Quick Installation Guide
TW-EF45

Recommended Mounting Information
•Strong ambient light and / or direct light into the front side of the EF-45 should
be avoided. Sunlight, halogen lamps or other strong illumination may reduce
the performance of the EF-45 and may result in increased failure-to-capture
rates or failed authentication events.
Note: Installation in extreme environments without proper protection may cause
permanent damage and void warranty.

Dimension of EF-45
• The TW EF-45 was designed for indoor use only. This unit is not weatherproof
and must not be exposed to water, ice, extreme temperatures or other adverse
weather conditions. If it is required to use this unit in outdoor or extreme
environments
.
•The recommended mounting height for the TW EF-45 is 155cm (61 inches)
from floor to the bottom of
TW EF-45. The mounting height can be adjusted
to accommodate the height of the average user within the population.

General Wiring Requirements
The EF-45 requires at least the following wiring:
•Ethernet cable: Cat5 cable or better is recommended.
•Power input cable
-AWG 22: less than 5 meters (Max. 7.5m)
•Power Input requirement: 12VDC +/- 5%, minimum 42W (12VDC @ 3.5 amps)
Note: Use stable power supply and shorter power input cable if possible with
correct gauge wire. Any over- or under-voltage applied to this unit may cause
permanent damage and void the warranty.
Standard Installation to Wall Surface or Gang Box
Detach the installation plate from the EF-45 by removing the screw (M3 x 6mm) at the
bottom of unit. Separate the wall plate from the rear cover by sliding the plate
downward. Screw will be re-used to attach the EF-45 to the wall plate following
installation of the wall plate and wiring.
•Installation can be accomplished by mounting directly to a wall (Surface Mount)
or to a Gang Box.
•For a Surface Mount installation, place the installation (wall) plate on the desired
wall location and screw into wall as indicated in the Surface Mount diagram
below. Ensure that bottom tab in plate faces outward and cable routing
opening in EF-45 matches opening in wall. Utilization of wall anchors is
mandatory.
M3 x 6mm screw. Can be
replaced with a M3 security
type screw of proper length.

Wall Mount Installation
Gang Box Installation
For a Gang Box installation, place installation (wall) plate over gang box, and attached
with screws as indicated below while ensuring the cables go through the rectangular
hole.Make sure that the tab at bottom of plate faces outward.

Attaching EF-45 to Wall Bracket
Slide the EF-45 into the installation wall bracket (back plate) from the top.
Lock the EF-45 with bracket using M3 x 6mm screw on bottom.Installers are welcome
to utilize security type screws.

Connector Information
LAN Connector
RJ-45 connector for 10/100Base-T Ethernet communication, minimum CAT5 cable.
RS-485 Termination Resistor Switch
Switch for 100 Ohm termination resistor activation when EF-45 is connected to the
end of RS-485 wire connection.
Default: Turned off

This is used for communication with Access Control Unit or remote PC based
system or controller.
RS-232 Connector
This allows for external communications with serial device similar to Smart Card
Reader or Pin-PAD.
RS-485 Connector

GPI Connector
GPI input is used for sensing the Exit button or Door Open Sensor.
It is TTL level based circuit and is pulled-up by an internal resistor.
Wiegand Input Connector
The Wiegand Input DATA0 and DATA1 are pulled-up by internal DC +5V supply.

Wiegand Output Connector
To make Wiegand Out work properly, the DATA0 and DATA1 should be pulled up
by 1K Ohm resistor unless the EF-45 is connected to external device with its own
pull-up for Wiegand.
DC Power Input Connector
Clean and sustainable DC +12V / 3.2 A power is needed for reliable EF-45
operations.
Relay Connector
Internal relay interface with nominal switching capacity of 1A 30VDC or 0.3A
124VAC, resistive load.

Factory Reset Switch
If Factory Reset Switch is pushed for over 3 seconds, then system will re-initialize all
the parameters to default and reboot the system.
External Audio Output Connector
Connector for external audio output.
Serial Debug Port
This serial debug port is used for debugging the system by CMITech Service or
Engineering.It is not available to user.
