Guardian & Guardian Wave Installation Guide

Guardian	Guardian Wave

Overview

This guide provides installation information for the Guardian and Guardian Wave Accessible Pedestrian Signal (APS) systems.

The Guardian APS system operates independently from the traffic cabinet by using a Signal Power Interface (SPI) installed inside the pedestrian signal head. The SPI provides power and signal communication to the Guardian push button station using a four-conductor cable.

This design eliminates the need for APS equipment inside the traffic cabinet and allows installation using existing pedestrian signal wiring.

System Components

A typical Guardian APS installation includes the following components:

• Guardian or Guardian Wave APS station

• Signal Power Interface (SPI)

• Four-conductor cable between SPI and APS station

• Pedestrian sign and mounting hardware

Installation Requirements

Before installation, verify the following:

• Pedestrian signal head has space for the Signal Power Interface (SPI)

• Existing wiring between the signal head and push button station is suitable for reuse

• Mounting location complies with MUTCD and ADA accessibility guidelines

• Push button station height and placement meet local accessibility requirements

Signal Power Interface Installation

The Signal Power Interface (SPI) is installed inside the pedestrian signal head.

Installation steps:

1. Disconnect power to the pedestrian signal circuit.
2. Open the pedestrian signal head housing.
3. Install the SPI module according to the wiring diagram.
4. Connect the WALK and DON’T WALK signal wires to the SPI.
5. Connect the four-conductor cable that runs to the Guardian APS station.
6. Secure the SPI inside the signal head.

APS Station Mounting

Install the Guardian or Guardian Wave station at the pedestrian push button location.

Installation steps:

1. Remove any existing pedestrian push button equipment.
2. Position the Guardian APS station on the mounting pole.
3. Route the four-conductor cable into the station housing.
4. Secure the station using the appropriate mounting hardware.
5. Ensure the tactile arrow is aligned with the direction of travel.

Station Wiring

Connect the field wiring between the SPI and the APS station.

Typical wiring includes:

• Power and communication from the SPI to the APS station

• Four-conductor cable between the signal head and station

Verify correct wiring before restoring power to the system.

System Verification

After installation is complete:

1. Restore power to the pedestrian signal circuit.
2. Verify the locator tone is active.
3. Press the push button to place a pedestrian call.
4. Confirm audible walk indication during the WALK phase.
5. Verify vibrotactile arrow operation.
6. Confirm correct operation of extended button press features.

For Guardian Wave stations, also verify hand-wave detection activates a pedestrian call.
