SW1
SW1 sets the Telephone Access controller RS-485 network address and
determines how the IP module get its IP address (if installed).
• Use DIP switches 1 to 6 to set the RS-485 network address.
Inputs 1 to 5
Input 1 Postal Lock. Input 1 connects to the Postal Lock. Activation of this
input unlocks the main door and starts the main door timer. Daily usage is
limited according to a pre-defined number.
Input 2 Fire Panel. Input 2 connects to the fire alarm panel and receives fire
notification. Activation of this input unlocks the main and auxiliary doors.
Input 3 Main Door Sense. Input 3 connects to the door sense switch.
Activation of the Main Door Sense locks the main door and resets the main
door open timer.
Inputs 4 and 5 General Purpose. Inputs 4 and 5 are general purpose inputs
that, when configured, activate a general purpose output to perform any
required function.

AC or DC Input Door Strike
The power for the door strike is customer supplied and provides AC or DC
power for one of the door strike outputs. The controller converts an AC
supply to a DC output. The reverse is not true. An AC door strike will not
work with a DC power supply. The maximum supply for the AC or DC Input
Door Strike is not to exceed:
• 28 VAC \ 1 A max
• 30 VDC \ 1 A max
AC Output 1 Door Strike
The AC Output Door Strike receives power from the AC Input Door Strike
supply. The AC power output remains the same as the power supplied to the
AC Input Door Strike.
DC Output 1 Door Strike
The DC Output Door Strike receives power from the AC or DC Input Door
Strike supply. When using a DC Input Door Strike supply, the DC power
output remains the same as the input.
Outputs 2 to 4

(top position for a door strike) or normally closed pin (bottom position for a
maglock).

P5. MD-921 IP Module connector. Only for model numbers ending with
“-A” (for example, TX3-2000-8CH-A).
P6. Key pad and front door LCD display.
P7. Guard Phone Board connector.
RS-485
The RS-485 connection consists of an input and output terminal. Connect the
RS-485 output terminal to the RS-485 input terminal of the next controller.
Connect the last controller on the network to the RS-485 input terminal.
Refer to LT-969 for end of line resistors to be used on the first and last nodes
of network. The RS-485 terminal consists of + (positive), - (negative), and S
(Shield) connections.
Ground Terminal
The Telephone Access system is equipped with a 16 gauge electrical wire
attached to the panel chassis Ground Terminal. Do not disconnect this wire.
Attach the end of the supplied wire to a suitable grounding wire 16 gauge or
thicker. Attach the other end to the cold water ground.
Telephone Lines 1 to 5
TX3 supports full ADC and NSL telephone connectivity from a single
Telephone Access System panel or from a networked system. A single panel
supports up to five ADC and/or NSL telephone lines. Each T/R line is polarity
insensitive and can be reversed.
Note: Non-configurable PBX systems are not supported. For more
information, contact technical support at Mircom.

• Keep DIP switch 7 at the factory set value.
• Set DIP switch 8 OFF to get IP address from DHCP server.
• Set DIP switch 8 ON to get IP address from TX3 Configurator software.

Telephone Access System Quick Reference
Single Entrance System Wiring
Basic Wiring
1
. Turn the controller power switch to OFF.
2
. Connect the telephone line to the Line 1 terminal on the controller board.
3
. Connect the AC or DC door strike.
4
. Connect door strike supply.
5
. Connect the controller supply using 18 gauge wire.
6
. Set JW8 as either normally open or normally closed to control the door strike operation.
7
. Set SW1 with a unique RS-485 network address.
8
. Turn the controller power switch to ON.
Installation Prerequisites
Verify that the building telephone infrastructure is operational. When wiring an NSL installation it may be necessary to
check each resident’s line.
Ensure there is a provision for a ground circuit. The Telephone Access System assembly must be grounded by a qualified
electrician. An improperly grounded unit can result in equipment malfunction and void the warranty.
Use the latest Telephone Access System controller firmware. Mircom periodically updates panel firmware and
Configurator Software to add features and correct any minor inconsistencies. For information about the latest firmware
or software visit the ‘Manuals and Downloads’ section of the Mircom website at www.mircom.com.
Before Starting the Configuration
Configure the system using the front keypad or the Configurator software using a USB or modem connection. Verify the
following:
Ensure that the controller and all connected devices and components are fully operational.
Ensure the controller DIP Switches (SW1) are set with a unique RS-485 network address.
Ensure the Configurator software is set with the correct controller RS-485 network address.
Ensure that your PC is set with the correct date and time.
Wiring requirements
Install all transformers outside the Lobby Control Unit enclosure.
Unless specified otherwise, all wiring is a maximum length of 1000 ft. The RS-485 wiring maximum length is 4000 ft.
All units use the PS-4P transformer for the power supply using 18 gauge wire. The door strike power supply depends
on the door strike power requirements.
The following figure shows the various controller connections
To Start the Configuration
1
. Connect the PC to the controller using the USB port or modem connection.
2
. Launch the Configurator and select the correct controller you are connecting to (on the basis of name, panel label, panel
model, and network address).
3
. Click Connect. Once connected the connection icon appears in the Configurator tool bar.
4
. Ensure that the panel is configured with the correct date and time.
5
. Configure the Telephone Access system using the instructions in the LT-995 Configuration and Administration Manual.
