Introduction

The Axon Signal Unit (ASU) is part of a communications platform that interacts with an

emergency vehicle’s light bar. When the light bar activates, all properly equipped Axon Flex

systems within range begin recording.

For automatic recording to occur, an Axon Flex camera must be attached to an Axon Flex

controller equipped with Axon Signal technology. A controller equipped with this technology has

an Axon logo on the lower-left side of the front of the device. See the TASER Axon Flex System

User Manual for more information.

Failure to follow the instructions in this manual may result in the ASU not working

properly or cause damage to the ASU or the vehicle. Save these instructions.

The technician who installs the ASU must be qualified to work with automotive

electronics.

When installing the ASU, ensure that drilling will not damage the emergency vehicle’s

equipment or surface. Remove all burrs and debris after drilling.

Ensure there is a good electrical ground to the vehicle chassis.

Do not install the ASU anywhere that will interfere with airbag deployment.

Do not install the ASU where it will be exposed to the elements or extreme heat. Do not

install the ASU in the vehicle’s engine compartment.

Characteristics

Secure Bluetooth broadcast (30 seconds).

Activates all enabled cameras in range (30+ feet/9.1+ meters).

Axon Signal Unit Installation Manual The ASU only causes an Axon Flex system to transition from BUFFERING to EVENT mode. You end the recording with a 3-second press of the EVENT button on the Axon Flex controller. Double-pressing the EVENT button on the Axon Flex controller after the EVENT mode is activated by the Axon Signal Unit will not interfere with recording. Installation Instructions  Axon Signal Units are usually installed near the siren box or light bar controller (trunk or console).

Axon Signal Unit Installation Manual 1. Turn on the trigger (that is, turn on the light bar). 2. Use a voltmeter to test the wires that might be connected to the trigger. When you make contact with the correct wire, the voltmeter will indicate its activity. 3. Turn the trigger off and verify that the voltage drops to zero; then you know you have located your trigger wire.

Start the vehicle’s engine. 2. Look at the ASU.  A green POWER light indicates the ASU is powered up.  A green STATUS light indicates a successful startup. o If both lights are on, your ASU is ready and working properly. o If either light is not on, try turning the engine off and restarting it.

Troubleshooting If you finish the installation and the power and status lights do not turn on, the vehicle’s breaker switch might not be turned on. Flip the breaker switch and repeat the instructions in Step 5: Verify the Axon Signal Unit Is Working. If this does not work, there may be an issue with the wiring.
