Frequently asked questions

Yes! If you have a show you know you’d like to script out, but there’s a few shots you’d love to time for yourself you can do it! All that is needed is to script a show using on the modules and pins that you plan on having scripted. Then once you are armed you can start the scripted show, change over to the manual firing page and fire the other fireworks manually. You are also able to start on manual, go to internal or SMPTE and start that show and even go back to manual firing!

With all mods check which RF they are on, if the firing modules do not match the command module (CM) you can change this manually. On the CM Press [Menu] > 2 on the numpad + ENTER. The Graphical User Interface displays which RF channel is best in your area.

To change the RF channel on all of your firing modules follow these steps:

FM [MENU] > Press [NO ⬇️] and navigate to RF Channel > with the [YES ⬆️] and [NO ⬇️] change the RF channel to match the Command Module’s RF channel and press ENTER.

Our 2Wire connection is designed to be used with any wire that you have laying around (scab wire, multiple conductor, stranded, etc), 2Wire and wireless can be used at the same time as a failsafe, but not necessary. On our modules, you will see 2Wire connectors that can be either inputs or outputs on the 2Wire network. Please reference the below graphic and our manual on the proper way to use our 2Wire connectors.

The max distance between mods while using 2Wire is up to 1,000 feet, however we recommend keeping the distance at 610 feet.

How do I use 2Wire illustration using Command and Firing Modules

We recommend 300-500 feet from mod to mod and elevating them off of the ground, this will dramatically help the radio quality. You can increase the distance by keeping an eye on the link quality between mods.

An additional feature on the Firing mods (FM) is Repeater Mode providing maximum wireless signal strength and more robust timing of the firing signals when you need to go even farther wirelessly. While some systems claim 1.5km ranges, that is in best case scenarios; pyro is seldom fired in best case scenarios.

If the link quality (LQ) on the mods falls to about 40%, then you will need to add a repeater mod. But you’ll want to use as few as possible as each one you add increases the bandwidth usage.

We always recommend using the Wireless Wizard (WW) function to automatically determine what radio frequency will work best in your area.

Turn on mods and press the [No ⬇️ ] – you’ll then see which SW version your mods are.

If updating both Command and Firing Modules, please make sure to update your Firing Modules before running the Command Module update.

Software is updated whenever enough small improvements have been accumulated for release, or a major improvement/fix has been added. There is no set schedule for when or how often an update occurs. If you purchased Firelinx through its website or directly from a sales agent, you will be notified via email when a new software update is available. Additionally, if an update is available, it will be listed on the website under the SUPPORT page with notes regarding what improvements have been made.

To update the Firing Modules (FM), place the update file on a USB stick and insert it into the Command Module (CM). Turn on the CM and all FMs. Make sure all FMs have joined successfully. FMs should have a full battery prior to performing an update, or be plugged in to their charger. On the CM [MENU] > Press [7 Update] on the numpad and press ENTER. The CM will search the USB drive for the update. It will then prompt and inform the user of which update, if any, will be applied, with a Yes/No question. Pressing [YES] will begin the update procedure. During the procedure, do NOT turn off the CM or the FMs during the process. When completed, the FMs will turn off automatically, and the CM will return to the Menu. The procedure can take anywhere from 5-10 minutes depending on the number of FMs connected.

The CM update is performed the same way and it should be completed in under a minute. The CM should always be updated AFTER you have updated the FMs and OPNs.

Updating OPN cards is the same procedure as the FMs, though it can take between 10-20 minutes to complete. If, after an OPN update has occurred, the unit still shows 100% completed without continuing, wait approximately 30 seconds before shutting off the unit (after it reaches 100%).

It is recommended to reboot the CM (power off then power on) between each update to ensure the information it has regarding the FMs is accurate at the time the update is initiated.

If you need to do multiple updates, the proper order is OPN, then FM, then CM. Be aware, if there is an OPN update for an FM, and the CM has the same OPN that needs the update, the FMs will be done first. You’ll need to do the update procedure again to update the CM’s OPN card.

When using SMPTE timecode in a Firelinx show, if experiencing issues, the first thing to do is to double check the frame rate of the SMPTE output and make sure that Firelinx is configured for that frame rate.  Firelinx supports 24, 25, 29.97, and 30fps SMPTE rates.

You can easily check and modify Firelinx’s SMPTE frame rate in the SMPTE menu from the settings menu.

From there you can select the frame rate that properly matches your SMPTE output. If you are unsure what your SMPTE frame rate is, run SMPTE while in the menu and watch the time tick in the menu and see if there are any skips in time. If the time skips the frame rate is likely inaccurate and should be adjusted.

With a wireless operating range of up to 650 feet (200 meters) from command mod to firing mod, or 6500 feet (2000 meters) on 2Wire, distance isn’t an issue.

We STRONGLY recommend only connecting one e-match per pin. You can connect up to three in series, but you run the risk of not firing all. If the first e-match fires first there’s no current running through the rest of the e-matches. Every 175 feet you can drop one e-match, the furthest distance is then dropping 2 e-matches worth of wire leaving one match to fire, equalling 350 feet. We highly recommend not pinning e-matches in series.

We’ve tested about 1000 feet between modules. When wiring e-matches, one end goes into the firing pin and then goes to one wire on the next e-match. The second wire on the second e-match then goes to the only remaining firing pin on the mod or to the next e-match.

Ematch Hooked In series - 6 places

Ematched Hooked in Parallel- 2 places

The reason that continuity testing is so safe on Firelinx is because the Continuity circuits and the Firing circuits are more or less completely disconnected.

 Firing Circuit

The firing circuit’s intended use is to blow up something. Naturally, we want it to only do what it does only when we tell it to. For this reason we have 2 switches on both sides of each firing pin. These circuits only allow energy to pass through when they are told to, when you press the Fire button. We also have those switches connected to our supercapacitor banks, these are huge energy storage devices that can actually fire the matches.

Continuity Circuit

This is a completely different set of switches that are connected to a completely different circuit than the supercapacitors. These are limited to only 1/10 of the minimum amount of energy that it takes to fire any matches. When these fail, the units can detect that more than the allowed amount of energy is being passed through, and the switches shut off and the unit turns yellow which shows failure.

Differences from others

The main difference between our system’s continuity test versus others is that other units have their circuit more or less all as one circuit that has less failsafes in it. If there’s something that goes wrong, the entire battery can dump into their circuit even if it’s just doing continuity because their power source is the battery and their circuits aren’t designed with all the failsafes in mind. Additionally, other systems generally have what is known as a single point-failure, meaning that if any one part of the system fails, the units could fire. Firelinx has no single-point failures within the firing system, meaning that if one part fails, the system will still not fire accidentally. Our system is designed explicitly to avoid these pitfalls by not allowing them to ever cross connect, and if there is any cross connection we have monitors in place to shutdown the unit’s ability to output any power at all.

Firelinx offers wireless and 2Wire connection from mod to mod. The mesh wireless system utilizes an encrypted 2.4 GHz wireless signal to communicate in conjunction with our proprietary algorithms. Firelinx can also be expanded to include Ethernet and other communication connections when needed.

The Command Module comes with rechargeable LiPo batteries which run up to 30 hours.

The Firing Module comes with rechargeable LiPo batteries which run up to 65 hours, with the ability of adding a second battery for twice the run time.

Up to 999 firing modules to one command module.

Firelinx is designed to work with all types of fireworks, from Class-B professional grade fireworks to Class-C consumer grade (assuming the user knows how to wire an e-match to Visco). Whether it’s a 12” shell, cremora, or a cake, Firelinx can shoot it.

Green – Safe mode – not armed

Red – Armed mode – ready to fire

Blue – Continuity test – no shots are detected

Magenta – Continuity test – one or more shots are detected

Yellow – Continuity test – no current flowing through firing pins

If yellow  occurs, please contact Firelinx at

Yellow/Red flashing – System is either arming, or disarming.

After firing your show, you should disarm the system by turning and pulling the key from the Firelinx Command Module. Once that step has taken place, and the modules turn green in the field, you are safe to approach the firing modules with caution. While the firing system will not fire any more, there is always the possibility of delayed explosions or duds on any firework. While Firelinx can provide the best safety in a firing system, this is no replacement for having knowledgeable pyrotechnicians and safety procedures in place to clear a field after a show.
