Elevator Restriction System Installation and Operation Manual
Introduction
1.2
Terms
1.2.1
TX3 Card Access System
The Card Access System consists of a Card Access Controller (for instance TX3-
CX-2-A), the access points, the cards, and the elevator restriction units. See LT-
980 for instructions on installing a card access system
1.2.2
Access Point (card reader)
When a user swipes a card at a card reader, the system grants access to the user
based on the access level of the card. Card readers can be wired or wireless.
Usually there is a card reader installed inside each elevator cab. The card access
system consists of the access controller, credentials, card readers, elevator
restriction cabinets and door control hardware such as strikes and maglocks. The
access controllers are typically installed in a secure room or locked cabinet. See
LT-980 for instructions on installing card readers. See LT-1160 for information
about wireless card readers.
1.2.3
Access Level
You assign an access level to a card to keep track of access privileges. A card can
have only one access level.
1.2.4
Elevator Restriction Unit (ERU)
Mircom’s Elevator Restriction Units are used with the TX3 card access system to
restrict access to elevator floors based on access level.
An Elevator Restriction Unit (ERU) controls an elevator cab. It is usually
installed in the building’s electrical or telephone room. It has 96 relays which are
wired to the input circuits of the elevator manufacturer’s button controller. When
the relay activates, the button is activated or deactivated depending on how the
system is programmed. In this way, the ERU enables or disables the button for a
configurable amount of time. There should be one Elevator Restriction Unit for
each elevator cab.
1.2.5
Floor Group
A floor group is a group of floors. Floor groups let you give a card or resident
access to a specific group of floors, and restrict access to other.
1.2.6
Old Elevator Restriction Firmware
Old elevator restriction firmware
refers to firmware version 2.0.x and 3.0.x. It
supports basic elevator restriction features.
