Critical Elements for a Successful T-DAR Installation
The T-DAR
®
system does a superb job of detecting violations of access control
security systems. In order to accomplish this task, the T-DAR requires several
critical elements and/or signals from the doors and the access control system as
detailed in this manual. Three of the most critical elements are:
1.
Door contact/door position switch signals must be immediate. These
signals must be sent to the T-DAR unit at the same time that the door is
opened. Unless it can be verified that the access control system can give
immediate door open signals, the T-DAR unit must have an independent
circuit for this function that allows isolation from the access control system. It
is recommended that mechanical switches of the roller and plunger types be
avoided in favor of magnetic switch door contacts.
2. Adequate and consistent lighting are required for accurate operation of
the T-DAR system. The T-DAR system uses stereo video analysis to
determine three-dimensional characteristics of targets and requires sufficient
lighting to perform this task. Equal and consistent lighting from the ceiling
down allows the system to identify and track targets in all areas of the
detection pattern. Lighting from the sides or the floor is not helpful; in fact it
may detract from system performance. If adequate down lighting is not
currently in place, additional lighting must be added. Invisible (near IR)
lighting is available from Newton.
3. Line-Lock input is critical if low frequency fluorescents are utilized for
lighting.
An ac wall-mounted transformer is included in the T-DAR control unit. If the
lighting in the area that is protected by the T-DAR is provided by low
frequency (older style-line frequency) fluorescents, this transformer or other
low voltage AC source must be used to ensure proper operation of the T-DAR
system. Any source of 6 to 30 VAC will provide the correct line locking of the
T-Dar system to the building lighting.
4. An external power supply is required to provide power to the T-DAR
system .
A power supply that provides 24VDC at 10amps is required for power to the
T-DAR system. A power supply is not included with the T-DAR system.
