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.

Connection plates
Cabling
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.

position, prefabricated wires and other mounting accessories and options.
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.

Link 4 connection plates
Wiring schematic example using “Link 4” connection plates. Link 4 connection plates are used where
there are single or double lockers in a column. Schematic bellow shows one sided bank of lockers
with 4 lockers per locker block.
Using Link 4 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.

there are multiple lockers in a column. Schematic bellow shows one sided bank of lockers with 16
lockers per locker block.
Using Link 8 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

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.
