1. At a minimum, the system is to provide the following as recommended by the Federally-adopted

PROWAG (Public Right of Way Accessibility Guidelines) .

a. Location Tone. All buttons should make a sound so they can be located for activation. This sound is to occur once every 3 seconds.

b. Voice On Location. The system is to provide, upon the press of the button, a location message stating the name of the street being crossed, the name of the side street; example

"Wait to Cross Fifth at Penn ".

c. Walk Message. The system is to provide a verbal message during the walk signal;

example "Penn. Walk sign is on to cross Penn ". For "rest in green" conditions the

Accessible Push button is to play for the duration of the WALK signal, minimum 7 seconds.

Play the walk message one, two or three times. The Walk message is to play on all push button stations for that crossing. For exclusive pedestrian phases the system is to say

“WALK SIGN IS ON FOR ALL CROSSINGS”.

d. Directional Arrow. Incorporate a raised/vibrating directional arrow as part of the push button which vibrates for the duration of the Walk message. The arrow is to be oriented parallel to the crosswalk.

e. Push button feedback. Each time the push button is pressed the user is to receive an acknowledgement in the form of a single audible "tick" as well as single momentary vibrating pulse. In addition, an LED is to turn on and latch until the walk signal is displayed. The LED is to latch for all push button stations on that crossing.

f. Fail Safe Feature. In the event the push button station loses power, the system is to automatically place a constant call to the traffic controller.

g. The button is to be a non-mechanical, vandal-resistant type rated using a piezo switch and be designed so that it cannot be made to "stick on".

h. System is to be able to self-test the push button stations and report any faults to the traffic controller.

i. Each audio feature is to be "user" selected and turned on or off accordingly at the intersection.

j. All audible messages and locator tone will be at integral part of the push button assembly.

k. Changes to the operating characteristics to be completed using a web-browser capable device (e.g. laptop, tablet) via either wireless access or an Ethernet port.

l. Mounting height is to be between 40and 44 inches, measured to the top of the push button

(part that is physically pressed).

m. No audible overhead speakers permitted

2. Polara operational settings are to match the following in addition to all previous settings:

a. Extended Push Time = 0s. The message is to play whenever the button is pressed, regardless of duration of press.

b. Locator Tone: Min = 20% / Max = 100%. Volume over ambient = 5 dB

c. All Messages: Min = 45% / Max = 100%. Volume over ambient = 10 dB

d. Quiet Time setting is to be enabled from 9pm to 6am with volume reduction set at

40%.

e. Internal time is to match correct global time with DST enabled.

3. Guardian operational settings are to match the following in addition to all previous settings:

a. Acknowledgement and Extended Press audio files are to be the same. The message is to play whenever the button is pressed, regardless of duration of press.

b. Day Locator Tone: Min = 50 / Max = 95. Left bubble = 49 / Right bubble = 94
