Be generic at this point because we haven't assigned an inspector to the project.

Whoever you want to be the "point of contact" during construction. I can list a generic name if you would rather, but I
recommend a person.

Hello Kim,
To make sure I am understanding you correctly... For the overall
construction/installation of the signal, we do have inspectors that will
be assigned to oversee the correct placement of the mast
arms/foundation/overall signal components, along with inspecting the
entire Deforest Rd project.
Now when it comes to activating the signals, that portion is turned
over to Per.

Diwanna,
Quick question. I typically will list a contact at the city who will
coordinate signal construction. This is typically either an engineer or
a senior signal technician. Who would you like me to list and at what
contact? (May Per Birdsall, since he answered the questions? )
Thanks for your input.

Kim,
I'm afraid you are over my head on some of the specific questions, so I
am going to involve Per in this.
Per,
Please assist these folks with the design of the new traffic signal for
the intersection of Deforest Road and MacArthur Blvd.
Thanks,
Keith

Keith,
I need to know if Coppell has a specific preference for the following
signal
equipment. I have listed several options, but have no preference.

Opticom: Global Traffic Technologies
(9/2/2009) DiWanna Baskins - RE: Coppell Signal Equipment
o Type 711 uni-directional opticom detectors (4) This model of
opticom detector works fine.
o Type 754 - 4 channel phase selector We prefer the 2 channel phase
selector if possible. I believe Model 752 would probably be the call
out.
o Model 380 card rack Good
o Model 138 opticom detector cable Good
VIVDS equipment: Iteris, Autoscope Autoscope Terra Solo
Controller: Naztec (what model?) Naztec 980 NTCIP w/ ethernet
port
Spread Spectrum Radio: Encom 5200 We are not utilizing the
Spread spectrum at all the intersections. At this time I would request
a conduit from Deforest to Samuel in order to have at least coordination
through twisted pair but I believe the future of that intersection is
ethernet over broadband wireless via Samuel & MacArthur. This will take
additional discussion but I still believe in conduit for either fiber or
some type of copper.
Push Button: Polara "Bulldog" (Momentary LEFD Model - BDLM2),
Audible signals are also available, but cost about $1000 each Polara
will be fine, we may need to consider countdown pedestrian displays
(indications) depending on location.
Cabinet: Type 2 (Does Coppell have a standard set-up?) It is
actually a type 1 with some T2 capability. It needs an access panel for
generator plug-in and with automatic power disconnect switch for when
the generator is plugged in. Cabinet size 44"x 68"x 27". Two GFCI AC
outlets, metal air filter, two fans, 24" tall base (TXDOT). The last
model we received from Naztec was 70006 LWSVL.
o Power Cabinet - TxDoT txd 120/240 070(NS) AL(E) PS(U). You may want
to investigate getting power from the lift station and avoiding the
cabinet all together.
In addition, does the City want to include the following
equipment:
o UPS system? Yes, Clary SP Series (SP1250PD-N (plus)) with 6 Outpost
batteries. External battery cabinet 15 '/z" x 36 '/z" x 16", two shelves,
mounted to the signal cabinet.
o Illuminated signs? Yes with logo, our last specification is
attached.
o Confirmation Lights with an independent load panel in the cabinet.

o Upload / dowload device (laptop) -this item is necessary for the
programming and maintenance of the controller, VIVIDS and the battery

Thanks so much for helping me gather the information. Call me if you
have
any questions or want to discuss this further. Also, tell Edith that
