2 Introduction
2.1 Purpose of this document
This guide covers the installation of the Guardian Pedestrian System. It does not cover the
configuration of the Guardian. For details on configuring the Guardian, please see the User’s
Manual.
2.2 Additional Information
•For operational information, see the Guardian User’s Manual
•Reference the Intersection Worksheet for location specific information.
•See the Guardian Installation Quick Guide for a brief graphical installation guide.
•See the Guardian Base Station Mounting Template for an easy to use hole pattern for
mounting Guardian base stations.
2.3 Contact Information
The first line of contact should be the distributor that the system was purchased from. If you are
unable to contact the distributor, contact Campbell Company directly.

3.2 Installation
It is recommended to use an anti-seize compound on all screws going into the pedestrian
station. Failure to do so may result in damage to the station if removal is necessary.
3.2.1 Tactile Arrow Orientation
Mount the unit so the tactile arrow is pointing directly to the crossing destination. THE
PEDESTRIAN RELIES ON THIE INFORMATION TO CROSS SAFELY. Some installations do
not call out arrow directions and requireinstallation in the field. The tactile arrow is field selectable
(left or right) requiring one security screw and a security driver.
An Angle Mounting Kit for the Guardian Base Station is available if necessary to ensure a precise
fit, especially on decorative or small diameter poles where the station needs to be angled to
provide accurate directionality of the arrow.

3.2.2 Guardian Installation
Drill and Tap Pole
1. Refer to the Guardian Base Station Mounting Template for hole specifications.
2. Mark the point where the PPB will be centered 36” to 42” from the ground.
3. Drill and tap for a 1/4-20 screw 2” above PPB center.
4. Drill and tap for a 1/4-20 screw 8 1/2” above PPB center.
5. Drill a 1” through hole. This hole can be anywhere from 2 1/4” to 5 1/2” below the lower
of the 2 mounting holes (from step 3 above).
Mount the Pedestrian Station
1. Route the four conductor cable from the 1” hole through the pole into the pedestrian
signal head for connection to the SPI.
2. Route the four conductor cable and the field terminal wires through the wire chase at the
bottom of the station.
3. Attach the pedestrian station to the pole using two ¼ - 20 FHP screws.
4. Connect the four wires to the terminal block connections as shown in Figure 1.
5. If there are pedestrian field terminal wires present at the station connect them to the
terminal block in the positions shown in Figure 1.
6. Secure protective terminal door with screws.
7. Attach the adapter plate and/or sign using provided hardware. The adapter plate and
mounting hardware differ depending on size.

3.2.3 400A Station Installation
1. Route the four conductor cable from the pedestrian signal head though the hole in the
station housing.
2. Connect the four conductor cable to the terminal block on the back of the station to the
positions shown in Figure 2.
3. If there are pedestrian field wires present at the station, connect them to the positions
shown in Figure 2.
4. Insert the pushbutton into the 400 style housing and secure using two 1/4-20 screws.

3.2.4 Signal Power Interface Installation
Do not set the SPI on the bottom of the Pedestrian Signal Head. Failure to attach the SPI
vertically on the back surface wall can expose the power supply to water damage and will void
the warranty of the SPI.
Warning! All SPI leads become hot when at least one of the wires is connected. Disconnect the
power to the Pedestrian Signal Head prior to SPI installation
1. Disconnect the power going to the Pedestrian Signal Head prior to installing the SPI.
2. Open the Pedestrian Signal Head Display and locate a ¼-20 tapped hole on the back
wall close to the 120VAC three position barrier strip as shown in Figure 2.

3. Mount the SPI horizontally using a 1/4-20 1” FHP.
It is important that the wires coming out of each
side of the SPI sag below the SPI to prevent
water from running down the wires, into the SPI.
Figure 2 shows the drip loop in the120 VAC lines
and its location to the barrier terminal inside the
Pedestrian Signal Head.
4. Attach the four wires from the Base Station to the
to the four position terminal block on the SPI
following the connections shown in Figure 3.
5. Connect the three 16 AWG wires from the SPI to
the three position terminal block for the pedestrian
signal display.
6. Restore power to the signal head and verify that the station operates.

4 Post Installation
4.1 Operational Check
1. Make sure the station is securely attached to the pole with the arrow pointing to the
crosswalk.
2. Verify that the SPI is mounted horizontally in the signal head with the wiring sagging
below.
3. When first powered up, an audible locator tone will be present at the station. The locator
tone should be audible 6-12 feet from the station.
4. Depress the push button and verify that the LED turns on with an acknowledgement
message. If pedestrian field wires are connected to the station, verify that pedestrian call
is transmitted to the traffic controller.
5. Following a momentary press, verify the Walk message present and the vibro-tactile
surface vibrates when the walk sign is on.
6. Repeat again with an extended press. This time the location message should sound and
walk message should sound when the walk sign is on.
7. After the Walk message, verify that an audible locator tone is present during the clearance
(Flashing Don’t Walk).
8. Recheck all units for a full cycle to ensure all options and features operate as desired.
