DT Connect works with the Testifire XTR2 by pairing the two devices via Bluetooth, allowing you to control test sequences, adjust settings, and log test results directly from a smartphone or tablet. The DT Connect app communicates wirelessly with the XTR2 head unit, giving you a digital record of every detector test without needing paper logs. Below, we cover everything you need to know about setup, compatibility, recorded data, and common connection issues.

What does DT Connect actually do on the Testifire XTR2?

DT Connect is the companion app for the Testifire XTR2 that turns your smartphone or tablet into a remote control and data logger for the device. Instead of manually operating the XTR2 head unit by hand, you use the app to start and stop test sequences, select test modes, and capture the results of each detector test automatically. This removes the need for handwritten records and gives you a clean digital audit trail.

In practical terms, the app lets you name test locations, assign zone and panel references, and export reports once testing is complete. For anyone responsible for maintaining fire and gas detection systems across multiple spaces or decks, this is a significant time saver. Rather than flipping through paper sheets at the end of a job, you have a structured report ready to share with a superintendent or classification surveyor.

The app also gives you real-time feedback during testing. You can see whether a detector has responded correctly to the test stimulus before moving on to the next unit, which helps you catch faults on the spot rather than discovering them during a review.

What devices are compatible with DT Connect?

DT Connect is designed to work with Testifire products that include built-in Bluetooth connectivity. The Testifire XTR2 is one of the primary devices the app supports. Compatibility depends on the device having the correct hardware and firmware version to communicate with the app over Bluetooth.

Before assuming your existing Testifire equipment will pair with DT Connect, it is worth checking the specific model and firmware version. Older Testifire units without Bluetooth hardware will not be compatible, regardless of firmware updates. The DT Connect app itself is available for both iOS and Android, so compatibility on the mobile side is broad, but the physical Testifire device must support Bluetooth communication for the pairing to work.

If you are unsure whether your current Testifire equipment is compatible, checking the product documentation or reaching out to a knowledgeable supplier is the most reliable route. We help customers confirm compatibility before purchasing or commissioning new equipment, which avoids costly mismatches on board.

How do you set up DT Connect with the Testifire XTR2?

Setting up DT Connect with the Testifire XTR2 is straightforward. You install the app on your mobile device, power on the XTR2, and pair them via Bluetooth. The process takes only a few minutes once both devices are ready.

Here is the general setup sequence:

1. Download the DT Connect app from the App Store or Google Play and install it on your smartphone or tablet.
2. Power on the Testifire XTR2 and ensure Bluetooth is active on the device (refer to the XTR2 user manual for the exact activation step).
3. Open DT Connect and navigate to the device pairing screen.
4. Select your XTR2 from the list of available Bluetooth devices.
5. Once paired, create a new test project within the app, entering details such as vessel name, zone references, and test date.
6. Begin testing detectors using the XTR2 as normal. The app will record each result in real time.

Keep your mobile device close to the XTR2 during testing to maintain a stable Bluetooth connection. Walls, bulkheads, and metal structures on board can reduce signal range, so staying within a few metres of the device is good practice.

What test data can DT Connect record from the XTR2?

DT Connect records a structured set of data for each detector test performed with the Testifire XTR2. This includes the test result (pass or fail), the detector location or reference, the date and time of the test, and the type of test applied. The app compiles this into a report you can export and share.

For maritime applications, this kind of documentation is particularly useful. Classification society surveys and flag state inspections often require evidence that fire detection systems have been tested and maintained correctly. Having a digital report with timestamped results gives you a reliable record that is far easier to present than handwritten logs.

You can typically add custom location labels and notes within the app, which makes it easier to map test results back to specific decks, compartments, or detector zones on your vessel. This level of detail helps when following up on failed detectors or planning maintenance schedules.

Why won’t DT Connect connect to the Testifire XTR2?

The most common reasons DT Connect fails to connect to the Testifire XTR2 are Bluetooth not being enabled on the XTR2, the devices being too far apart, an outdated version of the app, or a firmware version on the XTR2 that is not compatible with the current app release. Working through these in order usually resolves the issue.

Here are the main troubleshooting steps to try:

• Check Bluetooth is active on the XTR2: the device must have Bluetooth enabled, not just powered on.
• Reduce the distance between devices: move your phone or tablet within one to two metres of the XTR2.
• Update the DT Connect app: older versions may not communicate correctly with newer XTR2 firmware.
• Check the XTR2 firmware version: if the firmware is outdated, a firmware update may be needed before the app can pair successfully.
• Restart both devices: power cycling the XTR2 and closing and reopening the app clears most temporary connection errors.
• Unpair and re-pair: if a previous pairing is stored incorrectly, removing the device from your phone’s Bluetooth settings and pairing again often resolves stubborn issues.

If none of these steps resolve the issue, the problem may relate to a hardware fault in the XTR2’s Bluetooth module. In that case, the device will need professional inspection or repair before it can communicate with DT Connect reliably.
