Changing the flash pattern on your beacon typically involves specific wiring interactions, often using a dedicated control wire like a yellow wire. To cycle through patterns or reset your beacon, you will interact with this wire by connecting it to the positive power source for varying durations.
Understanding Your Beacon's Flash Pattern Control
Many modern beacons, especially those designed for emergency or utility vehicles, include a built-in controller for their flash patterns. This control is frequently managed through a specific wire, often colored yellow, which interacts with the main power supply. It's crucial to identify this wire correctly and understand its function according to your specific beacon's design. Always consult your beacon's manufacturer's guide or website for the most accurate wiring diagrams and instructions relevant to your model.
Step-by-Step Guide to Changing Flash Patterns
Here's how to change the flash pattern using the yellow control wire method:
Prerequisites for Safe Operation
Before attempting any wiring changes, always prioritize safety:
- Disconnect Power: Ensure your vehicle or power source is turned off and disconnected from the beacon to prevent electrical shock or damage.
- Identify Wires: Confirm you have correctly identified the beacon's positive, negative, and flash pattern control (yellow) wires. Misidentification can lead to incorrect operation or damage.
- Tools: Have appropriate wiring tools ready, such as wire strippers, crimpers, and electrical tape or connectors.
Resetting to the First Pattern and Syncing
If you need to reset all connected lights to their initial flash pattern or ensure they flash in perfect synchronization, follow these steps:
- Locate Yellow Wires: Gather all the yellow control wires from your beacon (or multiple beacons if they are intended to sync).
- Connect to Positive for 5 Seconds: Connect all these yellow wires together, and then touch this combined connection to the positive power supply for approximately 5 seconds.
- Observe Reset: After 5 seconds, remove the yellow wires from the positive connection. All the lights should now revert to their first flash pattern and flash in unison.
Advancing to the Next Flash Pattern
Once your beacon is reset or if you simply wish to cycle to the next available pattern:
- Locate Yellow Wires: Identify the yellow control wire(s).
- Momentarily Touch to Positive: Briefly touch the yellow wire(s) to the positive power supply for a moment, then immediately remove it. Do not hold it for an extended period.
- Observe Pattern Change: Each momentary touch should advance the beacon to the next flash pattern in its sequence. Repeat this step until you find your desired pattern.
Quick Reference for Flash Pattern Control
To simplify the process, here's a summary of the actions and their results:
| Action | Result |
|---|---|
| Connect all Yellow wires to positive for 5s | Resets to the first flash pattern; all connected lights will sync. |
| Momentarily touch Yellow wires to positive | Advances to the next flash pattern in the sequence. |
Important Considerations
- Manufacturer's Instructions: The method described above is common for many beacons. However, always refer to your specific beacon's user manual or the manufacturer's website (e.g., www.yourbeaconbrand.com/support - placeholder, check your actual brand) for precise instructions. Different models or brands might use different wiring colors or control methods.
- Troubleshooting: If the pattern doesn't change, double-check your connections and ensure the power supply is adequate.
- Professional Installation: If you are unsure about wiring or electrical systems, it is always recommended to seek assistance from a qualified auto electrician or technician.
