall anchors (BLUE)
o 4 #8 1¼” sheet metal screws
o 1 set of battery cables (BLACK AND RED)
o 1 Ground Cables (BLACK wire with RED flush tab receptacle)
• 1 Hub Door Control Module
• 1 detachable keypad for programming (Pre-mounted to Hub Door Control Module)
• 1 Secured Series Hub MiniMax/MiniMax II 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.
Step 2: Mount the Hub MiniMax/MiniMax II Enclosure
The Hub MiniMax enclosure must be mounted on the secured side of the door and must not be used as
an access device as a means of gaining access or egress through the door. Ideally the enclosure should
be mounted in a secure area such as a locked utility closet. However, this is not always available so
wherever you decide to mount the enclosure make sure it is accessible for programming purposes.
Mounting Procedure:
Unlock and open metal enclosure. Notice that the enclosure lid opens from top to bottom and if you
mount the enclosure horizontally the enclosure lid will form a tabletop and a convenient workspace. You
can also mount the enclosure vertically (see section 4.1).
1. Use the supplied wall anchors and sheet metal screws to secure the Hub MiniMax Cabinet to
the wall.
2. Drill 11/64’’ 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 Hub MiniMax Cabinet by aligning the slotted holes (cut into the rear of the cabinet)
with the sheet-metal screws. Space between slotted holes; on-center 9-11/16” Horizontally
and 10-1/8”” Vertically.

6. The Hub MiniMax Cabinet should now be resting on the sheet-metal screws.
7. Tighten the sheet-metal screws until they are snug.
Step 3: Ground the Hub MiniMax/MiniMax II
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 Hub MiniMax from damage due to static discharge or any other transient voltage effects. We
cannot stress enough the importance of completely grounding the Hub MiniMax 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.
Do not make any AC
Power connections
until Step 13 of the
installation.
TOUCH THE GROUNDED METAL CABINET BEFORE TOUCHING THE BACKPLANE OR
THE HUB MINIMAX CONTROL MODULE. THIS WILL REMOVE ANY STATIC CHARGE ON
YOUR PERSON. STATIC ELECTRICITY CAN DAMAGE THE ELECTRONIC COMPONENTS
USED ON THE CONTROLLERS.

Step 4: Connect the Hub Door Control Module to the Backplane
The Hub MiniMax Backplane supports one Hub Door Control Module, which is provided with the unit.
There are three nylon standoffs on the Backplane to support the module and a ten-pin connector labeled
“J1.” On the Hub Door Control Module there is a corresponding ten-pin connector labeled “S1.” To
connect the module to the Backplane, slide the S1 connector onto the J1 pin rail located on the
Backplane, and snap the module onto the standoffs.

Step 5: Wire an electric door lock to the MAIN RELAY of the Hub Door Control Module
NOTE: All locking devices must be U.L. Listed.
MAIN RELAY Terminal Block
NOTE:
All four relays (Main, Alarm Shunt, Forced
Door, Door Ajar) are FORM C DRY CONTACT, which means there is no
voltage on the relay contacts. These relays can
be used on a dry contact loop or switch one leg
of power to an external device as shown in the
illustrations below.
output
Lock+ and Lock- represent the Lock Output screw terminals on the backplane (TS2). If you are using
AC, polarity does not matter. Please see the next section for the Lock Output details. You must use an
external, U.L. Listed Access Control, Power Limited Power Supply with a minimum of four (4) hours of
backup power for 24 VAC/VDC operation, or if your lock draws more than 600mA.
Programming the MAIN RELAY TIME: (default MAIN RELAY UNLOCK TIME is 05 seconds)
The Hub MiniMax Backplane has two screw terminals (TS2) for a lock output to supply power to a locking
device. This output can supply either 13.8 VDC or 16.5 VAC, by using the AC/DC switch on the
backplane; the maximum current draw is 600mA.
The AC/DC switch is located about 2 inches above the lock screw terminal and underneath the module.
You must remove the module to access the switch. There is a green LED (LED 4), labeled “LOCK,” to
indicate that there is voltage present at the screw terminals.
• The lock output is only 13.8 VDC or 16.5 VAC. If your lock requires a different voltage, such
as 24V AC/DC, you must use an external power supply.
• This is a voltage output only; the main relay to control the locking device is located on the
module.
• The terminal strip is labeled “LOCK+” and “LOCK -.”When the switch is in the AC position,
there is AC voltage present, and “LOCK -” cannot be used as ground.
• If you are using an AC lock with a battery backup on the system and the main power is lost,
then the AC lock does not operate.
5B: Auxiliary Output
The Hub MiniMax Backplane has two screw terminals (TS2) for an auxiliary output to supply power to any
accessory devices (for example, a Forced Door or Door Ajar alarm). This output can supply 13.8 VDC
only, with a maximum current draw of 100mA.
The terminals are labeled “AUX -” and “AUX +” and are located next to the lock output. A green LED
(LED 5), labeled “AUX,” indicates that there is voltage present at the screw terminals.

Step 6: Connect a Front End Reader to the Hub Door Control Module
The devices used at the door to gain access are Front End Readers (not included). IEI manufactures
several to choose from, such as: keypads, magnetic card readers, proximity card readers and touch chip
readers. No programming commands are entered at the front end. The Front End Reader is only
able to send access information from the door to the Hub Door Control Modules.
Choosing the correct front end for the application is important.
IEI manufactures light, medium and heavy duty Front End Readers.
The Hub Door Control Module can support 1 or 2 Front End Readers on a single door for IN and OUT
operation. Simply wire the two Front End Readers in parallel at the door.
On the Hub Door Control Module there is a four screw terminal block labeled FRONT END.
Each of these screws is labeled with a color and they connect to the corresponding color of the fourconductor wire harness that is included with the Front End Reader. The connection between the Hub
Door Control Module and the Front End Reader is made with four-conductor stranded with overall foil shield type cable (not included). You must use this type of cable to ensure signal integrity.
After you have made your connection it is also vital to terminate the drain wire of the cable. The drain
wire is a bare wire that runs the entire length of the cable inside the shield and along side the other fourconductors. This drain wire is to be terminated at the fast-tab (TAB1) located on the Hub MiniMax
Backplane beneath the Hub Door Control Module. IEI has included a ground cable and wire-nut to make
this connection.
Do not terminate the drain wire at the Front End Reader. Cut off the exposed drain wire and wrap
the insulation and the foil shield in electrical tape.
If you are not sure which front end to use, call the IEI Sales Dept. at 1-800-343-9502.
