Mounting instructions
1. Remove the MFI from its carton and discard the packaging material.
2. Place the MFI against the surface to which it is to be affixed and mark the
location of the mounting holes. We recommend mounting the MFI within a
cabinet.
It is recommended that you affix the MFI at all four of the mounting
locations provided.
WARNING
Type and source of hazard
Do not apply power to the MFI or associated components at this stage.
3. Select the appropriate drill bit according to the mounting surface / hole size
and drill the holes in the locations marked (if required).
4. Connect the cabling to the MFI PCB. Refer Section 6: Connections and
LEDs. Open the top cover before connecting cables and close after
connections done.
5. Apply power to the MFI and test its operation. This step may require
installation and programming of the access control host software and
download of the firmware instruction set. Alternatively, the firmware and
configuration may be carried out using the FLN Field Service Tool Version
2.5.3 or later.

6Connections and LEDs
6.1 Connections related to Doorset
It is recommended that you wear a grounding strap while carrying out this
procedure.
1. Connect OSDP readers to the appropriate READER port of MFI. Up to 8
OSDP readers can be connected.
Each reader must be wired correctly. Refer Section 6.2 OSDP Reader wiring.
The total resistance for each reader cable must not exceed 16.8 Ohms.
2. If required, connect the Request to Exit (REX) switch (e.g. door opener
button) to the appropriate REX input on the MFI.
3. If required, connect each door contact (door monitor) to the appropriate
D/C input port on the MFI. For example, connect the contact for Door 1.
Resistors must be connected to the wiring for each input device (this applies
to all inputs), if they are to be monitored. Refer Section 6.3 Wiring of
monitored input.
The total cable run resistance must not exceed 100 Ohms.
4. Connect each door lock to the appropriate RELAY OUT port on the MFI.
Access doors can only be connected to output relays that are controlled by
readers. (RELAY number 1-4)
5. For example, connect the lock for door 1 to the “RELAY1 OUT” connection
on the MFI. Ensure that the power supply used to drive the lock is
sufficiently rated.
6. Connect any auxiliary output devices to the AUX OUT ports (RELAY
number 5-8) on the MFI.
7. Connect any load device to the Open Collector output if required.
8. Connect the FLN wires (from the ACC-AP) to the FLN RS485 (COMM 2A
and 2B) port of MFI.
9. Connect the Power Supply Unit (PSU) to the V IN port. Ensure the polarity
of the connection is made correctly.
10. Check all jumpers.
11. Check all connections thoroughly, including the polarity of each connection.
Once you have verified all connections power can be applied to the MFI.

6.2 OSDP Reader wiring
Reader connection via OSDP with or without encryption. The readers should be
connected to the appropriate terminal blocks (A, B, -, +) of the READER port
Mapping from MFI board to the Reader ports.
Up to 8 OSDP readers can be daisy chained (from one reader to another) on the
same connection.

9Addendum
(A)Using OC outputs of MFI
MFI’s open collector outputs can be used as depicted below:
OC 1, OC 2, OC 3 points will be grounded, if they are activated from MFI to
trigger current flow through the load(s).
External power or one of MFI’s power output ports can be used for powering
load on OC points. This implies that the following options are available for
driving load on OC points.
●MFI 12V output
●MFI GL12V output
●MFI VOUT output
●External power
If MFI power output ports are used to power load on OCs, overall current usage
shall not exceed the limits (discussed in section 3.1) for each of the output port,
considering other loads that needs to be connected such as readers, door
latches and so on.
(B)EOL terminations
EOL resisters shall be enabled on MFI’s and AP’s if the cable length exceeds 20
meters.
To enable EOL on MFI’s ACC-AP connection port (Refer section 3.1
Description of Numbered Items in the Diagram - Item Number 12)
To enable EOL on MFI’s reader connection port (Refer section 3.1 Description
of Numbered Items in the Diagram - Item Number 4a)
To enable EOL on ACC-AP’s MFI communication port (Refer ACC-AP

last MFI exceeds 20m.
