Final product labelling
FCC Label location is on the “Door RFID Antenna”
because Electronic Lock RFID ISO MT is an OEM product
for locker manufacturers and not for the final customer.
At the time of delivery the label is clearly visible.
Locker manufacturers integrate this product (Electronic
Lock RFID ISO MT) into a final product (locker) and are
responsible for proper labelling of the final product
Therefore final product’s label must include also a
statement “Contains FCC ID: 2ABT8003P1143”.
Product description
Metra Electronic Lock RFID ISO MT combines a standard proven Metra Electronic Lock with RFID Lock
Driver and Metal Door RFID Antenna while MEW Controller is used to drive it.
Electronic lock is a reliable electro-motor driven lock. It is not a self-latch and electro unlatch model,
but controls both, locking and unlocking. Electronically controlled locking means that there are no
uncertain situations and that lock performs a self-test for unlocking on each cycle. Only hi-tech, non-
corrosive, minimum maintenance parts are used. Patented ball-shape bolt and adjustable door strike
ensure unlocking also under considerable pressure in any direction, thus compensating for shabby
cabinets and hinge wear. RFID lock driver drives and monitors electronic lock connected to it while it
is also a user interface. Build in ISO RFID media reader in combination with Metal Door RFID Antenna
reads ISO 15693, ISO 1443A, ISO 14443 B and Mifare RFID media and it is suitable for metal door and
non-metal door from thickness of 18 millimetres up to 30 millimetres.
Metal Door RFID Antenna boosts and focuses the RFID media reader’s antenna field and can be
installed into a plastic housing such as Metra Metal Door Strike or it is integrated directly into the
door.
Electronic Lock is highly secure, with lock’s holding force over 1000 N (depends also on cabinet
structure) and designed to give an alarm signal even before* a break-in occurs (*depends also on the
cabinet, usually when force exceeds 800 N) giving extra time to react. Alarm notification is triggered
even if the strike has been pulled out from the door and remains in the lock. When unlocked the
built-in ejector pushes the door to open.
Multiple Electronic Locks RFID are connected to the MEW Controller which supports emergency and
security features: a pushbutton for emergency opening of all Electronic Locks RFID connected to it; in
case of attempt of break-in an alarm message is distributed over Metra Network Controller to LAN /
WAN and Metra software.

Lock position
The lock position has to be identified before the process of wiring. General recommendation is that
the lock should be positioned near to the handle, so the users are operating the locks as directly as
possible. Position may thus vary due to the locker construction, vertical position, etc. The screws are
not supplied since they vary in size and type for different locker constructions and materials.
Wiring
Electronic Lock RFID is connected to the connection plate which is part of a Metra EasyWire Network
main line, by six-wire flat cable. For main line connection a three-wire cable is used. The lock, uncut
wires, connectors and connection plates are supplied separately for adjustability to different
situations (wire - lengths), easier process of wiring during installation and later maintenance.
Different types of connection plates are available to suit different locker model. First identify the
position of the locks and corresponding controller (up to 16 locks to one controller). Find the most
suitable way for the wires from the controller to its locks and install the cables. Be sure to leave cable
long enough to be connected to the lock before mounting it (approx. +5 cm).
Maximum length between MEW Controller and Electronic Lock RFID is 50 metres; 3 wire line and 6
wire lock connection cable combined while 6 wire connection cables should not be longer than 5
metres.

Link 2 connection plates
Wiring schematic example using “Link 2” connection plates. Link 2 connection plates are used where
there full height lockers. Schematic bellow shows one sided bank of lockers with 2 lockers per locker
block.
Using Link 2 connection plates Electronic Locks can be pre-connected. Connection with 6 pole flat
cable from lock to connection plate can be made in factory and on site only EasyWire main line is
connected with pre-fabricated 3 pole connection cables.
Although the lock has been designed for humid environments, it should not be exposed to the water
flow such as condensation or direct cleaning gush. To avoid the condensation or other eventual
water dripping into the lock via cable, foresee the drip-off loop of a cable before the connector.

Crimping the connectors
Six-pole flat cable connectors
Tools required: To crimp the connectors you need
crimpers for IDC connectors (left) or Metra special
connector crimper with charger (bottom) (both can be
purchased from Metra on request) and a sharp knife or
OLFA cutter.
Connector Crimper with Charger →
STEP 1:
Find the PIN1 marker.

Page 10
Electronic Lock RFID ISO MT Technical Manual
STEP 2:
Place the connector on the cable so that marker is on the
red wire. There are two possible ways to do it, so mind
also the orientation of the leading dent. To achieve a
good quality contact on all wires, the connector should
be perpendicular to the cable and the end of the cable
should be overhanging the connector for a few mm.
STEP 3:
Place connector into pliers and crimp the connector till it
clicks.
STEP 4:
Cut the overhanging part of the cable on the lock side
with a sharp knife or an OLFA cutter, flat with connector
side.
STEP 5:
Repeat the same procedure on the other side of the cable.
STEP 6:
Connect the Electronic Lock RFID.
NOTE 
Pay attention to connector’s orientation. Flat side of the
connector should be orientated towards the back side of
the lock.

STEP 7 (OPTION A):
Placing the cable under the lock. Twist the 6-wire cable in
the rabbet at the back side of the lock as shown on the
picture (two options –depends of the cabling).
STEP 7 (OPTION B):
Placing the cable under the lock. Twist the 6-wire cable in
the rabbet at the back side of the lock as shown on the
picture (two options –depends of the cabling).
STEP 8:
Connect the other side of the cable to the connection
plate.
NOTE: Example shows Link 8 connection plate.
Three-pole EasyWire cable connectors
Tools required: To crimp the connectors you need
special crimping pliers (can be purchased from Metra on
request).

STEP 1:
Separate approximately 4 centimetres of wires on a 3
pole 0.75mm2cable.
STEP 2:
Place the connector in the pillars as shown on the photo.
NOTE:
Each pin on the connector is marked with a number from
1 to 3. Some connectors may have markings on the back
side while some on the front side.

STEP 3:
Start by crimping the first (red) wire.
NOTE 
Make sure that you push the cable far enough so it has a
firm contact.
Slide the connector to the next position and continue
with the next (white) wire and finish with the last (blue)
wire.

Page 13
Electronic Lock RFID ISO MT Technical Manual
STEP 4:
Repeat the same procedure on the other side and/or in
the middle of the cable.
Photo shows a middle connector. Middle connectors can
be put in the middle or at the ends of the cable.
STEP 5:
You should end up with two or more connectors on a
cable.
Photo shows one end connector (left) and one middle
connector (right).
STEP 6:
Connect both ends of the cable to the connection plate
and/or MEW Controller.
NOTE: Example shows Link 8 connection plate, main
connection cable with middle connector and one 6 pole
cable.
Adjusting the ejector spring force
Depending on the door size and type of the hinges you might need to adjust the spring force. Ejector
is important part of the lock and should be able to push the doors open when unlocked. For the great
majority of locker and hinges type factory settings (normal spring force) are in order. However in
some cases (very small doors, spring - shut hinges, etc.) the spring might need to be adjusted. There
are two stronger positions and two weaker positions (from approx. 0.5 to 1.5 times of original force).
With this intention a 2.5/16 mm screw is supplied. Be sure to screw it all the way in so the head is
level with the lock base.
For stronger spring, simply screw it into one of the two positions on the bottom of the body (see
picture) the one closer to the ejector end being the stronger one ("A").
For weaker - shorter ejecting travel, first compress the spring totally with the thumb and then screw-
in the screw, the position closer to the ejector end now means less ejecting travel (compress &
position "A").

Page 14
Electronic Lock RFID ISO MT Technical Manual
NOTE 
Do not over-compress the spring (force ejector inside the
lock), as you might damage the switch!

Mounting the lock
General rule is that the lock is better to be placed a bit forward of the closed inner plane of the door
and should never be even a fraction back from that plane.
NOTE 
With the term inner plane of the door we refer to the surface on which the door strike will be placed
and should be able to completely compress the ejector and touch the lock front. All eventual
parameters such as rubber bumpers, bent doors, hinge type, euro deposit pad, etc. should be taken
into consideration.
Mounting holes for the Electronic Lock RFID should be predrilled in factory according to the
specifications in appendices.

Page 15
Electronic Lock RFID ISO MT Technical Manual
OK –Lock tip is even with the
inner plane of the door. The
door will reach the lock tip.
Locking is possible.
OK –Lock tip is over the inner
plane of the door. The door will
reach the lock tip. Locking is
possible.
WRONG! –Lock tip is behind
the inner plane of the door and
the door CANNOT reach the
lock tip. Locking is NOT
possible.
The lock body should be mounted first and then the door strike accordingly. The body is placed on
the locker side (for very narrow doors can be also top or bottom). Drillings should be done in
accordance with the drawing and the screw type. Insert the connector, fold the extra wire (see
"wiring") and screw the lock firmly.
NOTE 
Do not over-tighten the screws as they can deform the lock. This may stop it from working and such
damages are NOT covered by warranty!

Page 16
Electronic Lock RFID ISO MT Technical Manual
NOTE 
If the edge of the locker door is not overlapping the inner edge of the locker compartment for at
least 6 millimetres a spacer for the lock is required. As a spacer different solutions are possible.
Spacer can also be used to hide the connection cable.

Procedure
STEP 1:
Mounting holes for electronic lock should be predrilled in factory according to the specifications in
appendices and according the requirements described in this chapter.

Page 17
Electronic Lock RFID ISO MT Technical Manual
STEP 2:
Fix the lock in place with 4 screws. NOTE: Screws are not supplied by Metra.
Mounting the strike
STEP 1:
Mounting holes for door strike should be predrilled in factory according to the specifications in
appendices.

Page 18
Electronic Lock RFID ISO MT Technical Manual
STEP 2:
For easier mounting first stick the plastic cover over the metal pin to the plastic base as shown.
STEP 3:
First fix the strike with two screws. Use supplied washers between the screw and plastic strike body.
Then fix the front cover including the antenna and the protective plastic. Use the right length
(according to the door thickness) self-tapping screws. When screw is tightened its head should be in
line with the base. NOTE: Screws are not supplied by Metra. Consult with Metra before choosing the
screws.

Page 19
Electronic Lock RFID ISO MT Technical Manual
Place Metra mounting jig on the loop and firmly close the
door to position the strike and then tighten the screws.
Do not over-tight the screws, the wire loop should still
move freely. Remove the mounting jig.
CORRECTLY TIGHT SCREWS
Try moving the Wire loop left and right in the screws are
correctly tightened, the wire loop should be able to
move.
NOTE: If the lockers are precisely made and quality hinges are used the strike position does not vary
from one to another. According to strike position in the first locker all remaining can be positioned
the same just on optical evaluation to speed-up the assembly procedure. Final corrections can be
done during functional test of the locker if needed.
Final operational test of the locker

Page 20
Electronic Lock RFID ISO MT Technical Manual
Final check of the locker and mounting should be done after the lock is operational –connected to
the driving or test unit.
CHECK 1:
Press the ejector to check the operation. The motor
should operate swiftly. If not, check the wiring or loose
the screws a bit.
CHECK 2:
Close the doors. When closed and locked, the doors
should have a fraction (1mm) of a "free movement"
under the spring.
Electronic Lock set-up
MEW Controllers have at least two operating modes: Construction and Normal.
Enter the Construction mode of operation. Consult appropriate MEW Controller Technical Manuals
for details.
First reset the indexes on the connected Electronic Locks
RFID by pressing and holding the PARAMETERS REQUEST
button for more than 8 seconds –untill the second
acoustic signal is generated. When you release the
button three short acoustic signals are generated and all
connected Electronic Locks RFID start blinking rapidly
indicationg that the indexes wre erased.
