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
Networking TX3 Panels on page 44 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
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.
