1 Introduction
This manual provides information about the installation and operation of the
Telephone Access System, and must be read in its entirety before beginning any
installation work.
Installation must be performed by a qualified technician and must adhere to the
standards and special notices set by the local regulatory bodies.
For warranty and special notices information see the Warranty chapter on page
104 and Special Notices on page 109.
Note: 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 Mircom
website at www.mircom.com.
Warning: The lobby control unit must be grounded by a
qualified electrician. An improperly grounded
unit can result in equipment malfunction and
electrical shock.
If you mount the lobby control unit outdoors,
follow these precautions:
Do not install the lobby unit in direct sunlight.
Use the rain hood and do not expose the lobby
unit to the elements. Make sure the lobby unit
is covered by a minimum 2 m (6 feet) overhang
in all directions.
Seal the openings in the lobby unit with
outdoor-rated weatherproof silicone.
Do not power wash the lobby unit.

8TX3 Telephone Access System Installation and Operation Manual
Introduction
1.1 TX3 Systems
The Mircom's TX3 series of telephone access systems provide high quality two-
way communication between residents and their visitors in a multi-unit dwelling
establishment.
The basic TX3 system consists of the TX3 Lobby Control Unit and depending on
the application, may be integrated with a combination of Mircom Elevator
Restriction Units, Card Access Units and Touch Screens. All access systems
may be networked together using either a peer-to-peer RS-485 connection, an
Ethernet TCP/IP connections, or an Ethernet TCP/IP network with RS-485
subnetworks.
The TX3 system is capable of providing ADC or NSL type telephone access
control from a single panel or from a networked system.
A maximum of 63 units are supported with any combination of Touch Screens,
Lobby Control Units, Elevator Restriction Units and Card Access Units. Valid
network addresses range from 1 to 63. One of the networked units with a real time
clock, such as Touch Screen, Lobby Control or Card Access must have their
network address set to 1. In addition, units can be connected to either an Ethernet
TCP/IP network or a combination Ethernet TCP/IP network with RS-485
subnetworks, both of which allow more than 64 units to be networked. See
section 3.6 on page 34 for more information.
The access system can be configured as an autodialer controller (ADC) or as a no
subscriber line (NSL) system. Both system setups can be configured for multiple
entrances with independent doors and control devices such as electric door locks,
cameras, and garage doors.
1.1.1 ADC and NSL Capability
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.
An ADC connection requires a dedicated subscriber telephone line service
connected to an outside telephone line. This connection lets the visitor call the
tenant and access their voice mail.
An NSL type connection uses the existing building telephone lines for
communication and does not require a separate telephone line. This system may
consist of one or more Lobby Control Units connected to TX3-NSL-8M NSL

Introduction
TX3 Telephone Access System Installation and Operation Manual 9
Units, typically located in the electrical/telephone room of a building. The NSL
units intercept all telephone lines into the building’s suites and communicate
directly to the resident phone using the Lobby Control Unit.
Note: Non-configurable PBX systems are not supported. For more
information, contact technical support at Mircom.
1.1.2 Elevator Restriction Units
The TX3-ER-8-A and TX3-ER-8-B Elevator Restriction Units limit building
accessibility by granting visitor access only to the destination floor.
1.1.3 Other Controllers
Other Mircom controllers, such as the Elevator Restrictor Unit and the Card
Access controller, may be networked with the Lobby Control Unit. The network
options include a peer-to-peer RS-485 network, an Ethernet TCP/IP network, or
a combination Ethernet TCP/IP network with RS-485 subnetworks. See section
3.6 on page 34 for more information.
Notes: In order for a panel to connect to an Ethernet TCP/IP network:
• it must be IP capable. Panels described in this manual are
IP capable.
• it must have a TX3-IP IP Module installed if it is not a
Touch Screen.

2 Enclosure Installation
This chapter provides information on how to install the various enclosures and
panels.
This chapter explains
• Grounding the Telephone Access System
• Installing the Enclosures and Lobby Control Unit
• Installing the Heater
2.1 Grounding the Telephone Access System
Grounding reduces the risk of electrical shock by providing an alternate escape
route for the electrical current. Telephone Access System is equipped with a
16 gauge electrical wire attached to the panel chassis ground post.
To ground the Telephone Access System attach one end of the supplied cable to
a suitable grounding wire and connect it to the site ground.
2.2 Installing the Enclosures and Lobby Control Unit
Lobby Control Units use one of the following three types of Lobby Control Unit
enclosures:
Universal Series. The Universal Series are surface or semi-flush mounted with
the lobby Lobby Control Units. Optional flush trim rings are available for semi-
flush and flush installations. The semi-flush trim is the TX3-UFT. A rain hood is
included allowing for outdoor use.
Universal Slim-Line Series. The Universal Slim-Line series enclosure houses
the TX3-200-4U model and can be surface or semi-flush mounted. The semi-
flush trim is the TX3-USFT.
Continental Series. The Continental Series enclosure for Lobby Control Units
are flush mounted.
