Master/Slave Installation
The Master and Slave Control Units should be located in places that allow for
access to the units, are relatively clean, and afford the units protection from damage
or vandalism. The control units should each be provided with 24VDC at 10amps.
The unit should be located within an acceptable distance to the access control
system so that door status signals and inter-system communications and signals are
not significantly diminished by voltage drop. The master control unit will contain the
input/output wiring to the access control system as well as a connection to the
master camera heads. Every master/slave system will utilize an Ethernet hub,
including the master and all slaves. Accessing the T-DAR system with the User
Interface (on a PC) will require a connection to the hub uplink. The User Interface
will communicate with the T-DAR system directly or through a system network.
Connecting a PC to the Ethernet hub uplink directly may require the use of a
crossover cable. Another approach is to place the T-DAR mantrap system on the
local network, allowing connection from any location.
Bidirectional Mantrap
The Bidirectional Mantrap consists of specialized software that prevents tailgating
during entry and egress through the mantrap area. A standard (unidirectional)
mantrap will only prevent tailgating during entry. Bidirectional software is specialty
software and falls under part number F105. This software is not standard and will
need to be requested by the customer.
A bidirectional mantrap utilizes all the same hardware as a standard mantrap:
generally speaking, two door contacts, two valid access readers, and a public and
secure door lock. Converting a mantrap to bidirectional requires only a software
change.
The entry procedure in a bidirectional mantrap is the same as the entry procedure of
a standard (unidirectional) mantrap. The egress procedure in a bidirectional mantrap
is different than that of a unidirectional mantrap. During egress, once inside the
bidirectional mantrap, a Secure Door Public Side access signal is required to
complete the transaction and proceed through the public door. During egress, both
mantraps require a Secure Door Secure Side valid signal, but only the bidirectional
mantrap requires a Secure Door Public Side grant signal.
T-DAR Stereo Heads
The stereo camera heads must be correct for your application: NTSC or PAL, Visible
or Near IR lighting. Choose the correct stereo camera heads for the distance from
the camera head to the floor.
